[Grammar] error-picking (otherwise; more than double)

[wahaha]

You must let them know that you need help, otherwise they are likely to
(A) (B) (C)
pass you by, not noticing that you are in need of help.
(D) (E)


Pick the error! The answer is B.

Why????:-(

I chose E, because I think without noticing is better.

Another question is:

She bought the house for fifty thousand dollars three years ago, but now
(A) (B)
it is worth more than double that amount.
(C) (D) (E)

The answer is D. I think these two answers are wrong!

 

[wahaha]

I wrote the answers!!

1. B--otherwise
2. D--more than double:shock:

hi,
Let me rephrase your question, I'm also interested in the answer.

There are two sentences the task was to pick the underline part that has an error.
Why the answers are otherwise and more than double respectively ?
What is the correct phrase to use instead of it ?
I think they could be "or else" and "over twice" .

You must let them know that you need help, otherwise they are likely to pass you by, not noticing that you are in need of help.


She bought the house for fifty thousand dollars three years ago, but now it is worth more than double that amount.

cheers

Can "otherwise" serve as a conjunction? It looks like a comma splice to me.

. Otherwise, not ,otherwise.

Do you think they expect "more than twice"? Because "more than double" sounds okay to me. Too colloquial?

The thing is I don't see anything wrong with the sentences but as the OP said they where the answers.
I thought how it could be rephrased and come up with the "or else" and "over twice" but still don't know why "otherwise" and "more than double" are considered as incorrect.
I think "otherwise" is used as an adverb + clause. I don't see any reason why it couldn't be placed after a comma.

I have to say that if someone had posted these sentences on here and asked us to spot problems/errors, I would have been inclined to say that they were both fine.

I agree with the OP that "without noticing" might be an improvement on "not noticing" but apparently whoever wrote the questions didn't!

With sentence 2, I wondered if perhaps it should simply finish "more than double that", but I don't think that removing "amount" was one of the possible answers.

Who writes these exercises?!

 

[wahaha]

Thanks all.

I read those questions on the exam for English teachers.

I 've searched on the website and considered both sentences are correct.

I agree with emsr2d2 and I do feel the examiner made mistakes!! :-(
