Claim: Classes on parenting should be offered in public schools, and so should classes on Chinese.
What makes this a weak claim for an argumentative research paper?
A. The topic has a limited audience.
B. The statement is too short.
C. The author doesn't state a position.
D. The sentence has too many ideas.
Of the options given, "D" is the most suitable. On the surface, the ideas appear incongruous: what does learning Chinese have to do with parenting? In reality, one could most certainly write an essay explaining that thesis statement.
