“Complete,” when used as a verb, means conclude or "finish." As for the other answer choices, “concede” means give up or admit that an opposing point is correct; “recede” means back away; “desire” means want; and "function" means work as expected to.

"Dis-" is a negative prefix that often means not, and "rupt" is a Latin root that means to break—think of English words like "rupture" (a tear or break in something or to tear or break) and "interruption" (the act of breaking into someone else's conversation or something that breaks into someone else's planed activity). Given this, it makes sense that "disrupt" means to break the progress something, or to "disturb," a verb that can mean to interrupt the progress of. 

As for the other answer choices, “discover” means find; “dismay” means sadden and disappoint; “disparage” means make fun of and say that that person or thing is not worth anything; and "displease" means to anger or annoy.

To “conclude” means to bring to a close, to end, or to "finish." “Commence” means begin, and “suspend” means pause or stop.

"Preserve" means to save or to keep safe. To further help you, "evade" means to get out of the way of; "escalate" means make worse or make more severe; "portray" means show.

The verb "ail" means hurt. The best choice is "hurt," as it a part of the definition of "ail." Considering the other choices, "pale" means having light or muted colors, "fix" means repair, and a "pail" is a bucket.

If you "require" something, then you need it, so "need" is the correct answer. To help you, the other four answer choices are all synonyms of one another; "abhor," "detest," and "despise" are all verbs that mean extremely dislike.

"Manipulate" means control something or someone to serve one’s purpose. "Influence" is the best choice, because "influence" means change or affect someone or something when used as a verb.

The word "deteriorate" describes something that is becoming worse. For instance, we might say, "Her health was deteriorating for some time before she died," meaning that her health was getting worse before she died. Several of the options are trying to confuse you into thinking that "deteriorate" is the same as "determine." (These are "learn" and "discover".) The obvious correct answer is "worsen."

Your synonym must match the intensity of your word if it can. When we "exterminate" something, we completely destroy it. This word might have been used by your parents if your house has ever had a lot of ants (or other bugs) in it. An "exterminator" is someone who completely kills the bugs in the house—or at least tries to! The word does not mean to poison. It means to destroy completely. Thus, the best option is "eradicate", which means to destroy completely.

The word "deplete" is not the same as "delete." They are somewhat alike, but they are not the same. When something is "depleted," it is emptied out. For example, we could say, "The group depleted the stores of food," meaning that they used them up. The word "consume" does not merely mean to eat. It can also mean to use up. Therefore, it is quite a good option for this question!
