Solutions with explanations to Reading Test 1 Section 1 : Cambridge 7

Questions 1-5: Identifying information (You have to match the information with the paragraph)

Answers:

1. B (in Paragraph B, Line 2, 3 and 4 talks about other insects and animals which don’t depend on eyesight, e.g. night flying insects, Deep-sea fish and whales, fish and dolphins )
2. A (in Paragraph A, line 9 and 10 says, “when dinosaurs dominated the daytime economy, our mammalian ancestors probably only managed to survive at all because they found ways of scraping a living at night.” Thus, early mammals avoided dying out.)
3. A (in Paragraph A, line 3, 4 and 5 says, “natural selection has favoured bats that make a go of the night-hunting trade. It means bats are naturally night-hunters.)
4. E (in Paragraph E, line 6, 7, 8,and 9 talks about the discovery of SONAR, ” the underlying mathematical theories of radar and sonar are very similar; and much of our scientific understanding of the details of what bats are doing has come from applying radar theory to them.” )
5. D (in Paragraph D, line 12, 13 and 14 talks about the use of “echolocation” / sonar/ radar in The Second World War. “Both sides in the Second World War relied heavily on these devices, under such codenames as Asdic (British) and Sonar (American), as well as Radar (American) or RDF (British), which uses radio echoes rather than sound echoes.”)

Questions 6-9: Summary Completion (Use ONE WORD ONLY) All the answers are in Paragraph D

6. phantom (in Paragraph D, line 6 and 7, the word PHANTOM is connected with arm or leg. Arm or leg is synonymous to limb. “like the referred pain in a phantom limb.”)

7. echoes/ obstacles (in Paragraph D, line 8 has a word “echoes” and line 9 has a word “obstacles”. In question 7 the keyword “perceives” means “to understand” which links the words echoes/obstacles. Thus, you can choose any of these two words as your answer.)

8. depth (in Paragraph D, line 10 an 11 says, “to measure the depth of the sea under a ship”. The word MEASURE is synonymous to CALCULATED in the question.)

keyword:

Calculated=measure

9. submarines (in Paragraph D, line 12 says, “for the detection of submarines.” The word DETECTION is synonymous to the word FINDING.”)

Questions 10-13: Filling in the blanks in sentences (Use NO MORE THAN TWO WORDS) All the answers are in Paragraph E

10. natural selection (in Paragraph E, line 2 and 3 says, “natural selection working on bats, had perfected the system tens of millions of years earlier;” which matches “long before the invention of radar)

11. radio waves/ echoes (in Paragraph E, line 4 says, “It is technically incorrect to talk about bat ‘radar’, since they do not use radio waves” This is a clear match with the question)

12. mathematical theories (in Paragraph E, line 5 and 6 says, underlying mathematical theories of radar and sonar are very similar; This is a clear match with the question)

13. zoologist (in Paragraph E, line 7, 8 and 9 says, “The American zoologist Donald Griffin, who was largely responsible for the discovery of sonar in bats, coined the term ‘echolocation’…”. A clear match with the question)
