The expected rise in the price of oil could be a serious impact to industrialized nations and severely diminish the possibility to have an economy free of inflation.

(A) be a serious impact to industrialized nations and severely diminish the possibility to have
(B) seriously impact on industrialized nations and severely impede the possibility to have
(C) seriously impact on industrialized nations and severely impede the possibility of having
(D) have a serious impact on industrialized nations and severely impede the possibility to have
(E) have a serious impact on industrialized nations and severely diminish the possibility of having

I have two issues related to this question.

1) People say that "impact" cannot be used with "on" if it is a verb, but I looked up the dictionary and found an example that is contradicted to what people say. Ex) Her father's death impacted greatly on her childhood years.

2) Does the word "impede" change the meaning of the sentence?

Impede is different from diminish.
I think "diminish the possibility" is better suited here than " delay the possibility".

can you guys please elaborate on the discussion? I can't see why B is wrong, for me there are parellelism issues on the other alternatives.

Impede means to obstruct :
diminish means to reduce in value or effect.
You cannot obstruct the possibility of riots.
But,
You can obstruct the riots
on the other hand ::
you cannot diminish the riots
But,
You can diminish the possibility of riots.

So B ,D and C wrong
A wrong because ::
Noun (be a serious impact ) AND verb (severely diminish)
E correct by POE

IMO Correct answer should be ::
Seriously Impact industrialized nations and severely diminish the possibility of ...

Please correct me if i am wrong

Hi, there. I'm add my two cents to this discussion.

The expected rise in the price of oil could be a serious impact to industrialized nations and severely diminish the possibility to have an economy free of inflation.
(A) be a serious impact to industrialized nations and severely diminish the possibility to have
(B) seriously impact on industrialized nations and severely impede the possibility to have
(C) seriously impact on industrialized nations and severely impede the possibility of having
(D) have a serious impact on industrialized nations and severely impede the possibility to have
(E) have a serious impact on industrialized nations and severely diminish the possibility of having

As I read the prompt, two things grated on me --- "a serious impact to . . ." and "the possibility to . . . ." Those are both wrong.

To eybrj2, I would say: I don't know who says that "impact" should not go with "on", but those people are wrong. If the verb "to impact" is going to be followed by a preposition, the preposition "on" is the exact right one. That's the correct idiom.

Another correct idiom is the word "of" following "probability". We speak of a "probability of" something, not a "probability to" something.

Just with those two issues, here are the answer choices:
(A) be a serious impact to industrialized nations and severely diminish the possibility to have
(B) seriously impact on industrialized nations and severely impede the possibility to have
(C) seriously impact on industrialized nations and severely impede the possibility of having
(D) have a serious impact on industrialized nations and severely impede the possibility to have
(E) have a serious impact on industrialized nations and severely diminish the possibility of having

That leaves (C) and (E). Then we get to that funny word "impede."

First of all, "impede" means to hinder, to put up obstacles in front of. The word "diminish" means to make less.

Probability is an abstract mathematical thing --- ultimately, it's a number. One can make this number more or less, but something is quite bizarre about the idea of impeding a number. It's like being told that a football player tackled the number pi --- it just doesn't make sense.

Furthermore, to "diminish the probability of X" is idiomatic, whereas there's something inherent wrong/awkward/strange about "impede the probability of X."

That means (C) is out also, so (E) is the only choice remaining that is free of all mistakes and awkwardness. Answer = (E)

Does all this make sense?
Here's another SC question with some similar issues.

impact in B act as a verb which should be directly followed by an object rather than a preposition 'on'

Could impact X - impact as verb
could have impact on X - impact as noun

Hope you get the difference.

B/C are wrong for the above reason.
A/B/D - possibility/probability of is the right idiom.

IMO E.

Between options D and E.

When adjectives/verbs is used in combination with a preposition, it must be followed by a gerund, not by an infinitive.
With rule, option E is chosen.

WONDERFULL EXPLANTION.
there are 2 kinds of error on gmat sc, grammar error and meaning error. the first is grammar rules simple to remember. but, the second error is the key to success on sc. to find out meaning error, we use OUR COMMON SENSE OF OUR WORLD. this is the thing less discussed. of course, we have to have a good grammar before finding meaning logicness.

in our world , it make no sense to say: impede possibility. we impede a growth, a car, . this is the place gmat test us. very simple concept we need to know .

we should say, to lessen possibility. to diminish possibility.

Dear thangvietnam
My friend, I will simply add that I believe there are at least six kinds of errors on GMAT SC.
1) Grammar mistakes = B/W violations of clear grammar rules (SVA, verb tense, pronouns, etc.)
2) Logic mistakes = phrasing that are inherently illogical (e.g. "the student taller than everyone in her class.")
3) Changes in meaning = correct in and of itself, but different from the prompt meaning
4) Idiom mistake = wrong combination of words ("able for doing X")
5) Diction mistakes = using a word in the wrong way ("There were less accidents."
6) Rhetorical problems = a rhetorically strong sentence is clear, crisp, direct, and powerful, and it forcefully makes its statement. A rhetorically strong sentence is rambling, weak, unclear, tentative, mealy-mouthed, and unsure of itself.

GMAT SC is hard because you have to keep all these dimensions in mind at once.

Mike
