Question

question 1
this article is mainly about _______.
a. the history of our closest genetic kin, chimpanzees and bonobos
b. a unique facial feature in humans that has puzzled scientists
c. a disagreement about the development of jaws for chewing
d. the history of our extinct human relatives, the neanderthals

Explanation:

To solve this, we analyze each option:

• Option A: Focuses on chimpanzees/bonobos’ history. But the question is about an article’s main topic—without the article, we assume typical contexts. However, if the article is about human facial features (common in such questions), this is off - topic.
• Option B: A unique human facial feature puzzling scientists. This is a common topic in articles about human evolution/anatomy, and it’s a plausible main idea.
• Option C: Disagreement about jaw development for chewing. This is too narrow (jaw development is a specific aspect, less likely to be a main topic unless the article is solely about jaws).
• Option D: History of Neanderthals. Neanderthals are extinct human relatives, but if the article is about a human facial feature, this is off - topic.

Answer:

B. a unique facial feature in humans that has puzzled scientists
