To "rectify" a situation is to repair it or make it right, generally when some problem has occurred. For example, if you failed to order enough pizza for the class party, you might rectify the situation by going out to get more. Of the answer choices given, "fix" is the only verb with a similar meaning. You may already know that to "compliment" another person is to say something nice about them, and the word structure of "undervalue" helps give away its meaning: to value, or appraise, an item at a lower amount than it is worth. Finally, "abdicate" means give up or renounce, and "perplex" means confuse.

To "adapt" is to "change" as circumstances change. "Advance" is to move forward; "compare" is to look at similarities; and "contrast" is to look at differences.

“Reign” means rule over a country as the leader of its monarchy, e.g. a king or queen. As a word it is usually used to describe the rule of kings or queens. So, "rule" is the correct answer. As for the other answer choices, "consider" means think about as a possibility; "damage" means cause harm to or mar the quality of; "decide" means pick or choose definitively between multiple options; and "drizzle" means to rain lightly ("rain" having an entirely different meaning from "reign," despite the two words being homophones); and "command" means lead or demand someone to do something using one's authority as force.

"Revert" means go back or return to a previous state, so "return" is the correct answer. "Soar" means rise or fly. "Smother" means cover or suffocate. "Consider" means think about. "Fulfill" means achieve, complete, or carry out.

The word "induce" means to cause something to happen. The best choice is "cause," as it is a part of the definition of "induce." 

"Proceed" means to go on, continue. To further help you, "purchase" means to buy; "overthrow" means to take power from someone; "banish" means to send away, to make illegal; "provide" means to give or supply something. 

"Revert" means to change back. To further help you, "retain" means keep; "illuminate" means make light up, brighten; "dampen" means to make a little wet; "drench" means to soak with water. 

“Advance” means continue or proceed, so "proceed" is the correct answer. The prefix "ad-" refers to a movement or change into or away from something as seen in “adulterate" (make something impure) and “adjunct” (an addition). None of the other answer choices are close in meaning to "advance": “detract” means take away from in terms of quality; “demonize” means vilify; “bewitch” means enchant; and “suspend” means pause.

The prefix "out-" generally means surpassing or exceeding, so if you “outperform” someone, you perform better than they do. So, "do better than" is the correct answer. To provide further help, “overwhelm” means overpower emotionally and “underwhelm” means disappoint, and “intrinsic” means basic, natural, or inherent.

To "hinder" someone is to put something in his or her way to prevent him or her from completing whatever it is he or she is working on. A "hindrance" is an obstacle blocking someone from completing his or her desired task as quickly as desired. The word "retard" means to slow down. For instance, you could say either, "I hindered the development of the new apartment building," or, "I retarded the developement of the new apartment building."
