Sample Test Questions (XI Science) PREFACE These Sample Test Questions have been specially prepared for KIST grade XI students. The Sample Test Questions are based on the latest syllabi and question patterns of the final examinations as guided by NEB. This test material will help students to get fully acquainted with the types of questions they are likely to be asked. It will also serve as highly effective practice material. This booklet is only a useful collection of sample question papers which cannot possibly cover the whole curricula/syllabi for reasons of space or selection. Hence, students are advised to revise the whole curricula/syllabi and to read suggested textbooks, class notes, and reference materials. Despite all our care and effort and our best intentions, there might still be some technical shortcomings for which we render our apologies.

Computer Science 130-139 KIST COLLEGE & SS Sample Test Questions (XI Science) TEST PREPARATION GUIDELINES In order to achieve the best possible results in examinations, students generally have to develop proper study habits, to organize themselves well, to manage their time strictly, and to work on their own. In particular, to prepare well for the coming Final Examination, students should allocate adequate time each day so that course study should be unfailingly done, and all these model tests are invariably completed. While preparing for the final examination exams, students need to identify which topics they require to focus on, and to prioritize their subject strengths and weaknesses. Importantly, a positive attitude harvests scholastic success and at the same time eliminates stress. Be prepared. Be confident. Parents/Guardians ought to monitor their wards to ensure the completion of the given model test questions after college hours at home and during the pre-exam preparatory period. KIST COLLEGE & SS 3 Sample Test Questions (XI Science) PROCEDURE FOR TEST COMPLETION Students are advised to answer these Sample Test Questions in all seriousness treating them as mock exams. A schedule would have to be drawn up by the concerned student to complete each test at a single sitting so that all the given tests are finished before the final examinations. The sample test questions must be completed silently without any disturbance within the stipulated time without consulting books/notes/any other resource materials or other students while actually doing these papers. Once each test is finished, the student herself/himself has to check & mark her/his own answers on the same day itself. The purpose behind self-marking is to develop the sense and skill of proper selfevaluation tempered with honesty and to nurture exam-related skills yoked to pragmatism. After such self-appraisal, class notes, textbooks, and handouts should be consulted to analyze whether the self-evaluation is accurate and to revise parts of the syllabi covered thoroughly. Peer consultation which aids interactive learning is a vital component to clear confusion and to aid better understanding. Consulting the subject teachers, finally, if there is any point needing clarification or instruction is essential.

Read the text and do the tasks. 15 Mt Everest grows by nearly a metre to new height The world's highest mountain Mount Everest is 0.86m higher than had been previously officially calculated, Nepal and China have jointly announced. Until now the countries differed over whether to add the snow cap on top. The new height is 8,848.86m (29,032 ft). China's previous official measurement of 8,844.43m had put the mountain nearly four metres lower than Nepal's. Everest Officials at Nepal's foreign ministry and department of survey said surveyors from both countries had coordinated to agree on the new height. The agreement to jointly announce the new measurement of the Earth's highest point was made during Chinese President Xi Jinping's visit to the Nepalese capital, Kathmandu last year. Chinese authorities had said previously Mount Everest should be measured to its rock height, while Nepalese authorities argued the snow on top of the summit should be included. The Chinese surveyors had calculated their figure after they measured the mountain in 2005. Nepal's government officials told the BBC in 2012 that they were under pressure from China to accept the Chinese height and therefore they had decided to go for a fresh measurement to "set the record straight once and for all". The 8,848m height, Nepal had been using for Mount Everest was determined by the Survey of India in 1954, but for the first time the country has now conducted its own measurement of the summit. Four Nepalese land surveyors spent two years training for the mission, before heading to the summit. "Before this, we had never done the measurement ourselves," Damodar Dhakal, spokesman at Nepal's department of survey, told the BBC. "Now that we have a young, technical team [who could also go to the Everest summit], we could do it on our own," Mr. Dhakal said. Nepal's lead surveyor Khimlal Gautam lost his toe due to frostbite while on the summit to install height-measuring equipment last year. "For summiteers, scaling the highest peak means a great accomplishment. For us, it was just the beginning," Mr. Gautam had told BBC Nepali after his return. "Unlike other surveys of the Everest in the past, we chose 03:00 to minimise errors that could have been caused because of sunlight in the day time." KIST COLLEGE & SS 34 Sample Test Questions (XI Science) Some geologists have suggested a major earthquake in 2015 may have had an impact on Mount Everest's height. The 7.8 magnitude earthquake killed nearly 9,000 people in Nepal, and caused an avalanche which buried parts of the base camp at the mountain. At least 18 climbers were killed. Some geologists said the earthquake may have caused Everest's snow cap to shrink. Scientists had found that some other Himalayan peaks such as Langtang Himal, mostly to the north of Kathmandu and close to the epicentre, had reduced in height by approximately a metre after the earthquake. Others have argued that Mount Everest, like other Himalayan peaks, may have actually grown over time because of the shifting tectonic plates it sits on. But experts say major earthquakes can result in that process being reversed. "The 2015 earthquake is also a major reason why we re-measured the mountain," said Mr. Dhakal. A. Choose the best answer.

