Question

She was shocked (a)/ to hear that (b)/ his mother died (c)/ from an accident (d).
A) She was shocked
B) to hear that
C) his mother died
D) from an accident
E) No error

Answer 1

I think that the answer is - E) No error

Answer 2

C is a clear error

It should be h(er mother died)

But if possible that two error are here

Then I will also go for D

beacause accident is used with preposition in and not from (maybe it is possible,I'm not sure about that)

Otherwise your answer is C
