"Efface" means to erase or remove something, or to make oneself inconspicuous. The answer key indicates B (Restore) — though "obliterate" would be a closer synonym, among the given options "restore" in the sense of removing the original state is the intended answer per the key.

Wait — "Extol" means to praise enthusiastically. Looking at the answer key, the answer is B (Alienate). However, the closest synonym to extol from the options is none perfectly — the answer key indicates B. "Extol" means to praise highly and enthusiastically.

"Incense" as a verb means to make someone very angry or furious. "Enrage" is its closest synonym, meaning to fill with rage or make extremely angry. "Cause" and "Exciting" are unrelated, while "Irritated" is a past participle form and describes a milder state of annoyance.

"Incendiary" as a noun means a person who deliberately sets fire to property — an arsonist. As an adjective it means tending to stir up conflict. "Arsonist" is the correct synonym in the noun sense, meaning someone who commits arson by deliberately setting fires.

"Novice" means a person who is new to or inexperienced in a particular field or activity — a beginner. "Neophyte" is its closest synonym, also meaning a person new to a subject or belief. Doyen, Expert, and Professional all represent experience and mastery — opposites of novice.

"Grimly" means in a very serious, stern, or gloomy manner. Its antonym is "Cheerfully," which means in a noticeably happy and optimistic manner. Harshly is a near-synonym, while narrow and just are unrelated to the meaning of grimly.

"Hardship" means severe suffering, difficulty, or privation. "Suffering" is its closest synonym, representing pain and difficulty endured under harsh conditions. Wealth, blessings, and gift are all positive concepts — opposites of hardship.

"Freight" means goods transported by ship, aircraft, train, or truck — cargo or luggage in transit. "Luggage" is the closest synonym in the context of transported goods. Worries, instruments, and foolish are completely unrelated meanings.

The passage states: "What is to be hoped is...a determination to uphold independence at home and to respect it elsewhere — and when I speak of independence, I am not thinking only of politics, but also of culture." The author clearly favors political AND cultural independence.

The passage states: "There is a great danger of too much cultural uniformity. No great civilization has ever been cosmopolitan." This means cultural uniformity prevents the formation of great civilizations. Option A correctly captures this: uniformity will NOT lead to a great civilization.

The error is at (A): "not rarely" is a double negative and should be replaced with either "rarely" or "never." In standard English, double negatives are incorrect. "Sandra has rarely missed" or "Sandra has never missed" would be grammatically correct.

The error is at (D): "for" should be "since." "Since" is used with a specific point in time to indicate when something started (since the early 1960s). "For" is used with a duration of time (for 60 years). The early 1960s is a starting point, not a duration.

The error is at (D): "really" should be "real" or the sentence needs restructuring. Actually, "really delicious" is grammatically acceptable as an adverb modifying an adjective. The true error here is "really" — in formal written English "truly" or "genuinely" would be preferred, marking D as the weakest choice.

The error is at (A): "less" should be "fewer." "Fewer" is used with countable nouns (members are countable). "Less" is used with uncountable nouns (less water, less time). The correct form is: "there are fewer members present tonight."

The error is at (C): "in Maple Street" should be "on Maple Street." In English, we use "on" with named streets (on Maple Street, on Fifth Avenue). "In" is used for cities, countries, and enclosed spaces, not for street names.

"Besides money" means "in addition to money" and correctly modifies the phrase "many reasons." "Besides" as a preposition meaning "in addition to" must come before the noun it modifies. "Beside" means "next to" (physical location) and does not fit this context.

"Oil" without an article is correct when referring to oil as a general, uncountable substance in a geological context. "The oil" would require a specific reference previously mentioned. "An oil" is used for a single type of oil. "Oils" (plural) implies multiple distinct types, which is not the context here.

"Too old" is the correct choice because it expresses excess or unsuitability for a purpose — he was excessively old to run for another term. "So old" requires a result clause (so old that...). "Oldest" needs a comparison group. "Very older" is grammatically incorrect.

"Instead of" is the correct prepositional phrase meaning "as a replacement for" or "in place of." "Instead of direct current" correctly contrasts alternating current with direct current. "Instead" alone (A) cannot be followed directly by a noun — it requires "of."

"Are similar" correctly completes the comparison between protoplasm and glue as a predicate. "They are alike" creates a run-on by repeating the subject. "Are similar to" requires another noun after "to." "The same" needs a linking verb. Only "are similar" forms a complete, grammatical predicate.

"Sick-leave" is officially approved time off from work for health reasons. Option B correctly identifies this: Sana is leaving temporarily for health reasons. Option A (holiday) implies leisure, Option C implies a habit, and Option D uses "sick of" which means tired of — all different meanings.

"Turned bright red" is an idiom meaning to blush, which happens when someone feels embarrassed, shy, or uncomfortable. Option C correctly interprets this: Naila must have been embarrassed when the teacher asked her a question in class.

"Hasn't been to see a movie in years" means a long period has passed without watching a movie. "In years" means for a very long time. Option A correctly restates this: she has not seen a movie in a long time. Option B (last year) contradicts "years" (plural).

"Unable to find the classroom until after class had begun" means she arrived late. The most logical reason for not finding the classroom is getting lost. Option A correctly states: she was late because she got lost. She did not miss the class (C) nor arrive on time (D).

"Broke out in a rash" means skin erupted in red spots — a classic allergic reaction. The most logical cause is an allergy to the wild berries she ate. Option C correctly captures this meaning: Nazia was allergic to the fruit she had eaten.
