Question

Quizplus · Accepted Answer

"Amount" is used when referring to things in bulk that cannot be easily counted (paperwork, homework, oil).
"Number" is used when referring to things that can be individually counted.
Since "effort" cannot be individually counted, the correct sentence should be:
Building this mosque took an incredible amount of effort, but we managed to finish it sooner than expected.
