Question

Select the correct option:

Each of the datasets-------------been anonymized before release.

• A. have
• B. has
• C. are
• D. were

Answer 1

Answer:

B. has

• The sentence structure is: "Each of the datasets [has] been anonymized..." The subject of the sentence is "Each", which is a singular distributive pronoun and always takes a singular verb (has), regardless of the plural noun ("datasets") that follows it.
