TOEFL Academic Vocabulary in Context

Question 1

In the sentence "The scientist's hypothesis was subsequently corroborated by three independent studies," the word "corroborated" most nearly means:

Accepted Answer

confirmed

Answer

"Corroborated" means confirmed or supported by evidence. The context — independent studies backing a hypothesis — makes "confirmed" the correct choice. "Disproven" and "challenged" are opposites of what the sentence implies.

Question 2

Read the passage: "Despite the ostensibly simple design of the experiment, the underlying mechanisms proved remarkably complex." What does "ostensibly" mean?

Accepted Answer

apparently

Answer

"Ostensibly" means apparently or seemingly — something that appears to be true on the surface but may not be. The contrast with "proved remarkably complex" signals that the simplicity was only superficial.

Question 3

Which sentence uses the word "proliferate" correctly in an academic context?

Accepted Answer

The number of online learning platforms has proliferated rapidly in recent years.

Answer

"Proliferate" means to increase rapidly in number or spread widely. The second sentence correctly uses it to describe the rapid growth of online platforms. The other sentences use the word incorrectly — it cannot mean "present," "simplify," or "verify."

Question 4

In academic writing, the word "albeit" is used to:

Accepted Answer

introduce a concession or qualification

Answer

"Albeit" means "although" or "even though" and is used to introduce a qualification or concession. For example: "The results were promising, albeit inconclusive." It acknowledges a limiting factor without negating the main point.

Question 5

The passage states: "The delegation reached a consensus on the primary objectives, though several ancillary issues remained unresolved." The word "ancillary" most nearly means:

Accepted Answer

secondary

Answer

"Ancillary" means supplementary or secondary in importance. The contrast with "primary objectives" already resolved confirms that ancillary issues are lesser or supporting ones. It comes from the Latin for "helper."
