question - estimate labor

what do you think of this one and why

Your company has been hired to configure software in 500 computers. All computers need equal time to configure. You calculate the time to configure each computer as 5 hours. The cost for labor is calculated at $500 each computer. Your Project Sponsor disagrees with your labor estimate. Why is so?

1.You haven't completed one computer yet, so you don't know how long the work will actually take.
2.You have not factored in all of the effort applied to the work.
3.You have not considered the law of diminishing returns.
4.You have not considered the learning curve.

Good question!! what's the source?

I think the correct option is #4. The reason is the as more the team configures the computers, the efficient they become and thus take less time

Option 2 may not be correct because the cost given is only for labour. Other work like PM effort etc does not come in labor . hence the labor estimate is correct. 

Option 1 is not logical, since you are a company, you know the time required to configure the computer

Hence Option 4 is the only logically correct answer.
