To vary the sentence structure, which one of the answer choices should you insert into the blank space? anna is an exceptional young girl. anna does any job that needs to be done
a. have you noticed how hard she works?
b. anna works hard every day of her life.
c. anna is always working hard at home.
d. anna is a hardworking and versatile person.

A. Have you noticed how hard she works?

Explanation:

Every clause in the sentence seems to start as a independent clause, with an explicit subject (Anna) followed by a predicate. In order to vary this structure, an option that does not contain an explicit subject needs to be chosen - this is option A.

Option A does not mention Anna as the subject explicitly - unlike the other options. The subject is addressed as a singular second person (You).
