Select the most appropriate synonym of the given word. Fallacy

Correct — B. A fallacy is a mistaken belief, or a piece of reasoning that looks sound and is not. Its core sense is wrongness.

Error carries that sense directly: something that is incorrect.

The match is not exact — a fallacy is a false idea or a flawed argument, while an error can be any kind of slip — but a synonym item asks for the word that shares the core meaning, and here that is error.

Why the others are wrong

• (a)
  Veracity — Veracity means truthfulness or accuracy. It is the opposite of a fallacy, not a synonym for one.
• (c)
  Evidence — Evidence is the material that supports or disproves a claim. It belongs to the same discussion as a fallacy without meaning anything like it.
• (d)
  Verify — Verify is a verb meaning to check that something is true. Fallacy is a noun, so this fails on part of speech before meaning is even weighed.

Synonym items are settled on the core sense of the word, not on subject area. Veracity, evidence and verify all belong to the vocabulary of truth and proof, which is why this set feels harder than it is.

Fallacy reaches English from Latin fallere, to deceive, through the idea of a deceptive appearance. Modern use splits two ways: a false belief that people hold, and a defect in an argument.

Both readings land on the same idea — something is wrong — and that is what a synonym has to match.

Key facts

• Fallacy: a mistaken belief, or an argument that is unsound while appearing valid.
• Veracity: conformity to truth — the antonym of fallacy, not its synonym.
• Verify is a verb, while fallacy, veracity, error and evidence are all nouns.
• Fallacy derives from Latin fallere, meaning to deceive.

Common traps

• Picking veracity because it looks like the most academic word on the list.
• Overlooking that verify is a verb while the question word is a noun.
• Treating evidence as a synonym because both words turn up in arguments about proof.
