In the right-hand column, you will find alternatives for the underlined part. In most cases, you are to choose the one that best expresses the idea, makes the statement appropriate for standard written English, or is worded most consistently with the style and tone of the passage as a whole. If you think the original version is best, choose “NO CHANGE.” In some cases, you will find in the right-hand column a question about the underlined part. You are to choose the best answer to the question. You will also find questions about a section of the passage, or about the passage as a whole. These questions do not refer to an underlined portion of the passage, but rather are identified by a number or numbers in a box. For each question, choose the alternative you consider best and fill in the corresponding oval on your answer document. Read each passage through once before you begin to answer the questions that accompany it. For many of the questions, you must read several sentences beyond the question to determine the answer. Be sure that you have read far enough ahead each time you choose an alternative.

I ran over to find a girl standing there, brushing dirt from her jeans. The seat of the nearest swing dangled from one chain while the other chain swayed back and forth, unattached. No one else had witnessed what I 8 had; I realized I’d found my story. [5] Later that day, while I hand-delivered copies of my 9 broken swing story to every house on the block.

[ D] Ten-foot-wide culverts and small concrete tunnels allow animals of various sizes to pass under the highway 5 21. If the writer were to add the phrase “ even in groups” at this point (adjusting the punctuation as needed), the paragraph would primarily gain: A . an indication that many animals living near US Highway 93 have grown accustomed to traveling alone, even during migration periods. B. a detail that emphasizes that the culverts and tunnels were specially designed to accommodate animals’ needs. C . a suggesti on that more groups of l arge ani mal s than groups of small animals have been using the crossings to travel together.

Then, when a food containing acid (which generally causes a sour taste) is consumed, this molecular bond intensifies. This reaction, in turn, transmits a signal indicating sweetness to the brain. Thus, acidic foods with sour or bitter flavors register as sweet. Raw lemon slices taste like candy. ACT-F12 9 G O O N TO THE NEXT PAG E. 1 1 50.

To avoid difficulties in shipping the delicate berries, his company sells them in frozen and dried forms and it also sells them 55 56. At this point, the writer is considering adding the following true statement: Mozie has said that his favorite foods to eat with miracle fruit include green mangoes and oysters with lemon juice. Should the writer make this addition here? F. Yes, because it offers an informed opinion on a subject with which many people may be unfamiliar. G . Yes, because it provides examples of acidic foods that pair well with miracle fruit. H .
