Which sentence correctly uses "respectively" to match two parallel lists in the same order in a performance summary?
"The staging and production clusters have 4 and 16 nodes, respectively" is correct: the first list (staging, production) is matched item-by-item with the second list (4, 16), in the same order, and "respectively" signals that pairing clearly. Option B adds a contradictory, confusing clarification. Option C misplaces "respectively" mid-sentence, breaking the pairing. Option D is grammatically malformed.
2 / 5
Choose the sentence that correctly places "respectively" at the end of the clause after both parallel lists have been fully stated.
"...own the React app and the Go API, respectively" is correct: "respectively" comes after both complete lists, at the end of the sentence, which is the standard and clearest position. Option B awkwardly inserts it mid-clause with a redundant "in order". Option C splits the second list, breaking the pairing. Option D places it at the very start, which is nonstandard and unclear.
3 / 5
Which sentence correctly avoids using "respectively" when the two lists don't actually have a clear one-to-one order, since misuse creates ambiguity?
"...were each affected differently by the outage" is correct: without a second parallel list to map against, "respectively" has nothing to pair with and should be dropped in favor of "each". Option B tacks on "respectively" with no corresponding list, making it meaningless. Options C and D repeat the same error with worse word order.
4 / 5
Select the sentence that correctly uses "respectively" with three parallel items on each side, keeping the same order in both lists in an incident report.
"The US, EU, and APAC regions recorded 2%, 5%, and 1% error rates, respectively" is correct: the three regions and three percentages are listed in matching order, and "respectively" at the end clearly signals the pairing. Option B adds a vague, contradictory qualifier. Option C and D explicitly contradict the meaning of "respectively" by suggesting the order doesn't matter.
5 / 5
Which sentence correctly rewrites a sentence to avoid a mismatched count between the two lists, where "respectively" cannot apply?
"The read replica handles queries, while the primary handles both writes and schema migrations" is correct: with two items on one side and three responsibilities on the other, there is no valid one-to-one pairing, so "respectively" cannot be used, and a clearer restructured sentence is needed instead. Options B, C, and D all force "respectively" onto a mismatched 2-to-3 list, which is ungrammatical and confusing.
