Sentence Correction: Preposition Questions - Split Constructions

The board of directors of Aqua Pharmaceuticals has requested the representatives of the new ecological brand to elaborate and further discuss the proposal to add the brand to the company's products so the members of the board have all the necessary information.

Good job!

[[snippet]]

This answer choice corrects the original mistake by adding the required preposition on after the verb elaborate.

This answer choice is grammatically incorrect.

[[snippet]]

This answer repeats the original mistake.

Furthermore, this answer choice does not fit into the original sentence as a result of the omission of its final word (to).

This answer repeats the original mistake.

Another grammatical mistake in this answer choice is a Subject Verb Agreement mistake. The singular subject board does not agree with the pluralverb have.

The following Stop Sign help us identify this mistake:

- an X of Y subject

Did you notice the subject was in X of Y format? (i.e., board of directors)

That's right. Next time, when you spot this Stop Sign, be sure to examine Subject Verb Agreement extra carefully.

Remembering Stop Signs and identifying them in Sentence Correction questions are important. Stop Signs help you identify mistakes in the original sentence. Make sure that from now, you'll remember the following Stop Sign:

An X of Y Subject

This answer repeats the original mistake.

Furthermore, the addition of the word briefly creates an illogical sentence as to elaborate on something means to discuss it with detail, which is opposite to discussing something briefly.

This exam is also about the details and they love tripping test takers up with such changes.

Be extra vigilant!

Yup. I know this stop sign.

No. I forgot about this Stop Sign.

Actually, I didn't notice has was changed into have.
