Apostrophes

[beastmaster]

years --'s' here is plural S not possessive s so the first sentence is true

[çakırpençe]

As ı could remember ı ve come across a sentence like the one which is apostrophed.
thennn
you native speakers! tell us the exact onee pleaseee

[laureljohnescu]

To Panjandrum:

Apostrophes are used for two purposes: to show possession and in contractions.

POSESSION
In the case of the expression "a winter's day" the day belongs to winter. However, in this case, the years don't belong to the jail. Do you understand?

CONTRACTIONS
I cannot swim. OR I can't swim.
They both mean the exact same thing, it's just an abbreviation.
But this case doesn't use contractions.

I would write: The crime can be punished by up to ten years in jail.

None of the other choices (with or without apostrophes) sound correct to my AE ear.

[Thieugia]

According to Advanced Grammar in Use by Martin Hewings, Unit 53, both of ten years' jail and ten-year jail are correct..

[bianca]

There's a slight difference in meaning between ten years' jail and ten-year jail, though.

Ex.:

Ten years' jail is a real waste of human life. (or: ten years in jail is...)
He received a ten-year jail sentence.

A simple way of explaining this is to talk about "one year's jail". If it's one year in jail, why is there an "s" on the end of year? It's not there to signify that it's plural, so it must be there to signify possession. In which case it does have an apostrophe. So, "five years' jail" is correct.

I follow daizee. The second one is right. Look at his explanation.

The crime can be punished by up to ten years' jail.

[atlaisha]

What about this one? Does it sound correct?:

The crime can be punished by up to ten years of jail.
Thanks
