Select the most appropriate option to fill in the blank.
She hardly works on weekends, ______?

To choose the correct question tag, we need to analyze the structure and meaning of the statement:
"She hardly works on weekends, ______?"

1. Identify the verb and tense: The verb in the main clause is "works", which is in the simple present tense. For the simple present tense, we use the auxiliary verb "do" or "does" in the question tag. Since the subject is "She", the corresponding auxiliary verb is "does".

2. Determine the polarity (positive or negative): The sentence contains the word "hardly". "Hardly" is a negative adverb, which gives the entire statement a negative meaning (meaning she almost never works). According to the rules of question tags, a negative statement must be followed by a positive question tag.

3. Form the tag: Combining the positive auxiliary verb "does" and the pronoun "she", we get "does she".

Therefore, the most appropriate option to fill in the blank is does she.
