The love of English culture makes someone “Anglophile.” "Anglo-" means English, and "-phile" means lover of. “Philosophical” means lover of wisdom and deep thinking or having to do with figuring out large truths about the world, often by deduction; “whimsical” means quirky, silly, and unusual; “irrational” means not rational, or in other words, based on illogical beliefs; and “jovial” means cheerful and merry.

Someone who is inconsistent and always changing his or her mind is called “fickle.” “Reckless” means behaving and acting without caution or dangerous; “constant” means not changing; “persistent” means dedicated or willing to keep trying to make something work; and “sustained” means long-lasting.

The answer choice here must describe a rude and grumpy old man who is unkind to children. The correct answer is therefore “cantankerous,” which means grumpy. “Gregarious” means sociable and friendly; “garrulous” means talkative; “monotonous” means boring and repetitive; and “banal” means dull.

While this lake was likely "frigid" (extremely cold), that in itself would not eliminate the need to purify its water. Both "adulterated" and "opaque" water would suggest water that was in desperate need of purification. "Pristine" comes from a Latin word that refers to something's earlier state, before it has been contaminated. Thus, this word that means clean and pure is the best fit here.

Someone who is motionless could be described as “inert.” Because the old woman has not moved for several days, she could be called “inert.” “Dynamic” means the opposite of “inert”; it means full of energy and active; “literate” means able to read; “rakish” means charming, dashing, and handsome; “presumptuous” means overconfident and making arrogant assumptions.

“Sagacious” is another word for wise, and someone who is full of wisdom is called “sage.” As for the other answer choices, “hostile” means aggressive; “bellicose” means aggressive and warlike; “abrasive” means rude and aggressive; and “rancorous” means bitter and hateful. These words are all loose synonyms.

Because the subject ended up without friends, but was trying to be cool, we might infer he was acting distant, detached, and disinterested in others. This is the meaning of the word “aloof.” “Gregarious,” “outgoing,” “convivial,” and “genial” all means sociable and friendly. They are antonyms of “aloof."

It makes sense that you would feel safe if your house was next to a police station and a hospital, so the correct answer is “adjacent.” “Detached” means not connected to or not attached to; “incongruous” means inappropriate or out of place; “lenient” means tolerant or not strict; and “opulent” means luxurious or rich and showy.

Seeing as the parents criticized the teachers for not enforcing discipline and allowing the students to be unruly, it makes sense that the teachers were criticized for being too “lenient.” “Lenient” means not strict, not enforcing the rules or tolerant. “Intolerant” means not tolerant, or in other words, not patient or accepting; “severe” means extreme or intense; “supreme” means best or foremost; and “grave” means somber, sad, and serious.

When something occurs by chance, it can be called “serendipitous.” “Unfortunate” means not fortunate or unlucky; “demonstrative” means showing something by demonstration or showing emotion; “incredulous” means disbelieving or not accepting; and “appalling” means dreadful, disgusting, or outrageously bad.
