","stem_html":"The sentence "The cat sat on the mat, watching the birds." is grammatically correct, but it lacks a clear subject. Which of the following is the BEST way to rewrite the sentence to include a clear subject?
","rationale_html":"Choice B is the best option because it adds a clear subject to the sentence while maintaining the original meaning. The phrase "sitting on the mat" modifies the subject "The cat." Choice A creates a dependent clause and doesn't have a clear subject. Choice C also creates a dependent clause and doesn't have a clear subject. Choice D is redundant and unnecessary. The pronoun "it" is unnecessary, and it creates an awkward sentence structure.
