Confusable & commonly misused words MCQ — 15 Practice Questions with Answers

Explanation

Affect is normally a verb meaning to influence, while effect is normally a noun meaning result or consequence. In the first blank, the delay would influence or damage investor confidence, so affect is required. In the second blank, the phrase 'a measurable ___ on the company's credit rating' asks for a noun meaning impact; therefore effect is correct. The cue is the article 'a' before the second blank and the active verb position after 'would' in the first blank.

Explanation

Statement 1 states the standard distinction: a writer or speaker implies something, and a reader or listener infers it. The direction of meaning matters. Statement 2 is incorrect because it reverses another pair. Apprise means to inform or notify someone, as in 'apprise the board of the delay'. Appraise means to assess the value, quality, or performance of something or someone. Since only the first statement is accurate, option A is the defensible answer.

Explanation

Discreet means tactful, prudent, or careful in speech and conduct. Discrete means separate or individually distinct. In option C, the auditor's silence is tactful and guarded; it is not a separate unit or category. Therefore, discreet silence would be the correct phrase. The other options use the words properly: a discreet officer handles sensitive material carefully, while discrete categories and discrete variables are distinct units for classification or analysis.

Explanation

Effect is the noun required after the article 'a' and the adjective 'salutary': the phrase means a beneficial result. Affect is usually a verb meaning to influence, so 'had a salutary affect' wrongly uses a verb as a noun. Effect can also be a verb meaning 'bring about', as in 'effect change', but that sense does not fit the structure 'had a'. The cue is the noun slot after 'had a', which makes option A the only correct sentence.

Explanation

Both statements state standard distinctions. A historic decision is one of lasting importance; a historical novel, record, or site is connected with the past or with history. Similarly, economic policy, economic growth, and economic crisis relate to the economy or economics. Economical, however, means thrifty, efficient, or avoiding waste, as in an economical car or an economical use of time. The cue is that each pair has one term for a domain and another for significance or efficiency.
