Choice2 is the best answer. It is esse ntially a rephrasing of the statement in paragraph 1 that blowholes cannot disguise cetaceans’ affinitie s with other mammals. The other three c hoice s are refuted, either directly or indirectly, by that paragraph.2．○ 1This is an Infere nce que stion asking for information that can be inferred from paragraph 1 . Choice 1 is the best answer because paragraph 1 says that sea otters are unlike early mammals whose appearances are not easy to imagine. By inference, then, the early appearance of sea otters m ust be ea sy (or not difficult) to imagine.3．○ 3This is a Vocabulary question. The word being tested is precious. It is highlighted in the passage. The correct answer is c hoice 3, valuable. Anything that is precious is very im portant and therefore valuable.4. ○ 3This is a Factual Information que stion asking for spec ific infor mation that can be found in the passage. Choice3 is the best answer. Paragraph 3 describes the differences a nd similaritie s between Pa kicetus and m odern cetaceans. Sentence 3 of that paragraph states that their skulls are similar. The other three choices describe difference s, not similarities.5. ○1This is a Reference question. The word be ing tested is It. That word is highlighted in the passage. This is a simple pr onoun referent item. Choice I , Pakicetus is the c orrect answer. The word It here refer s to a creature that probably bred and gave birth on land. Pakicetus is the only one of the c hoice s to which this could apply.6. ○2This is a Vocabulary que stion. The word bei ng tested is exposed. It is highlighted in the pa ssage. The correct answer is choice 2, visible. Exposed means unc overed. A skeleton that is uncovered can be seen. Visible means can be seen.7. ○ 4This is a Factual Information que stion asking for spec ific infor mation that can be found in the passage. Choice4 is the best answer because it is the only detail about the skeleton of Basilosaurus mentioned in paragraph 4, meaning that it is significant. Choice 1 is true, but it is not discussed in the detail that choice 4 is, and does not represent the significance of the discovery. Choice 3 is not mentioned, and c hoice 2 is not :me.8. ○4This is an Inference que stion a sking for a conclusion that can be drawn from the e ntire passage. Choice 4 is the best answer ba sed on the last sentence of paragraph 4, which de scribe s Basilosaurus as a fully marine whale. That implie s that everything it did, including breeding and giving birth, could have been done only in a marine envir onme nt.9. ○2This is an Inference question asking for a conclusion that can be drawn from the passage. Paragraph 5 explains that this discover y provided im portant information to scientist s that they might not have been able to obtain without it. Therefore, you can infer that the discovery wa s a lucky one. The passage offer s no support for the other choices. Therefore, choice 2 is the best answer.10. ○3This is a Sentence Sim plification question. As with all of the se items, a single sentence in the pa ssage is highlighted:The structure of the backbone shows, howe ver, that Ambulocetus swam like modern whale s by m oving the rear portion of its body up and dow n, even though a fluke was missing.Choice 3 is the be st answer because it contains all of the essential information in the highlighted sentence. Choice 1 is not true because A mbulocetus did have a backbone. Choice 2 is not true because the sentence says that the backbone showed how the Ambulocetus swam, not that it was missing a fluke. Choice 4 is untrue because the se ntence states that Ambulocetus and moder n whales swam in the same way.11. ○4This is a Vocabulary question. The word bei ng tested is propulsion. It is highlighted in the pa ssage. Choice 4, moving forward is the be st answer because it means the action of prope lling. The whale in the sentence used its hind legs to push itsel f forward in the water.12. ○2This is an Insert Text question. You can see the four black squares in paragraphs 1 and 2 that represe nt thepossible answer choices here.Extinct but already fully marine cetaceans are known fr om the fossil record. ■ How was t he gap between a walking mammal and a swim ming whale bridged? ■ M。
