Find the part of the sentence that contains an error: Had he not deferred the proposal for weeks, (1)/ the board would have had a better chance (2)/ to evaluating the project’s long-term viability (3)/ before the deadline lapsed. (4)
- (a)(1)
- (b)(2)
- (c)(3)
- (d)(4)
Answer
Why
Correct — C. Segment (3) reads to evaluating.
Here to is the infinitive marker that follows chance, so it needs the base verb: a better chance to evaluate.
Chance also takes of + -ing (a chance of winning), but to + -ing matches neither pattern. The fix lies wholly in segment (3) → option (c).
Why the others are wrong
- (a)(1) — Had he not deferred is an inverted third conditional, the formal version of 'If he had not deferred'. It needs no if and is correct.
- (b)(2) — Would have had is the regular result clause of a third conditional: would have + had, the past participle of have. The double have is correct.
- (d)(4) — Before the deadline lapsed uses the simple past for a completed past event, which fits the conditional's past time frame.
Concept
To does two jobs, and each takes a different verb form.
As the infinitive marker it takes the base verb: a chance to evaluate, able to evaluate. As a preposition it takes a noun or an -ing form: look forward to evaluating, committed to evaluating.
The test: if a noun could stand after to (look forward to the review), to is a preposition. 'A better chance to the review' fails, so here to is the infinitive marker.
Key facts
- chance to + base verb, for an opportunity: a better chance to evaluate.
- chance of + -ing, for a likelihood: a better chance of winning.
- Had he not deferred = If he had not deferred, an inverted third conditional.
- Preposition to takes -ing: look forward to meeting, committed to evaluating.

Common traps
- Suspecting segment (1) because it has no if. Had he not deferred is a correct inverted conditional.
- Suspecting segment (2) for its double have. Would have had is the standard third-conditional result.
- Treating every to as a preposition that takes -ing, as in look forward to.
The reverse case is 13 Sep 2025, 12:30, English Q.20: after the preposition in 'looking forward to', the keyed fix is 'to meeting you soon', an -ing form.
