How would you describe the effort of someone trying to fill a hole on the beach with sea water? It wouldn't work, would it?  Some good predictions could be pointless, ineffective, or unsuccessful. From our answer choices, inconclusive is close, but it means uncertain or unknown. However, the result of the boy's efforts is conclusive: it doesn't work. "Salutary" means healthy or wholesome, and while it might be salutary exercise to run back and forth on the beach, it certainly isn't a salutary effort to fill a hole with water. "Extensive" means far-reaching or comprehensive, so it doesn't fit the sense of the sentence. "Acclaimed" means widely praised, so it doesn't match our prediction. "Futile" means ineffective, useless, or doomed to failure.  That's our word!

Since no one is surprised that Darryl wants to try to break the world record for largest rubber-band ball, we can infer that he has a great many rubber bands at his disposal. So, we need to pick an adjective for the blank that means something like ample or great. While "ubiquitous" sounds like it could be the correct answer, "ubiquitous" actually means occurring or found everywhere, and if it were used in the sentence, it wouldn't actually describe the number of rubber bands in Darryl's possession. "Copious," on the other hand, means abundant and makes sense in the sentence's context, so "copious" is the correct answer.

The key expression in the main clause is the indication that the two people are on “friendly” terms. While one could say that this is an "average" or "acceptable" situation, it is even better described as being “amiable,” which means friendly. The word comes from the Latin for "friend," which is often found in the form “amicable” or even “amity,” the latter meaning a state of friendship.

The sentence does not indicate anything regarding the frequency or regularity of the young man’s use of nicknames for his elders; however, it is clear from the relative clause that his action is being described as not showing adequate respect to these parties; therefore, it is fair to say that he acted in a “flippant” manner. This does not merely mean that he acted lightheartedly, but also that he did so without showing the respect due in the given situation.

The key phrase in this sentence is “they were in fact carefully planned . . .” The contrast implied here is that the forest fires were not random blazes but instead were being carefully devised by the rangers. The introductory clause implies that they may have appeared to be unplanned. To this end, the word “sporadic” is the best option. While it might not be the best option in the abstract (meaning that we could likely find a better word if we had more than five to choose from), among our proposed answers, it alone signifies the sense of irregularity.

Since we know that the farmers did not plant anything on the land last year, we know that we're looking for an adjective that can refer to land and means something like "unused" or "unplanted." While "abstemious" sounds like a potential answer because it has to do with restraint, it refers to people and means "marked by restraint, especially in the consumption of food and alcohol," and is not an applicable word given the sentence's context - we need a word that refers to land. Alternatively, "fallow" specifically refers to land and means "plowed and left unseeded for a season or more; uncultivated," so it is the best answer choice.

Since we know that Carol began working extremely long days and losing sleep over her job, we can infer that one might describe her job as growing more "demanding," so we should pick out a word that means something like "demanding." While "grandiloquent" might sound like a potentially right answer because "grand" means "large or ambitious in scope or scale," "grandiloquent" actually means "pompous or extravagant in language, style, or manner, esp. in a way that is intended to impress," so it can't be the correct answer because it doesn't mean "demanding." "Exigent," however, means "pressing; demanding," so it is the correct answer.

Since we know from the sentence's context that Chelsea's sister talks a lot, we're looking for an adjective that has to do with speech, and specifically means "talkative." While "garbled" has to do with speech and messages, it means distorted and refers to speech itself, not the people who speak. Since "garrulous" means talkative, it is the correct answer.

Since we know that the detective missed several pieces of evidence during his examination, we can infer that we're looking for an adjective that means quick and careless. While "expeditious" does mean quick, it also means efficient. Since we can tell the detective wasn't efficient (he missed evidence!) we know that this word isn't the correct answer. "Cursory," on the other hand, means "quick" as well, and more specifically means hasty and not doing a thorough job. Because "cursory" means both quick and careless, it is the correct answer.

The best answer choice is "abstemious," which means restrained, since it indicates that the subject's father is refraining from certain dietary choices that may be negative.
