Unformatted text preview: 2 is contradicted by the paragraph. Choice 4 is true of billfish, not bluefin tuna. 11. ○2 This is an Insert Text question. You can see the four black squares in paragraph 6 that represent the possible answer choices here. The last sentence of paragraph 5 is also reproduced below. Again, supersonic jets have similar features. ■Because they are always swimming, tunas simply have to open their mouths and water is forced in and over their gills. ■ Accordingly, they have lost most of the muscles that other fishes use to suck in water and push it past the gills. In fact, tunas must swim to breathe. ■They must also keep swimming to keep from sinking, since most have largely or completely lost the swim bladder, the gas­filled sac that helps most other fish remain buoyant. The sentence provided, "Consequently, tunas do not need to suck in water," is best inserted at square 2. The sentence provides an explanation for the muscle loss described in the sentence that follows square 2 and is a result of the fact described in the preceding sentence, which says that because the fish are always swimming, they only have to open their mouths to suck in water. Thus if the provided sentence is inserted at square 2, it provides a logical bridge between cause and effect. The sentence makes no logical sense anywhere else. 12.○Reducing Water Resistance: 1, 4, 5 61 Mail@liuwenyong.com 在在在在在在 www.liuwenyong.com 在在在在在在在在在在在在在在在,在在在在在在在在在在 ○Increasing Thrust: 2, 7 This is a Fill in a Table question.
