Sentence Correction

a However much parents in johnson's district may agree that the instructions of moral values should take place in the elementary school classroom, it is difficult for them to arrive at consensus concerning what those value are and how they should be taught.

Please can anyone explain that why the above sentence is correct instead of
Despite the fact that parents in johannson's district may agree that

because i think much is used with uncountable nouns but here parents are countable.

Hey,
'However much' is an idiom, meaning 'as much as'. So it does not involve any counting of parents here.

'Despite the fact that parents in johannson's district may agree that'- here fact and may do not go together, so it is incorrect.

Hope this helps.
