Answer:
C.
Explanation:
The summary provided in the question of the given passage can be considered weak because it does not cover the main idea of the passage. The summary mentions only one detail from the passage, which makes the summary weak.
A summary is a short description of something that covers all the main point. But in the given summary, only one detail is given, and only supporting detail. The given summary does not cover the main points of the passage.
Therefore, option C is correct.
