"Contrary" is an adjective that means "opposite in nature, direction, or meaning," so we need to pick out an adjective that means something like "opposite." "Similar" cannot be the correct answer because "similar" is an antonym of "opposite," but because "opposite" is one of the answer choices, and the answer choice closest in meaning to "contrary," "opposite" is the correct answer.

Deficient means lacking or missing something. To further help you, courteous means polite; obsolete means no longer useful or out of date; negative means bad; positive means good.

"Sublime" means awe-inspiring or overwhelmingly magnificent. "Magnificent" is the best match because it means impressive or spectacular.

“Contrary” is similar in meaning to "opposing." It is commonly heard in the expression, “on the contrary,” meaning in opposition to what someone is saying. To provide further help, “encouraging” means offering support; “manipulating” means controlling or tricking; “diabolical” means evil. You could say that someone who is always trying to “manipulate” others is very “diabolical.”

The word "equivalent" has a base that is certainly quite familiar to you: "equ-" as used in "equal," "equally," and so forth. When two things are "equivalent," they are the same, like 2 and 1 + 1.  Equivalence indicates a greater degree of correspondence than mere similarity. Two people might be similar in appearance, but equivalence is strict equality. Therefore, the best option among those given is "identical," which indicates such strict equivalence.

"Bizarre" means strange or unusual. This word is often used to describe appearances. "Common" and "familiar," which mean usual or encountered often, refer to things that you see often or have seen before, and are opposites of the answer we want. Finally, "crowded" might be used to describe an event packed with lots of people.

"Detrimental" means likely to cause injury or damage; therefore, "damaging" is the word that most closely matches the definition of "detrimental." "Liberating," which means freeing, and "seldom," which means rarely, are unrelated to the definition, as is "possessively."

"Despicable" means to be loathsome, or deserving of hate. The word that most closely takes on this meaning is "terrible," which is something that is very bad. While both "ugly" (repulsive-looking) and "terrible" are negative terms, something that is "ugly" is not necessarily "despicable." Similarly, something that is "dark" or "serious" would also not be "despicable."

Something that is "derogatory" is disrespectful and offensive to another person. Something that is "insulting" puts down another person. Given how similar these meanings are, these words are synonyms.

For this question, you just need to be careful about the intensity of the word. Something that is "frigid" is very cold. Therefore, the best option is "freezing", for this word describes the coldest condition among the options given to you. Always find the word that is closest to the intensity indicated by your word.
