A noun as an adverb

[MikeNewYork]

Dear teachers,

"This will be followed by a multimillion-dollar restoration of the hall,

expected to last three to five years. "

Could you explain the function of 'three to five years' in the sentence?

Is 'three to five years' an object of 'last'?

I don't think so! The sentence speaks for my opinion about a noun as an

adverb.

Could you tell me your thought?


All the best,

This is very simlar to the original question. It can be, as TDOL said, an ellipted adverbial prepositional phrase, but a simpler answer is the same as before. This fits the usage of "last" as a transitive verb. In this case, the phrase is the object of "last".

last
v.tr.
To keep adequately supplied: left enough bread to last the family for the weekend.
To persist or endure for the entire length of; survive: hoped to last the season without injuring her leg again.
