Hi, teachers...

This time "agreement"

8 tons of water is needed.
8 tons of water are needed.

Which is correct?

Best regards...

"Is needed" sounds better.

'Is' sounds better because it is a single quantity of water which is needed for this recipe (and it must require a very big stewpot!). However, both are grammatically correct and semantically possible.
