Suppose we are given three pitchers of water, of sizes 10 quarts, 7 quarts, and 4 quarts. initially the 10-quart pitcher is full and the other two empty. we can pour water from one pitcher into another, pouring until the receiving pitcher is full or the pouring pitcher is empty. is there a way to pour among pitchers to obtain exactly 2 quarts in the 7- or 4-quart pitcher? if so, find a minimal sequence of pourings to get 2 quarts in the 7-quart or 4-quart pitcher

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."

the correct answer is d. a discussion of specific uses of alliteration

when you are critiquing or evaluating a poem, you will mostly pay attention to the theme, as well as figures of speech and rhythm. alliteration is a figure of speech where consonants are repeated in neighboring words - and it is important for analysis of sound and rhythm, which is why it might appear in the evaluation of that poem.
