Answer #1

The dependent t-test can be used to test either a "change" or a "difference" in means between two related groups, but not both at the same time(here a vocabulary test at the beginning of the school year and at the end of the school year.). Whether you are measuring a "change" or "difference" between the means of the two related groups depends on your study design.

d.

Repeated measures t-test

is the correct option.
