A- it is the possibility
B- is the possibility
C- it is possible
D- then is possible
=> C. It seems "it" refers to REM so that " it is possible + to inf. verb"

2- The Irish brought the popular custom of Halloween to America .........1840s

A- into the
B- in the
C- within
D- during

=> C. in the 19......s

3- One of Hana Claus's experiments, a frothy ceramic called Beerstone, was produced.

A. It should be " one of the + Pl. Noun"

4- Robots are being used increasingly in industry as they can work on large jobs faster, are more precise and ...........

A- don't as easily tire
B- don't tire more easily
C- don't tire easily
D- don't too easily tire

=> It should be " B- don't tire more easily ' because of parallel structure more ....and... more

C- it is possible

Why A is not acceptable here, "It is the possibility to do sth" sounds OK to me. Is there any difference between A and C?

I agree with all your answers except the last one. If you choose B the "more" word will repeat itself and there is no need to emphasize on it. I think the correct answer is C

As my LM dictionary, the prepositions following the noun "possibility" are only "of" or "for", not "to"

I agree with studyusa, if you remove "more" here, you can't combine it in a parallel structure.

My point of view is(i missed the main verb;-)) that the correct one is C. I woudn't choose B because there is no sign in the sentence with whom the robots are compared. By and large , that "parallel construction rule" is a tricky one and one should think twice before applying it.

Ok, I've realised that there is already a comparison ("more presize"). So I'm looking forward to your ideas.

Let me try to explain!

4- Robots are being used increasingly in industry as they can work on large jobs faster, are more precise and ...........
A- don't as easily tire
B- don't tire more easily
C- don't tire easily
D- don't too easily tire

In this sentence, I seperate it in into 3 new ones:
1. Robots are being used increasingly in industry as they can work on large jobs faster
2. Robots are being used increasingly in industry as they are more precise
3. Robots are being used increasingly in industry as they ...???

Here, I realise that they are both comparison sentences, and they hide the comparative subject. I can rewrite 3 sentences:

1. Robots are being used increasingly in industry as they can work on large jobs faster than man
2. Robots are being used increasingly in industry as they are more precise than man
3. Robots are being used increasingly in industry as they ...???... than man
So, the original sentence is the combination of 3 above sentences with removing the hide comparative subject "man"
It also has the parallel structure, "as they can work on large jobs faster, are more precise and ...........", right???
if you set "C" here, structrure of the sentence will be lost the comparative meaning "more than". So at this time, the 3rd sentence becomes
3. Robots are being used increasingly in industry as they don't tire easily than man. ???
if We remove "than man" here, we can't put it together with the two remain sentences.
So B must be the Answer. At this time, the 3rd looks like:
3. Robots are being used increasingly in industry as they don't tire more easily than man. ??? Is it good?

Ok, i agree. Thanks.
