When you read carefully and rely on context clues, you are..

The answer is:

d. making educated guesses as to the meaning of difficult words.?

Context clues are hints that an author provides to help illustrate a difficult or unusual word. They may appear within the same sentence or in a nearby sentence in relation to the word they refer to. Besides, an educated guess indicates an assumption based on knowledge and experience, which is therefore likely to be correct. As a result, context clues aids readers to make inferences about unknown vocabulary.

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 ! : )
