Which sentence correctly uses "not to mention" to add a further benefit after a positive claim about a migration?
"The new pipeline is faster and easier to maintain, not to mention significantly cheaper to run" correctly uses "not to mention" followed by a parallel noun phrase or adjective phrase adding a further point.

Option D adds an ungrammatical, redundant clause structure after the phrase.
2 / 5
Which sentence correctly uses "not to mention" (positive, additive) rather than "let alone" (negative-context minimizer) after an affirmative claim?
"The team shipped the feature ahead of schedule, not to mention with zero production incidents" is correct because the sentence adds a further positive point to an already-affirmative claim, which is exactly what "not to mention" does; "let alone" is reserved for stressing that something even more demanding is also untrue after a negative statement. Option B incorrectly uses "let alone" after a positive clause. Option C introduces a confusing double negative. Option D incorrectly merges the two fixed phrases together.
3 / 5
Which sentence correctly uses "not to mention" mid-sentence, set off by commas, listing an additional cost consideration?
"Running your own Kubernetes cluster requires dedicated ops staff, not to mention the ongoing infrastructure spend, which many startups underestimate" is correct, with the comma placed before "not to mention" and the bare infinitive "mention" intact. Option B misplaces the comma inside the fixed phrase. Option C splits "to" and "not" apart. Option D incorrectly uses the past participle "mentioned" instead of the base form "mention".

Which sentence correctly uses "not to mention" to add a further risk after describing a technical constraint?
"The legacy API has no rate limiting, not to mention no authentication on several endpoints" correctly repeats the parallel structure "no..." after "not to mention" to add a further specific gap. Option B swaps in "any", which breaks the parallel "no...no" structure used for emphasis. Option C adds a stray, ungrammatical verb at the end. Option D scrambles the fixed phrase's word order.
5 / 5
Which sentence correctly uses "not to mention" at the start of a follow-up sentence in a proposal, referring back to the previous point?
"Manual deployments are slow and error-prone. Not to mention the on-call burden they create every release" correctly opens the follow-up sentence with the fixed phrase "not to mention" directly before the noun phrase it introduces. Option B incorrectly uses a gerund. Option C splits "to" and "not" apart. Option D inserts an ungrammatical comma and verb "is" that breaks the fragment's intended structure.
