Which sentence correctly uses "not until" in standard word order to describe a delayed discovery?
"The team did not notice the leak until the memory usage graph flattened out at the limit" correctly places "not" with the auxiliary "did" and uses "until" alone to introduce the delayed trigger point. Option B doubles the negator by adding an extra "not" before "until". Option C misorders "not" before "did". Option D misplaces "not" after the main verb instead of attaching it to the auxiliary.
2 / 20
Which sentence correctly uses fronted "not until" with subject-auxiliary inversion for emphasis in a postmortem?
"Not until the third retry did the request finally succeed" correctly fronts "not until" and inverts the subject and auxiliary ("did the request") as required after a negative adverbial at the start of a sentence. Option B keeps the subject before the auxiliary, failing to invert. Option C omits inversion entirely, which is required once "not until" opens the sentence. Option D scrambles the word order of the fronted phrase itself.
3 / 20
Which sentence correctly uses fronted "not until" with a perfect auxiliary to emphasize a very late fix?
"Not until version 4.2 had the root cause been properly addressed" correctly inverts the auxiliary "had" before the subject "the root cause" after the fronted negative adverbial. Option B keeps standard subject-auxiliary order, which is incorrect after fronting. Options C and D scramble the auxiliary, subject, and past participle into non-standard positions.
4 / 20
Which sentence correctly uses "not until" without inversion, in the standard main-clause position, describing a deployment gate?
"The release does not go out until every integration test has passed" is correct: with standard subject-first word order, "not" attaches to the auxiliary "does" and "until" alone introduces the condition; no inversion is needed because the sentence does not open with the negative adverbial. Option B misorders "not" and "does". Option C misplaces "not" before the subject. Option D incorrectly repeats "not" before "until".
5 / 20
Which sentence correctly uses fronted "not until" with a modal auxiliary to emphasize when a feature will become available?
"Not until the next quarter will the multi-region failover feature be generally available" correctly inverts the modal "will" before the subject after the fronted negative time phrase. Option B fails to invert, keeping the subject before "will". Option C moves "be" before the subject instead of "will", which is the wrong auxiliary to invert. Option D moves "will" to the wrong position entirely, before "the next quarter".

Sarah: 'We're not until the build passes all unit tests before deploying to staging. Seriously, that's the *only* trigger.'
Which option best explains Sarah's statement?
Sarah is using 'not until' to establish a hard requirement. This means the build *must* pass before anything happens, highlighting a deliberate and forceful delay based on a specific condition – not just a suggestion or potential event. The phrase emphasizes that deployment is contingent upon this outcome.
7 / 20
Mark (in a Slack message): 'Not until the performance metrics stabilize after the last change will I approve this release. We can't risk another spike.'
What is the primary function of 'not until' in Mark's message?
'Not until' here denotes a crucial condition: the performance metrics must be stable before Mark will authorize the release. This isn't simply delaying; it's tying approval directly to observable data and actively mitigating risk – a common practice in DevOps environments.
8 / 20
David (in a PR description): 'Not until the integration tests have successfully completed their run against the latest build will this code be merged.'
What does David's phrasing primarily convey?
David's sentence demonstrates a controlled and deliberate approach to code integration. The phrase 'not until' signals that the merge is entirely dependent on the successful completion of integration tests—a standard practice for ensuring quality and preventing regressions. It reflects a cautious strategy prioritizing thorough testing.
9 / 20
Emily (during a standup update): 'Not until the database migration is fully rolled out will we be able to start using the new user interface.'
What aspect of development does Emily's statement highlight?
'Not until' here illustrates a critical dependency. The new UI cannot function until the database migration is complete – showcasing how frontend and backend components often have intertwined deployment timelines. This highlights the need for coordinated releases and proper infrastructure setup before features can be used.
10 / 20
Ben: 'Not until the API endpoint is fully documented and tested will we proceed with building the client application.'
What does Ben's statement most accurately represent?
Ben's statement emphasizes the importance of foundational work – thorough API documentation and testing. This is a common practice to ensure compatibility and prevent integration issues later. The phrase 'not until' signifies that client development isn't initiated until these critical aspects are addressed, demonstrating a disciplined approach to software engineering.
