Due to her quirky way of dressing and the fact that she dances around the classroom, the English teacher is best described as eccentric or unconventional.

The best word to describe the dishes that are typically eaten at an American Thanksgiving dinner is conventional; certain dishes are conventionally or normally served.

We can infer from the sentence's description of the movie's plot that it is probably gory, or "involves a lot of violence and bloodshed." While we can describe the moviegoers and theatre staff as "unlucky," "unlucky" does not describe the plot of the movie itself, so it cannot be the correct answer. The best answer is "gruesome," an adjective that means "causing repulsion or horror; grisly," or "extremely unpleasant."

We can infer that we need to pick out an adjective that means something like "special" because the sandwich our word will describe comes with extra toppings compared to the "regular sandwich." "Hungry" might look like a potentially correct answer because of the sentence's culinary context, but since it wouldn't make sense to describe a sandwich as being "hungry," "hungry" cannot be the correct answer. "Deluxe," however, is an adjective that means "luxurious or sumptuous; of a superior kind," and because "deluxe" best describes the sandwich that comes with extra toppings, "deluxe" is the correct answer.

We can infer that whichever adjective goes in the blank, it needs to describe the mansion described when the sentence says, "its windows were broken and dusty, its roof missing most of its tiles, and it looked as if the entire building might come crashing down around anyone who entered." So, we need to pick out an adjective that means something like "run-down" to describe the building. "Well-maintained," then, cannot be the correct answer because the building is clearly not well-maintained if Harry is concerned about it "[coming] crashing down." "Derelict," however, is an adjective that can mean "in a very poor condition as a result of disuse and neglect," and because "derelict" best describes the building described in the sentence, "derelict" is the correct answer.

In this case, "versatile" means multitalented or able to do many things. If Karen has extensive training in several different genres of dance, she is a versatile dancer. While she might be a gifted dancer, that answer choice implies innate talent rather than the versatility extensive training would provide.

The sentence is expressing a contrast. It is surprising that Gregory is calm during a set of circumstances that apparently would be a cause for him not to be calm. This means that he was often—even in small things—agitated or nervous. It does not make sense to say that he was somewhat raging. A "raging" person is someone who is very angry; it is not a matter of many degrees. The other options do not provide an adequate contrast to the calmness. Therefore, the option "agitated" is the best.

From the description of William, it is safe to say that he does not spend much time thinking about other people. In almost every aspect of social interactions, he is self-centered and causes inconvenience for others. Another way to describe this is to say that he does not even consider the other people at all. Therefore, we can fairly say that he is "inconsiderate." While he might be called "greedy" (for not paying) or "boisterous" (for talking over others), the description "inconsiderate" best describes the complete nexus of bad character traits that he shows.
