A. swift
B. aggressive
C. cumbersome
D. conspicuous
E. raucous

Correct Answer: D

Explanation:

Skill: Understanding the content, form, and function of sentences

Explanation for Correct Answer D :

Choice (D) is correct. "Conspicuous" means obvious or attracting attention. If one were to insert this term into the text, the sentence would read "Male ostriches are extremely conspicuous: they can be perceived by the human eye at a distance of 900 meters." The information following the colon provides an explanation of the missing term. It makes sense to call an animal large enough to be seen at a distance of 900 meters "conspicuous."

Explanation for Incorrect Answer A :

Choice (A) is incorrect. "Swift" means capable of moving very fast. If one were to insert this term into the text, the sentence would read "Male ostriches are extremely swift: they can be perceived by the human eye at a distance of 900 meters." A "swift" animal is not necessarily noticeable from far away.

Explanation for Incorrect Answer B :

Choice (B) is incorrect. "Aggressive" means hostile or combative. If one were to insert this term into the text, the sentence would read "Male ostriches are extremely aggressive: they can be perceived by the human eye at a distance of 900 meters." "Aggressiveness" does not contribute to a human's ability to see an ostrich from 900 meters away.

Explanation for Incorrect Answer C :

Choice (C) is incorrect. "Cumbersome" means clumsy or unwieldy. If one were to insert this term into the text, the sentence would read "Male ostriches are extremely cumbersome: they can be perceived by the human eye at a distance of 900 meters." The male ostrich may be clumsy, but this trait is not related to its being visible from far away.

Explanation for Incorrect Answer E :

Choice (E) is incorrect. "Raucous" means boisterously disorderly. If one were to insert this term into the text, the sentence would read "Male ostriches are extremely raucous: they can be perceived by the human eye at a distance of 900 meters." The ostrich's temperament has nothing to do with the fact that it can be seen from far away.
