What is the tense of the underlined verb?

i taught myself the capitals of all the states yesterday.

a.
past

b.
past perfect

c.
present

d.
future

The correct answer is A, past.

The verb taught is a past tense verb or a past participle. This automatically excludes C, present and D, future.

The choice is now between A and B. To form a past perfect you need the verb "to have" in the past, "had". Because there isn't an auxiliary verb here, it is in the past. It also helps to look at the word "yesterday", which shows us this is a past action but not that far in the past to be called a "past perfect".

The correct answer is A. Past

I took the quiz :)

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
