We know that the science teacher mixed the wrong chemicals together AND that this caused the school to be evacuated. We can infer, then, that the fumes were bad for people. The only answer that fits this description is "noxious," meaning harmful or dangerous.

Since Robbie was not following school rules by using his telephone in class, we can infer that the principal would either do something to force Robbie to follow the rules, or punish him in some way. "Confiscate" is a verb that means to surrender something to a legal authority. 

Since Tom and Sam were disgusted at the discovery, we can infer that they did not get what they thought they were paying for. "Counterfeit" means fake or false. "Authentic" and "genuine" are both antonyms to "counterfeit." "Disheveled" refers to a messy appearance. "Ingenious" describes a very clever idea or person.

"Wedding invitations" are paper products, so Ariana is going to a store that sells paper products. "Florists" sell flowers, "jewelry" stores sell jewelry, and an "accessory," in this instance, is something that is an extra item for an outfit. For instance, a scarf might be an accessory. This leaves "stationery" and "stationary." "Stationery," with an "e" refers to paper products, while "stationary," with an "a" refers to something that doesn't move.

The key words in this sentence are "determined" and "despite." These words indicate that Li is facing an obstacle. We can infer that an obstacle to finishing a race would be poor weather conditions. "Adverse" means not ideal, which fits the sentence. "Averse" means against and "inverse" means opposite.

It's likely Maria feels misunderstood by her friends who wish she "fit in" and not be herself. "Entertained" and "amused" are similar in meaning, and do not describe how Maria feels in a situation in which she's pressured to be like others. Finally, far from "praising" her, Maria's friends are putting her under significant pressure.

The word "while" at the beginning of the sentence signals the presence of opposition between two or more elements in this sentence. In this case, there are two friends who are happy about their team's win, while another friend who is not. Given that Jake is unhappy about how the team reached their goal of winning, he's likely conflicted-- probably torn about cheering with his friends and teammates, but unable to fully engage due to their act of cheating. Therefore, the best answer is "happy" and "conflicted." The other pairs do not fully express the strong oppostion that presents itself in the scenario the sentence describes--for one "elated" and "euphoric" are very close in meaning (not opposites), as well as, "sad" and "sullen" (both are very close). "Satisfied" and "wasteful" are not opposites, and a cheating scandal does not make you feel "wasteful" as much as ethically at odds. The same with "remorseful" and "content;" they are not opposites and do not fit the emotions described in the sentence.

Identify the key transition term in the sentence: "although." It calls forth an opposition; in this case, between scientists' negative reaction to some results and their aproval of the part of the method that was used to produce them. You are looking for a word in the negative slot, that would allow you to say that the scientists did not agree with the results. "Corrected," "consented," and "confirmed" are all positive words; and "disturbed" is an awkward choice to describe disagreement, so therefore you can eliminate it. The scientists disputed the results, despite agreeing with the experiment. 

To "settle" for something means to become satisfied with it after your first option becomes unavailable or unattainable. Since Tania and her mom really want a dog, but decide they can't care for it, they "settle" for a cat. The other options do not adequately convey the idea of choosing your second best option.

The speaker of this sentence is an immigrant living in America. Based on the context of this sentence you know that the correct answer must mean something like removed from the country for committing a crime. The correct answer is therefore "deported." To provide further help, "daunted" means frightened, intimidated; "exhumed" means dug up, as in dug up a corpse; "infected" means made sick; "reinstated" means brought back, allowed to rejoin something.
