Which sentence correctly uses "too" to add a positive statement agreeing with a previous positive one?
"Passed too" is correct: "too" is used at the end of a positive clause to add agreement with a previous positive statement — both environments passed. "Either" (option B) is used to add agreement to a negative statement ("didn't pass... either"), not a positive one, so it is misused here. "Neither" (option C) introduces negative agreement and would incorrectly imply the production environment also failed. Option D combines a negative verb ("didn't pass") with "too", which is a mismatched pairing — negative statements require "either", not "too", at the end.

Which sentence correctly uses "either" to add agreement to a negative statement about two failing services?
"Didn't respond either" is correct: "either" is the standard word to add agreement at the end of a negative clause when confirming that a second negative situation also holds. Option A incorrectly pairs "too" with a negative clause, a mismatch since "too" is reserved for positive-clause agreement. Option C combines "didn't respond" with "neither" at the end, which is a double-negative-style error — "neither" is not used clause-finally after an already-negative verb in standard usage. Option D uses "either" after a positive verb ("responded"), which is also a mismatch since "either" requires a negative context.

Which sentence correctly uses "neither" as a standalone negative-agreement response, inverted with the auxiliary?
"Neither was the staging database" is correct: "neither" as a fronted negative-agreement word triggers subject-auxiliary inversion, matching the auxiliary of the original statement — since A used "wasn't" (a form of "be"), B correctly echoes with "was" inverted before the subject ("neither was the staging database"). Option B fails to invert, leaving normal word order after "neither", which is ungrammatical in this fixed pattern. Option C incorrectly switches to the auxiliary "did", which does not match the "be"-verb structure of the original statement ("wasn't migrated" uses "was", not "did"). Option D places "neither" mid-sentence without triggering inversion, which is not the standard pattern for this kind of short agreement response.
4 / 5
Which sentence correctly uses "nor" to continue a negative statement across two clauses?
"Nor does it sanitize output" is correct: "nor" continues a negative idea into a second clause and, like "neither", triggers subject-auxiliary inversion ("does it sanitize", not "it does sanitize"), a standard formal pattern for linking two negative clauses about the same subject or related subjects. Option B places the auxiliary after the subject without inverting, which breaks the required "nor + auxiliary + subject" order. Option C omits the auxiliary "does" entirely and fails to invert, using a plain present-tense verb instead. Option D redundantly combines "or" and "nor" together, which is not standard — "nor" alone carries the negative connective meaning.

A code review comment says: "This function doesn't handle null input, and the caller doesn't check for it _____." Choose the correct word to add negative agreement.
"Either" is correct: placed at the end of a negative clause ("doesn't check for it either"), it adds agreement with the preceding negative statement ("doesn't handle null input"), which is the standard clause-final negative-agreement word. "Too" (option A) is reserved for positive-clause agreement and cannot correctly close a negative clause here. "Also" (option B) is a positive additive adverb typically placed mid-clause, not used clause-finally to express negative agreement in this way. "Neither" (option D) would require restructuring the sentence with inversion (e.g., "neither does the caller check for it") and cannot simply be tacked onto the end of an already-negative clause like this.
