Explanation:

When you get questions like this one, the thing that would help you the most is a dictionary. A dictionary is an alphabetically arranged listing of words that contains various information about them, such as their definition, examples, origin, and pronunciation.

The sentence you were given is missing a noun and an adjective. This can help you eliminate all words that belong to other parts of speech. Context can help us determine which options are correct as well.

You were given two nouns: supplement and diversity. Supplement doesn't fit (there is no such thing as a supplement of courses), which leaves us with diversity.

You were given two adjectives as well: moderate and tentative. Tentative doesn't fit (college prices are always known), which means that moderate is the correct answer.

you need to explain that more, your grammer just needs to be close to perfect.

i think it's either 'to expose the corruption of the communists in russia', or 'to criticize animal brutality by communists in russia.'  

hope this ! : )
