3 / 5
Which sentence correctly distinguishes "were it not for" (formal, inverted) from the equivalent informal "if it weren't for", without mixing the two structures?
"Were it not for the automated test suite, this regression would have shipped unnoticed" correctly uses the fully inverted, formal structure without "if". Option B wrongly combines "if it weren't" with an extra "not". Option C wrongly mixes both forms together. Option D wrongly uses "was" instead of the subjunctive "were".

Which sentence correctly follows "had it not been for" with a noun phrase rather than a full clause?
"Had it not been for a last-minute patch, the vulnerability would have remained exploitable for weeks" correctly follows the phrase with a simple noun phrase, "a last-minute patch". Options B, C, and D all incorrectly try to attach a finite clause after the fixed phrase.