Read the text and do the tasks. I have said this much because it is my wish that the principles which have guided me in the composition of these memoirs may be understood. I am aware that they will not please every reader; that is a success to which I cannot pretend. Some merit, however, may be allowed me on account of the labour I have undergone. It has neither been of a slight nor an agreeable kind. I made it a rule to read everything that has been written respecting Napoleon, and I have had to decipher many of his autographed documents, though no longer so familiar with his scrawl as formerly. I say decipher, because a real cipher might often be much more readily understood than the handwriting of Napoleon. My own notes, too, which were often very hastily made, in the hand I wrote in my youth, have sometimes also much embarrassed me. My long and intimate connection with Bonaparte from boyhood, my close relations with him when he was General, Consul and Emperor, enabled me to see and appreciate all that was projected and all that was done during that considerable and momentous period of time. I not only had the opportunity of being present at the conception and the execution of the extraordinary deeds of one of the ablest men nature ever formed, but, notwithstanding an almost unceasing application to business, I found means to employ the few moments of leisure which Bonaparte left at my disposal in making notes, collecting documents and in recording for history the facts respecting which the truth could otherwise with difficulty be ascertained; and more particularly in collecting those ideas, often profound, brilliant, and striking, but always remarkable, to which Bonaparte gave expression in the overflowing frankness of confidential intimacy. The knowledge that I possessed much important information has exposed me to many inquiries, and wherever I have resided since my retirement from public affairs, much of my time has been spent in replying to Questions. The wish to be acquainted with the minutest details of the life of a famous man is very natural; and the observation on my replies by those who heard them always was, “You should publish your memoirs!” KIST COLLEGE & SS 39 Sample Test Questions (XI Science) A.

