Question

Select the correct option: Only after a decade of fieldwork fully grasp the dialect's nuances.

• A. she had
• B. did she
• C. had she
• D. she did

Answer 1

Answer:

B. did she

• This sentence requires adverbial inversion. • When a sentence begins with a restrictive time phrase like "Only after a decade of fieldwork...", the subject and the auxiliary verb must invert. • The structure becomes: Adverbial phrase + auxiliary verb (did) + subject (she) + base verb (fully grasp).
