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.
3 / 16
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 / 16
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.

Liam (in a Slack channel) writes: 'The new deployment failed, and the monitoring system isn't showing any updates _____.' Which word best completes this sentence to express negative agreement?
'Neither' used in this way creates a parallel negative statement. The correct answer reflects the structure of 'neither… nor,' which is standard for expressing simultaneous negatives. The other options present unrelated or contradictory ideas that don't fit with the intended grammatical construction.
7 / 16
PR Description: 'We've implemented the new caching layer. The old version isn't working correctly, and the legacy code doesn't handle concurrent requests _____.' Select the best word to complete this sentence.
'Neither' in this context indicates a parallel negative consequence. The sentence highlights two negative aspects of the previous system – malfunctioning and inefficient use of resources. The correct answer maintains the structure of 'neither…nor,' reinforcing these combined negatives.
8 / 16
API Response: 'The payment gateway is unavailable, and the shipping service isn't processing orders _____.' Which word best completes this sentence to reinforce the negative agreement?
'Neither' is used here to express that both the payment gateway and shipping service are experiencing problems. The response describes two negative situations; 'neither' correctly links these together to reinforce the shared issue. The other options offer potential solutions or unrelated details which don't fit the grammatical structure of expressing simultaneous negatives.

During a code review, Sarah commented: 'The database connection isn't established correctly, and the error logging isn't configured properly _____.' Which word best completes this sentence to express negative agreement?
This question tests understanding of 'neither' when used to negate two related statements. The core concept is that 'neither' joins two negative clauses, signaling a complete absence of something. Using 'too' or 'either' would introduce positive agreement, which isn't the intended meaning here. 'Nor' doesn't fit the context of joining two negatives.

PR Description: 'We've refactored the user interface. The old JavaScript library isn't optimized, and the CSS stylesheets aren't responsive _____.' Select the best word to complete this sentence.
This scenario assesses the use of 'neither' to connect two negative aspects of a software improvement. The question uses terminology common in web development – UI, JavaScript, CSS. 'Neither' correctly joins the two negatives by indicating that *both* elements are deficient or not meeting requirements. This reinforces the idea of complete absence.

During a standup update, David said: 'The build process isn't running correctly, and the deployment scripts aren't deploying to staging _____.' Choose the correct word to add negative agreement.
This exercise tests 'either' in a context related to technical processes. 'Either' is appropriate here because it's used to indicate that *at least one* of the two processes is failing. It suggests there's a problem with either the build or deployment – a common situation in DevOps. 'Neither' would imply both are entirely absent, which isn't necessarily the case.

Reviewer: 'The API endpoint is returning a 500 error, and the documentation doesn't specify the expected data format. _____.' Choose the best word to complete this sentence.
Neither is used to express negative agreement when referring back to two previously stated negatives. Using too or either would introduce a positive element where we need to reinforce the existing negative statements about the API and documentation. nor requires a preceding 'and'.
16 / 16
PR Description: 'We've updated the authentication module. The old session management isn't secure, and the password reset flow doesn't require multi-factor authentication _____.' Select the best word to complete this sentence.
Nor is used to continue a negative statement across two clauses. Using too or either would introduce a positive element where we need to reinforce the existing negative statements about session management and password reset flow security. so indicates cause and effect.
