C. reality : delusion

Explanation:

In order to complete the analogy, we must first discover what the relationship between the two given words is.

- A fact is something that is absolutely true, backed by evidence

- A fiction is something that is made up, so it's not necessarily true

Ah, now we see: these two words are antonyms; in other words, they're opposites of each other, so we want to find a pair that is also made up of antonyms.

A: unreal : delusion

- unreal: this means something that isn't reality

- delusion: this is a false belief

These two words aren't really synonyms, but they're not antonyms, either, so eliminate.

B: disbelief : delusion

- disbelief: not believing something

- delusion: false belief

There isn't a really clear relationship between these two words, but we can definitely say that they're not antonyms, either, so eliminate.

C: reality : delusion

- reality: something that is true

- delusion: false belief

Ah, now we can see that these two are quite opposite, so this is the answer.

D: fantasy : delusion

- fantasy: a made-up, unreal world

- delusion: false belief

These aren't opposites either, so eliminate.

The answer is thus C.

b. brooks wrote about the same type of neighborhood in which she grew up.
