It took great effort for the men to move the bed

Explanation:

• There is a difference between the word "great" and "large" when it comes to using them in different sentences.

• Large is usually used to signify the size of a thing in amount e.g. His bag was pretty large.

• On the other hand, Great is used to express non-physical things e.g. feelings, emotions or actions.