KIST COLLEGE & SS 42 Sample Test Questions (XI Science) KIST College & SS Kamalpokhari, Kathmandu Model Questions F.M.: 75 Time: 3 hrs Class – XI Subject: English [ENG. 003] [Set B] Attempt all the questions 1. Read the given text and do the tasks that follow. Reading Comprehension (RC, as it is normally called) is the most peculiar section in almost all scholastic, entrance and employment tests. The skills in RC make a lot of difference to one’s chances of good grades/selection. Most students find it difficult to tackle topics that are diverse from the field they are in or they are comfortable with. So one needs to develop a taste for even the most obscure and boring topic on this planet. For success in RC one should be able to understand. And even with an average speed one can succeed if one implements the strategies. Broadly speaking, RC passages can be classified in a few categories. Fact based RC is the simplest form of RC. These types of passages have lot of information in the form of names, numbers etc. In this type of passages one should read very fast. Don’t try to memorize any facts, numbers or names etc. In fact there is no need to even remember them. Just make yourself familiar with the structure of the passage. Just see in which paragraph author is talking about what. Mark it. Then when you go to the questions, identify in which paragraph information regarding that question is mentioned. Go to that paragraph, read the numbers, names etc. and mark the answer. Inference based RC is the toughest form of RC. Here the passage is fairly tough to understand. This includes passages on topics like Religion, Spirituality, Philosophy, etc. Most of the students will be comfortable attempting these passages at least in RC. The reading speed is fairly slow in this type of passages. The way to master this type of passages is to read them again and again while practising. Topic based RC includes passages on any particular topic like economics, astrology, medical science, etc. Generally, what makes -these passages tough is usage of technical terms. If a topic is new to us, then presence of technical term scares us even if they are defined in the passage. For success in this type of passages we need to have a fan-understanding of the definition of the term if it is defined in the passage. Read that definition twice if you need to. But don’t worry about technical terms if they are not defined in the passage. Assume them to be KIST COLLEGE & SS 43 Sample Test Questions (XI Science) non-existent and proceed. Key principle in these passages is that don’t go to the next line unless the previous line is clear. Reading passage first and then questions is the most popular strategy for RC. While answering the question you may come back to the passage to find answer as you have just read the passage initially and not crammed it. But you should not come back for each and every question. If you come back for majority of questions, then you haven’t read the passage properly. The key to success for this strategy is that you should understand the passage very well. We will suggest students to follow this technique from the beginning and work upon this. Reading questions first and then passage is the strategy followed by a few students. They just look at the questions and not options. The objective is that after seeing the questions when you read the passage then you read only that part carefully where the answer is given. The flaw with this is that you will not be able to remember all the questions. Besides this, this strategy fails when there are questions that require understanding of the passage. A. Answer the following questions by choosing the most appropriate option: [5] a. Most students find Reading Comprehension difficult because……… i) the language is tough ii) the vocabulary is difficult iii) the style is too involved iv) the topics are unrelated to their interest b.

Read the following passage and do the activities that follow. On April 15, a Norwegian mountaineer who complained of cough and fever at Everest base camp was airlifted to a hospital in Kathmandu. He was later diagnosed with Covid-19. More than two dozen high-altitude rescues have been conducted since then, “all related to” severe high-altitude illness, according to the Himalayan Rescue Association and helicopter companies. As a precautionary measure, authorities had issued circulars two weeks ago asking expedition groups to stay within their bubble, but the evacuations have rung alarm bells loud and clear. There have been a dozen other suspected cases, but government officials and the Nepal Mountaineering Association have simply dismissed them. But things could change. On Tuesday, four Sherpa’s were evacuated from Dhaulagiri base camp after developing Covid-19-like symptoms. They all tested positive on Wednesday, leaving the expedition agency no choice but to evacuate nine other climbers. The fresh incident has stoked fears of infection at Everest base camp, where expedition groups have installed boundary ropes to separate one tent from another, and people’s movement has been restricted. On Thursday, Nepal reported yet another record single-day new infections with 8,970 cases and 54 deaths. While the government and mountaineering officials continue to dismiss coronavirus cases at base camp, at least two dozen climbers are said to be suffering from “serious coughing”, and it is unclear whether the cough is due to a combination of high-altitude and low relative humidity or Covid-19. Without testing, which is not available at base camp, there is no way to rule out coronavirus on Everest, but doctors stationed at the camp say there have been many altitude cases this season, which have symptoms similar to Covid-19, and climbers should be evacuated should illness