The government has been trying to introduce a new tax to discourage rampant misuse of agricultural subsidies; the challenge is whether the people will accept these after they are introduced.
A) will accept these after they are introduced
B) will accept the tax after it is introduced
C) accept it after they are introduced
D) accepted the tax after they were introduced
E) will accept these after being introduced
will accept these after they are introduced, here the pronoun these and they logically refer back to new tax, but in the original sentence the only plural antecedent is agricultural subsidies. This does not make sense as it is implying challenge is whether people will accept subsidies after subsidies are introduced.
[quote]B) will accept the tax after it is introduced[\quote]
this corrects the error by replacing plural these with the tax and they with it. singular it goes with singular tax.
