Can anyone help me on these questions please?

Hello everyone, I am going to take an English exam very soon, thus I have done some english mock papers. However, there are some questions which I got incorrect answers. So I would like to ask if anybody can explain to me please? (If the above sentences are incorrect too, please correct'em)

Here is one of the question (Error Identification):

Equipment (A) breakdowns in industry accounts (B) for annual losses (C) of billions (D).

A. Equipment

B. account

C. losses

D. billions

E. No error

What do you think the answer will be?

To avoid too much in one post, other questions will be seperately posted.

Thanks for everyone!
