Actually willing to admit that they lack computer skills or other technical skills is not really used as a classical non-essential. So, we should read it as:

Willing to admit that they lack computer skills or other technical skills, many people are disinclined to recognize that their analytical skills are weak.

Also, this kind of structure is quite common. An example that comes to mind:

#25, OG13:

Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.

(A) Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.
{ "Like" must be used to compare nouns. For e.g:, Like Mary, Pam is pretty. The "beauty" of Mary and Pam is being compared. This answer option , which starts with "Unlike Computer schills or other technical skills", the first word after the comma should be a noun and should refer to something that needs to be compared with computer skills/technical skills. Hence this option is grammatically incorrect }

(B) Unlike computer skills or other technical skills, which they admit they lack, many people are disinclined to recognize that their analytical skills are weak.
{ Apart from the "like" error highlighted above, this sentence contains an additional error. The usage of "which" mandates that it should "kiss" a noun For eg : I like the shirt, which you wore to work yesterday. "which" should refer to the noun that is immediately to the left of it. This answer option implies that
"Which" refers to technical skills. The meaning of the sentence has changed}

(C) Unlike computer skills or other technical skills, analytical skills bring out a disinclination in many people to recognize that they are weak to a degree.
{ The "Like" error is rectified here. The construct, Unlike computer skills or other technical skills, analytical skills.....ensures that apples are being compared to apples. However, the meaning of the sentence has taken a turn for the worse. The usage "many people to recognize that they are weak to a degree" non-sensically implies that the many people realize that they are physically weak. In the original sentence, people realize that their analytical skills are weak }
(D) Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak. [simple and clear]
{ Short, Concise and Accurate. }
(E) Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills.
{ The usage "have a disinclination " is considered too wordy. Additionally, the meaning changes a bit.
The meaning changes to "Many people have a disinclination.....while willing to admit...... This implies that Many people have a disinclination while (ie at the same time) that they admit their lack of computer skills.
E.g : Pam was watching the movie while Joe was cooking dinner. This sentence implies that the actions are parallel - occurring at the same time. }

(A) Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak. (Illogical comparison)
(B) Unlike computer skills or other technical skills, which they admit they lack, many people are disinclined to recognize that their analytical skills are weak. (Illogical comparison)
(C) Unlike computer skills or other technical skills, analytical skills bring out a disinclination in many people to recognize that they are weak to a degree. [Comparison ok, but later part changes meaning]

(E) Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills. [wordy]

I would choose D.

A. Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.
WRONG: Disinclination is compared to Skills

B. Unlike computer skills or other technical skills, which they admit they lack, many people are disinclined to recognize that their analytical skills are weak.
WRONG: Changes meaning of the sentence a bit.

C. Unlike computer skills or other technical skills, analytical skills bring out a disinclination in many people to recognize that they are weak to a degree.
WRONG: Analytical skills cannot "bring out a disinclination"

D. Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak.
CORRECT: Meaning is conveyed and is correct in construction.

E. Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills.

Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak.

Ignore the underlined part and concentrate on the rest of the sentence. This is the one that makes most sense. The rest use improper comparisons.

In option D - isn't enclosed within comma making it non essential and thus changing the meaning drastically. E might be verbose but it is ensuring the logical meaning IMO. From D , I gather that the portion between the comma can be removed and this will change the meaning

Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.

The idea expressed here is that people don't recognize weakness in their analytical skills and that this is not the same with computer or technical skills. A and B don't make correct comparisons (between computer or technical skills and analytical skills) and are just awkward and wordy.
(C) Unlike computer skills or other technical skills, analytical skills bring out a disinclination in many people to recognize that they are weak to a degree still awkward and not direct enough
(D) Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak
(E) Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical wordy and shifts the emphasis away from the lack of recognition of analytical skill weakness

Answer D
_________________

The point of this sentence is to contrast how people feel about their computer skills or other technical skills with how they feel about their analytical skills. However, the awkward, wordy construction that begins with there is confuses this comparison, so that computer skills… are illogically contrasted with disinclination. Making the sentence more concise allows the contrast to be clear.

A An awkward, wordy construction prevents clarity of meaning; the comparison of computer skills… to disinclination is illogical
B Computer skills or other technical skills are illogically compared to many people
C The construction skills bring out a disinclination in many people is wordy, awkward, and idiomatically incorrect
D Correct. Making people the subject of the sentence allows a construction that clearly contrasts how they feel about the two sets of skills.
E Have a disinclination is wordy (the verb disinclined is preferred) and, when followed by while willing, creates an incomplete construction
_________________

I have a question concerning choice (E):

Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills.

The official explanation for why this choice (E) is wrong is as follows:

Have a disinclination is wordy (the verb disinclined is preferred) and, when followed by while willing, creates an incomplete construction

I agree that answer is wrong because it is wordy, but I don't agree that it creates an incomplete construction. I've been scouring through grammar forums and grammar articles. Everything that I've read leads me to believe that this construction is perfectly grammatical.

So, am I wrong or is the Official Explanation wrong?

Thanks for the detailed response.

While I have understood the rationale why B is wrong, something which I need help on is a sentence like below, will " which " like used in below sentence refers to technical skills only or it can be inferred correctly that it aims to address both computer and technical skills ?

(B) ...... computer skills or other technical skills, which ................

Thank You
Abhinav

Hey...
Yes this construction is incomplete because 'while' is a subordinating conjunction and needs a full clause associated...
Which could have been true if it said.."while people are willing to admit.."

Since 'people are' does not appear anywhere else in the sentence, it can not be ellipsed.
That's why it is incomplete.

Let me know if it helped.

Please help !!!
GMATNinja, aragonn, GMATNinjaTwo, hazelnut, generis

Not able to eliminate option E. I thought While is presenting a contrast here which is fine.
Other Folks has mentioned option E is wordy /awkward .. what it means ? also is while used here presents simultaneous action ?
DO we need have a IC after while ? its not present here

Please let me know how you will going to eliminate option E

soapbolt - It is better to us verb form "are disinclined", rather noun form "have a disinclination".
use of while clause is not right either. while clause is dependent clause, it need a comma before it. In general.


_________________

Two things are to be noted in E.
1. "Have disinclination" may not be incorrect grammatically, But it is definitively inferior as per the V-A-N rule of formal English.
2. The subordinate conjunction 'while', can only be used ahead of a subordinate clause with a subject and verb. The real proof is the current question on hand. We cannot take the official explanation as incorrect unless we have more information.
Is there any authentic example of 'while' that is accepted as a modifier as in E in any grammar book or dictionary? That will help to counter GMAC's OE.
