The answer to 1 is imagery because the description helps us to better see the thrush through its use of adjectives.
The answer to 2 is sight, because we see gray rather than feel gray.
The answer for 3 is "is" because "dictionary" is a singular noun, not a plural noun. There is only one dictionary.
The answer to 4 is "was" because "tourist" is a singular noun, not a plural noun. There is only one tourist.
The answer to 5 is "was" because there is only one Statue of Liberty. It is a singular noun.
Remember, the general rule for singular/plural nouns is that plural nouns are usually attached with an "s" at the end. Although there are exceptions, it helps with most nouns.
