their last hope or their last hopes

I have a confusion about the usage of plural forms of uncountable & abstract nouns.

I come across both usages like:

  1. Their last hopes remain elusive

  2. Their last hope remains elusive

Is it okay to use plural forms of non-count & abstract noun?


Solution 1:

It depends on how many hopes there are. This is not the same as how many people there are.

For the people in the burning building their last hope is the fire brigade.

For the people sentenced to death their last hopes are presidential or governor's pardons.
