It is a wrong impression that "being" is always incorrect in GMAT. Yes "being" may add some extra baggage in the sentence and hence may push it to become wordy. But it does not imply that we should outright reject a choice that uses "being".
Check out question 101 in OG12
. Correct answer has the structure:Being heavily committed to a course of action...is likely to make an executive miss signs of trouble...
Here "being" is integral to the meaning of the sentence. It is the action of "being heavily committed..." that makes it likely for the executive to miss the signs...
Likewise, in the GMATprep question in discussion, choice D is not incorrect just because "being" is used. It is incorrect because it is unnecessarily wordy.
Wordy - Choice D - Being very reluctant to carry any extra weight on his plane when he attempted his solo transatlantic flight was the reason that Charles Lindbergh refused to carry even a pound of mail, despite being offered $1,000 to do so.
Precise - Choice E - Very reluctant to have any extra weight on his plane when he attempted his solo transatlantic flight, Charles Lindberghrefused to carry even a pound of mail, despite being offered $1,000 to do so
Lets see a simple example to illustrate the difference between D and E of the GMATPrep question:
Like D = Being very tired after a sleepless night was the reason Tim took the day off. - wordy and hence incorrect
Like E = Very tired after a sleepless night, Tim took the day off. - Precise and correct
As you can see E is precise and hence correct. But D is not grammatically incorrect. It is more wordy.
Now check out this sentence. It is like the correct choice in OG12
#101. Being fat was the reason Mary lacked confidence in her teenage years.
I actually cannot write an alternate version here just by deleting "being" and a few other words. The sentence with "being" is actually correct.
. Here as with correct choice in OG12
#101, "being" is required to communicate the meaning of the sentence.
So "being" is correct. It just depends on the context. Sometimes its essential to the meaning and sometimes it just adds more weight to the sentence and hence makes the sentence wordy.
Hope this helps.
