The sentence tells us that the organization is of a certain type because it is active in many different nations, so this means the correct answer is “international.” The prefix "inter" can mean between, as in the words "intercontinental" and "intercom." So, "international" means between nations. To provide further help, “permissive” means accepting, and “obstructive” means getting in the way.

By reading the sentence, we can tell that Jim is "suspicious" because his wife is acting in an unusual, "secretive" way that suggests she is keeping something from him. We are looking for a word that helps to further describe the suspicious, secretive way that she is acting. Thus, the blank should contain a word like "mysterious," "quiet," or "unable to be interpreted," since Jim "can't tell why" she is acting this way. Thus, "enigmatic" is the best answer because it means mysterious, inscrutable or baffling. The other word choices can be eliminated since they do not work well in the sentence: "pretentious" means arrogant or cocky; "reverent" means respectful; and "boisterous" means loud and rambunctious.

We need to pick out an answer choice that is an adverb and means something like "knowingly” or "purposely" because the sentence tells us that Joy snuck out of the house and betrayed her dad's trust, which takes planning and intentional action. The word "betrayed" gives us a hint that Joy went against a rule or moral that her father expected her to follow. "Deliberately" is the best choice, since it means purposely or intentionally. This best conveys the idea that Joy snuck out of the house on purpose, which betrayed her father's trust and upset him. None of the other answer choices make sense in the blank: "reluctantly" means hesitantly; "inadvertently" means unintentionally; and "subordinately" means accidentally. 

By reading the sentence, we can infer that the "new and improved floor plans" made it possible for the architects to reach their goal of constructing the office building by March. Thus, we know that the blank should contain a word similar to "possible." The correct answer is "plausible," since it means possible, imaginable or feasible. The other words do not fit in the context of the sentence: "ambivalent" means undecided or unsure; "desiccated" means dried up; and "diffident" means shy.

The general idea in this sentence is that Amanda was able to overcome problems in an intelligent manner, even when little was at hand. When someone is "resourceful," such a person is able to use available things—resources—in a very shrewd manner.

The sentence concentrates on small children's abilities to destroy things. Therefore, the contrast implied is between "fragile" and the sentence's blank. Do not be tempted by options like "dull" or "blunt" merely because the parents of young children often have to make their houses safe. The contrast for "fragile" is strong or not easily broken. The word "durable" means just that.

A quick glance at this sentence tells us that we are looking for an adjective that describes a minivan. More specifically, it describes the minivan that Mr. Williams wants to buy. The only other information we are given tells us that Mr. Williams wants a car that will be long-lasting instead of falling apart immediately. The answer choice that accurately describes this quality is "durable," which refers to a product that remains in a good condition over time.

Because the teacher struggled to grade the hand-written essays, we can assume that the handwriting on them was hard to read. The answer choice that most closely resembles this definition is “illegible,” which means unable to be read. To provide further help, “serene” means peaceful; “passive” means not aggressive or not taking the lead; “crafty” means sneaky, manipulative, and clever; “brittle” means easily broken.

Since the railroad runs all the way across the continent, it can be called “transcontinental.” The prefix "trans-" means across. To provide further help, “propulsion” is force that causes movement to occur; “submersible” means able to be covered with water; “humanitarian” means compassionate and helpful towards one’s fellow man.

The description of the witness suggests that he was visibly nervous, likely because he was lying. In other words, his behavior made him seem not believable. The best answer choice is “credible,” which is a synonym of "believable." To provide further help, “incredible” means great, brilliant; “intelligent” means smart; “devout” means very religious; “praiseworthy” means laudable, deserving of praise.