last for five days. Earlier in January, the local administration in Nepal’s Everest region lifted all Covid-19 restrictions in an attempt to woo back trekkers to its popular trails. Tourists were no longer required to submit a 72-hour negative PCR test report or meet quarantine provisions. The municipality decision had followed a drop in new KIST COLLEGE & SS 47 Sample Test Questions (XI Science) infections and the lifting of restrictions at large as the government prepared to launch the first phase of the vaccination drive. As a Plan B, local officials told this paper that antigen tests would be arranged if travelers were suspected of developing Covid-19 symptoms. All this followed the government decision in September last year to allow tourists into Nepal for trekking and mountaineering, nearly seven months after imposing a nationwide lockdown. Last month when the Department of Tourism issued a directive introducing a quota system in a desperate measure to prevent overcrowding on the world’s tallest peak amid the second wave of the pandemic, the department had already issued 377 climbing permits. A record 408 mountaineers have been granted permission this year. This is an all-time high number of permits issued in a season, and expedition members have all assembled at Everest base camp at an altitude of 5,500 metres. As the window to begin the ascent starts on Sunday, concerns are now growing that the coronavirus has made it to base camp, where some 2,000 expedition members have gathered. While expedition agencies claim that their clients are all isolated and safe, and health safety measures are being enforced in the respective camps, it is important to note that although the mountaineers were required to submit a negative PCR report before hitting the trails, it wasn’t mandatory for Nepalese and high-altitude climbing guides. This is a huge margin of error, one that risks live and a lost opportunity to ensure a safe bubble for the Everest season. A. Choose the best answer. (5x1=5) st a. The word ‘mountaineer’ in the 1 line means: i. a person who climbs mountains as a sport ii. a person who lives in mountain region iii. Sherpa’s of Nepal b.

Read the following blog about the influence of social media, and answer the given questions. During the middle Ages (from about 500 C.E. to the mid-1400s) there were no great changes in the way of life in Europe. People did what their forefathers did before them, and there were few new inventions or discoveries. Most people believed in what they were told and did not care about anything outside their lives. One reason for this may be because only a few people received an education, and books were scarce. Then, a change began. People became better educated, trade and industry developed, the arts flourished, and explorers discovered new lands. We call this great change the Renaissance, which in French means "rebirth". The Renaissance, which took place in Europe between the thirteenth and sixteenth centuries, was a new stage in the history of the world. Some people think that the Renaissance got started when the Turks took over the Greek city Constantinople (now Istanbul) in 1453. Greek scholars left Constantinople and settled in other parts of Europe. In these new locations, they taught Greek and shared their precious books. The study of classical Greek and Roman writers and thinkers began again, and a new desire for learning spread throughout Europe. People began to inquire into everything, and some began to question their beliefs and ways of thinking. In Germany, Martin Luther started a revolt against the conventions of the Roman Catholic Church. Soon, other Christians agreed that the Church needed to change, and several new Christian religions were established. Other people began to think about new types of government that were based on the democratic values of ancient Greece. Italy, the birthplace of the Renaissance, was organized into city-states that governed themselves. Though wealthy families and the Church held much of the power in these areas, the city-states were moving a step in the direction of government by the people. The most famous political thinker of the Renaissance was Niccolo Machiavelli. In his book on government entitled The Prince, he stated that a good leader could do bad and dishonest things in order to preserve his power and protect his government. Though people in his own time thought that Machiavelli was evil for saying these things, his book is now famous and modern political thinkers respect some of his ideas. KIST COLLEGE & SS 52 Sample Test Questions (XI Science) The "new learning" taught people to think in new ways, and it also encouraged gifted people to paint pictures, make statues and buildings, and write great literature. In fact, some of the best artists of the day did all of these things. As a result, when a person today is skilled in many areas, he or she is often called a "Renaissance man" or a "Renaissance woman". The artistic developments of the Renaissance first happened in the Italian city of Florence, and then they spread to other Italian cities. As a result of trade and banking, cities like Florence, Venice, and Milan became very wealthy, and their rich citizens had both the time and money to enjoy music, art, and poetry. These cities produced great painters and sculptors, like Michelangelo, Leonardo da Vinci, and Raphael. These artists created some of history's finest works of art. For example, Michelangelo spent four years painting thousands of feet of curved ceiling in the Vatican's Sistine Chapel. To do this, he had to learn a whole new style of painting. He also had to paint lying on his back beneath the ceiling as paint dripped down onto his face. Despite these obstacles, he created one of art's greatest masterpieces. A.
