Hi,

I chose C) but the answer is E). Could you explain why C) is wrong? :cry:

300. Following the destruction of the space shuttle Challenger, investigators concluded that many key people employed by the National Aeronautics and Space Administration and its contractors work an excessive amount of overtime that has the potential of causing errors in judgment.
(A) overtime that has the potential of causing
(B) overtime that has the potential to cause
(C) overtime that potentially can cause
(D) overtime, a practice that has the potential for causing
(E) overtime, a practice that can, potentially, cause

The answer should be E.
It should be the 'practice of overtime and not just overtime' that can potentially cause errors in judgement.
I have started to realize that I am the one!!!

Can anybody throw some light on the use of "has potential" and "potentially" ??

Sometimes it is best to rewrite the sentence when it is as long as this one.

Therefore consider the following:

Investigators concluded that many people work an excessive amount of overtime that has the potential of causing errors in judgment.

Without any analysis the revised sentence just sounds horrible.
Just like the original sentence, options (A), (B), and (C) present ambiguity; it is unclear what ‘that’ is referring to.

Furthermore, (D) must be eliminated because of verb tense. ‘Causing’ does not parallel ‘work’.
By process of elimination one is left with the answer (E).

Now try substituting the answer (E) with the underlined part of the new sentence up above.

"can" and "potentially" do not create redundance in E?, pls, explain

Thats a great question....I am waiting to see if anyone has an answer on this.

I dont have one, save that, the rest of the options are bad based on grammar wheras redundancy is a style-based rule and not necessarily a grammar based rule.
For love, not money.

Option - E is wrong

Refer to Q-159, OG-10
--------------------------------------

While depressed property values can hurt some large investors, they are potentially devastating for home-owners. whose equity--in many cases representing a life's savings--can plunge or even disappear.
(A) they are potentially devastating for homeowners, whose
(B) they can potentially devastate homeowners in that their
(C) for homeowners they are potentially devastating, because their
(D) for homeowners, it is potentially devastating in that their
(E) it can potentially devastate homeowners, whose
----
Explanation - "... can potentially is redundant in B and E. ..."

Its an OG-10 Solution.
