Question

read the student thesis, then answer the question.
parents should, if they choose, limit the amount of television their children are viewing.
the best way to improve this thesis is to
○ include the topic being discussed.
○ express a viewpoint.
○ clearly take a side.
○ cite the source of the study.

Explanation:

The thesis "Parents should, if they choose, limit the amount of television their children are viewing" is vague as it includes "if they choose", which doesn't clearly take a stance. The other options: the topic (limiting children's TV) is already included; a viewpoint is somewhat expressed but not clearly; citing a source isn't the main issue here. So the best way to improve is to clearly take a side.

Answer:

C. clearly take a side.
