The sentence tells readers that the children "left the house in a state of disaster," so we can tell that we need to pick out a noun for the blank that means something like "a disaster." "Havoc" is a noun that means destruction or damage and it is the correct answer because it best fits the sentence's context. None of the answer choices make sense in the blank: "orderliness" means organization; "forgetfulness" means the tendency to be unable to remember things; and "plenitude" means a large amount of.

Since people became homeless as a result of the hurricane, the answer choice that makes the most sense would be negative and show that something bad happened. The answer choice that makes the most sense is "catastrophe," which means something that causes misfortune or a disaster. None of the other answer choices make sense in the blank: "abode" means home; "hoax" means practical joke in which something false is made to seem true; "fate" means destiny or kismet; and "secret" means a piece of information that one purposely does not tell others.

The word in the blank needs to describe that the car accident left two people dead. The answer choice that makes the most sense is "fatalities," which can mean people who were killed due to some specified event. None of the other answer choices make sense in the blank: "hoaxes" is are practical jokes that convince people that something false is true; a "ferries" are boats that carry people or items across a body of water; "incentives" are reasons for doing something; and "omens" are signs that something is going to happen.

Since Sarah "found it hard to recall when the pain began," we can infer that she must not know what caused her injury. The context clue in this sentence is noting that Sarah does not know the origin or "source" of the pain and when it began. This is opposite of the answer choice "ending." Also, "intensity" is the relative degree of something; "difficulty" is complexity; and "severity" is the degree to which something is severe in comparison to other things.

When people learn together, they often must cooperate. As a result, team is a good fit for this sentence because teams must work together and collaborate. 

We can infer that because the sentence refers to "climbers" who "placed a flag on [the mountain's] highest point" after they "made it all the way to the top," we need to pick out an answer choice that means something like "the top of a mountain." Neither "bottom" nor "valley" can be the correct answer, then, because each of those terms are antonyms of "top" and "mountain," respectively. "Summit," however, when used as a noun, means " the highest point of a hill or mountain," and because "summit" best fits the context of the sentence, "summit" is the correct answer.

We can infer that we need to pick out an answer choice that means something like "conditions," because the club "lost several members who did not meet the new conditions."

We can infer that we need to pick out a noun for the blank that means something like “a series of games.” So, while “game” may look like a potentially correct answer, “game” cannot be the correct answer because the sentence says that there were “many rounds of games.” “Tournament,” however, is a noun that can mean “a series of contests between many teams or players,” and because “tournament” best describes the series of basketball games that the sentence is discussing, “tournament” is the correct answer.
