Explanation:
this is a hint
your answer would be B. themselves
Answer:
I think the answer is B. (Sonar systems allow animals to "see" using their ears.)
Explanation:
By process of elimination:
A. is incorrect because this statement is only indicated in lines 4 to 7. It is no way the central point of the paragraph.
C. is incorrect because; while the passage mentions that bats are nocturnal, It gives no indication as to whether it (the bat) is also small. Nevertheless, the passage also talks about whales which are the literal opposite of small.
D. is a very tricky option because it is actually implied in the paragraph. Personally, I think D is also a correct answer but my first choice is still B. because of the final statement on human application of sonar systems.
