Which sentence correctly uses negative adverbial inversion with Not only?
After Not only at the start of a clause, the auxiliary verb must come before the subject: Not only does this solution... The structure is Not only + auxiliary + subject + main verb.

A formal enterprise proposal uses conditional inversion. Which sentence is correct?
Conditional inversion (Should + subject + infinitive) replaces If + subject + should + infinitive in formal writing. The verb after the subject must be a bare infinitive (fail, not fails or will fail).

Under no circumstances should... is a formal inversion expressing absolute prohibition. It begins with the negative phrase, triggering auxiliary inversion. Common in security policies and formal technical guidelines.

During a code review of the authenticationService.authenticate() function, Sarah comments: 'Not only is this request missing a valid token, but the user's session has expired.' Which sentence best reflects the correct use of inversion here?
Inversion with 'not only' requires the main clause to come first and use the auxiliary verb (here, 'is') in its negated form. Option 1 correctly structures this pattern – 'Not only' is followed by the negative statement about the missing token and then a conjunction. Options 2, 3, and 4 incorrectly place words or use alternative phrasing that doesn't adhere to the inversion rule.

As a Senior DevOps Engineer, you're drafting a Slack message to inform the team about a critical outage affecting API endpoint /v1/users. You need to convey the urgency clearly and formally. Which sentence demonstrates correct inversion for emphasis?
When using 'rarely' with inversion, it's crucial to place the negative adverbial phrase first. Option 1 accurately uses this structure – 'Rarely' followed by the statement about the outage. Options 2 and 3 misplace 'rarely', while option 4 incorrectly adds an auxiliary verb where it isn't needed.

During a standup meeting, the Lead Architect, David, needs to highlight a critical issue with the new database schema. He says: 'Only by refactoring this module can we ensure data consistency.' Which sentence best demonstrates correct inversion using 'only by'?
The 'only by' inversion requires the negative clause to come first and use an auxiliary verb ('can') in its negated form. Option 1 correctly establishes this structure – 'Only by refactoring…', followed by the conditional statement about data consistency. The other options incorrectly change the word order or omit necessary elements.

You are writing a PR description for a code change that adds logging to a sensitive API endpoint. You want to explicitly forbid unauthorized access. Which sentence correctly utilizes inversion to express this prohibition?
Inversion with 'insufficient' follows a specific pattern – placing the negative adverbial phrase first and using an auxiliary verb ('we') in its negated form. Option 1 correctly implements this structure, emphasizing the restriction due to insufficient balance. The other options either misplace the words or fail to use the required auxiliary.

In a formal technical document detailing security protocols for a distributed system, you need to state that unauthorized modifications are strictly prohibited. Which sentence demonstrates correct inversion for this purpose?
When expressing a strong prohibition using inversion with 'not only', the negative clause must precede the statement of what's prohibited. Option 1 correctly structures this – 'Not only… are permitted'. This clearly establishes the restriction and reinforces its importance in formal documentation.
