Mark for Review

Which choice most logically completes the text?

mosquitoes without damage to their odor receptors are more capable of finding humans than those with damage.

like mice, fruit flies, and humans, individual mosquitoes with damage to particular receptors will be unable to detect certain odors.

researchers cannot assume that mosquitoes have the same correlation between receptors and the ability to sense certain odors that mice, fruit flies, and humans have.

researchers can assume that interfering with mosquitoes' odor receptors is a potential way to prevent mosquitoes from feeding on humans.

Correct Answer: C

Your Answer:

Explanation

This is a Conclusions question as it asks for an answer that logically completes the text. Read the text and highlight the main ideas. The focus of the text is on a receptor related to odor. The first sentence states that eliminating that receptor…results in the inability to smell that odor. The second sentence states that mosquitoes modified to lack the receptor for smelling blood would be unable to find humans, but the third sentence says they were still able to find humans. Therefore, a logical conclusion to the text should make some claim about how mosquitoes may be different from other animals.

(A) is wrong because no comparison between mosquitoes without damage and those with damage is made in the text.
(B) and (D) are wrong because they are the Opposite of what is stated in the text: in both cases, mosquitoes with damage to their odor receptors were still able to find humans, so there is no evidence they could not detect certain odors or would be prevented from feeding.
(C) is correct because it indicates that mosquitoes may not have the same correlation between receptors and the ability to sense certain odors that other animals do.
