The search was very involved and went far into her past, so it was very "extensive," or comprehensive and thorough.

Non-fiction stories are true stories that have happened, so you can describe them as being "realistic," which means accurately describing or portraying things as they actually are.

From the first sentence, we see that Jessica appears to have positive qualities except for her poor judgment with money. So, if we are looking for a type of sense that Jessica doesn't have, it must relate to finances, which is another word for money management. "Financial" sense is the term that we are looking for.

The correct answer is "identical," which means exactly the same in appearance. Since she was not able to tell the difference between the two backpacks, they both must be the same, or identical. "Colorful" could make sense, but two things that are each "colorful" do not necessarily look the same, so "identical" is the best correct answer.

The correct answer is "luxurious." "Luxurious" means extremely grand, expensive, or comfortable.

The correct answer is "sparse." "Sparse" in this sentence means empty or bare. Since Hannah was disappointed, we know that there must not have been any food for her to eat in her cabinets. The other words all mean the opposite of "bare."

"Ravenous" means very hungry. It makes sense that after months of sleeping and not eating anything, grizzly bears would awaken feeling starved. "Overjoyed," "friendly," and "calm" don't make sense in the sentence.

"Hazardous" means dangerous. Since this is a list of complaints, it makes sense that the workers would be upset about dangerous work conditions. "Harmless" is the opposite of "dangerous," "innocent" means lacking experience with the world and bad hings that happen in life, and "sociable" means liking to be with or talk to other people. The only word that works in the context of the sentence is "hazardous."

The student's family is worried he will exhaust himself, so "lethargic" cannot be the correct answer choice, as "lethargic" means feeling a lack of energy. "Lazy" cannot be the correct answer choice either. "Happy" has nothing to do with the context of the sentence, so "disciplined," a word that means dedicated and sticking to a set routine even when it is difficult, is the correct answer choice.

"Trepidatious" means very fearful or apprehensive. It would make sense that the athlete would feel fearful about skiing again after an accident that happened while skiing. Even if you don't know what "trepidatious" means, if you notice that "excited," "willing," and "thrilled" are all loose synonyms and none of those answers fits in the sentence, you should know to select "trepidatious."
