Choose the sentence that correctly avoids an ungrammatical double negative:
"Doesn't have any coverage" is the grammatically correct standard English form: a single negative ("doesn't") paired with "any" (not "no") correctly expresses the absence of coverage. Options A and C both stack two negative markers ("doesn't/hasn't" + "no"), which in standard English grammar cancel out logically (implying the opposite — that there IS coverage) or are simply considered non-standard/ungrammatical, and should always be avoided in professional technical writing, where this kind of ambiguity can cause real confusion about test coverage. Option D compounds the double-negative error with an additional subject-verb agreement error ("don't" instead of "doesn't" with the singular subject "test suite").

Which sentence correctly uses an INTENTIONAL double-negative construction ("not uncommon") to make a hedged, diplomatic claim?
"Not uncommon" is a standard, grammatical litotes construction: "not" + a negative-prefixed adjective ("un-common") together produce a softened positive claim ("fairly common, but stated diplomatically"), which is a distinct and accepted pattern, unlike a raw double negative using two separate negation words. Option B stacks "not" with a second separate "not" rather than a negative-prefixed adjective, which is ungrammatical repetition, not the litotes pattern. Option C makes the same error with a contraction. Option D incorrectly uses "no" instead of "not" before the adjective, which does not form a grammatical sentence in this position.

A risk assessment states a cautious claim about feasibility. Choose the sentence with the correct grammatical litotes pattern:
"Not impossible" is the correct litotes pattern: "not" + a negative-prefixed adjective ("im-possible") to hedge a claim, meaning "technically possible, though difficult or undesirable" — softer and more cautious than simply saying "possible". Option B repeats "not" twice instead of using the negative-prefixed adjective form, which is an ungrammatical double negative rather than the accepted litotes pattern. Options C and D both incorrectly insert "no" alongside other negative markers, compounding into confusing, non-standard multiple negation that should never appear in professional risk documentation.

Which sentence contains an ungrammatical double negative that should be corrected before publishing in a style guide?
"Didn't introduce no new regressions" is the ungrammatical double negative: stacking "didn't" with "no" (instead of "any") produces non-standard grammar that should always be corrected to "didn't introduce any new regressions". The other three options are all grammatically correct: option A pairs a single negative ("couldn't") with "any", which is standard; option B ("not without complications") and option D ("not unreasonable") are both accepted litotes constructions using "not" + a negative-prefixed or negative-particle phrase to create a deliberate, diplomatic hedge, not an accidental double negative.

Choose the sentence that correctly uses "hardly" as a near-negative, avoiding a redundant double negative:
"Hardly ever expires" is correct: "hardly" already functions as a near-negative adverb by itself ("hardly ever" = "almost never") and should never be combined with another negation word like "doesn't" or "don't" in the same clause, since "hardly" is grammatically treated as negative for agreement purposes. Option A incorrectly pairs "doesn't" with "hardly", creating a redundant double negative. Option C stacks three negative-adjacent elements ("don't", "hardly", "never") and also has a subject-verb agreement error. Option D incorrectly combines "hardly" with "doesn't" in reversed order, which remains an ungrammatical double negation regardless of word order.
