The numbered points along the river were chosen by scientists as various town sites where the water quality would be tested. They rated the samples, according to several factors, on a scale from 1 to 10, where 10 is the best water quality. The scientists noted that there was much less human development (such as homes, factories or roads) around sites 1, 3, and 4. Site 1 2 3 4 5 6 Rating 3 7 2 8 7 1 http://alberta.exambank.com/cgi-bin/examinator2/68/092CJUYJXJF1R447H6H 2016-10-10 ExamBank Practice Exam for Science 6, Unit 4: Evidence and Investigation, 10 Questions Page 3 of 6 We can infer that contaminating agents are being introduced into the river in which of the following areas in town? A) between sites 2 and 4 B) between sites 5 and 6 C) between sites 6 and 3 D) between sites 3 and 1 4. Refer to the information in question 3. Beyond Site 1, there is dense, lush rainforest and little development. So little, in fact, that the scientists were unable to travel there to collect a sample. They have hired you to estimate what the water quality might be in this undisturbed environment. Based on the collected results, what would you expect the water quality to be downstream from Site 1? (Give a whole number estimate.) 5. Refer to the information in question 3. Many of the townspeople believe that the main cause of the poor water quality at Site 6 is contamination from the city upstream (not on the map). Based on the results of the water quality test, is this assumption fair? A) Yes B) No 6. Mrs. Robins decides to take her class on a field trip to the zoo.
