Which sentence correctly uses "affect" as a verb in an incident report describing an impact?
"The database outage affected checkout for roughly twenty minutes" is correct: "affect" as a verb means "to influence or have an impact on", which is exactly the meaning intended here. Option B confuses it with "effect" as a verb, which means "to bring about/implement", not "to influence". Option C wrongly uses "affect" as a noun in this context. Option D uses the noun "effects" where a verb is required.

Choose the sentence that correctly uses "effect" as a noun meaning "a result" in a root-cause analysis.
"...had an unexpected effect on p99 latency" is correct: "effect" as a noun means "a result or consequence", the meaning intended here. Option B incorrectly substitutes the verb form "affect" as a noun. Option C mixes both words incorrectly in a nonsensical combination. Option D uses "effect" as an unconjugated verb and "affect" incorrectly as a noun.
3 / 5
Which sentence correctly uses "effect" as the less common verb meaning "to bring about" or "to implement", as distinct from "affect"?
"...plans to effect several process changes..." is correct: the verb "effect" here means "to bring about/implement", a deliberate action, distinct from "affect" (to influence something already in progress). Option B uses "affect", which would mean merely influencing the changes, not implementing them — the wrong meaning for this context. Option C breaks subject-verb agreement and pluralizes "change" incorrectly. Option D awkwardly nominalizes "effect" where a bare verb is needed.
4 / 5
Select the sentence that correctly keeps "affect" and "effect" distinct when both concepts appear in the same sentence, in a postmortem summary.
"...affected response times, and the overall effect was..." is correct: "affected" (verb, influenced) describes the impact on response times, while "effect" (noun, result) names the overall consequence. Options B, C, and D all swap one or both words incorrectly, mismatching part of speech with intended meaning.
5 / 5
Which sentence correctly recognizes that "affect" as a rare noun (referring to observable emotion) does not belong in a technical incident report, choosing the standard alternative instead?
"The on-call engineer's calm response helped de-escalate the situation" is correct and clearest for a technical report: "affect" as a noun (a psychology term for outward emotional expression) is rarely appropriate outside clinical writing, so a plain word like "response" or "demeanor" reads more naturally. Option B uses the psychology-specific noun "affect", which is confusing and out of place here. Option C misuses "effect" as if it meant "demeanor". Option D pluralizes "affects" incorrectly.
