weaken the argument

by saurabhdhakad » Fri Aug 16, 2013 8:05 am
Hiring Manager: Here at Lightwave Industries, we have a rigorous process for analyzing job applicants so that we find the perfect match for a given position. While the process involves resume analysis, interviews, and a thorough vetting of all references, the interviews are most important: without them, we might occasionally hire people with personalities that are poorly suited to both the company and the specific position.

The hiring manager's conclusion about the importance of interviews depends on which of the following assumptions?

a.The only purpose of a job interview is to assess the personality of an applicant.
b.An applicant is not able to hide personality traits that may be detrimental to the given position or company.
c.All interviewers at Lightwave Industries are capable of determining whether a candidate's personality is a good fit for the company and position.
d.Most companies agree that a good personality fit is the most important factor in the job application process.
e.Lightwave Industries is not a business for which having a good personality match is a particularly important hiring trait.

In option C , this assumption also makes it sound by filling the gap that Interviewers are able to access the personalities in an interview. Isn't this option also holds true?
On negation : All would negate to none right?
Totally confused !

Conclusion : Without interview company might occasionally hire people with personalities that are poorly suited to both the company and the specific position.

C. (Negated) Few of the interviewers at Lightwave Industries are capable of determining whether a candidate's personality is a good fit for the company and position.

If the interviewers are not capable, even taking the interview serves no purpose because the wrong candidates may still be hired. It breaks the conclusion. Correct Answer is C.

Hi Mate,

Correct answer is B here.

Explanantion:

If you negate C it says that not all the interviewers are capable of determining whether a candidate's personality is a good fit for the company and position....so let us say not all the interviewers are not capable may be 2 are capable or may be 1 is capable...so the argument doesn't break down. So this is not the assumption. Hence option C is trap answer.

On the other hand if you negate B....It will say that An applicant is able to hide personality traits that may be detrimental to the given position or company......Now if an applicant is able to hide the personality traits then the interviewers won't be able to determine the true personality traits.

I hope this helps.

Thanks

Is negative of All is not all or None
All = 1-100
None = 0

None is the correct usage.

If None is right , then based on the suggested premises and assumption that with interview they are able to select the right candidate, right answer should be C ?
Whether the candidate would be able to hide or not , wont come in question if interviewers are not capable of judging the candidate.

No Mate,

Its absolutely wrong. If you negate the ALL then it is NOT ALL.....None is wrong negation absolutely wrong and I am 100% positive on this.
So answer B is the correct answer and C is the wrong answer. All means All everyone....but if you negate it means Not all may be not 1 or not 2.


I would recommend you to read the CR bible and build the basics because there are so many confusing Negation words.

None is wrong negation of All. Negation of All is not all.


Simple example:

All the people are drinking alcohol.
Now if you want to negate this you have to just show not all of them are drinking. You can show this by doing only 1 person is not drinking or 2 people are not drinking. It Doesn't have to be that None out of 20 people are drinking.

I don't if i am right here.
Actually I wrote few before but edited it as I was confused between few and a few.

But this is 100% correct -> few ~~ 0 or hardly any and a few -> some.

Hi everyone,

I've received a message asking me to provide some insight into this question. I'm going to offer a few hints/suggestions, then you can all think a bit more about this CR question.

1) STOP using the "negation test" - by focusing on the negation, you're missing the details in the prompt that matter.

2) Ask yourself this: WHY is the interview the MOST important part of the process? WHAT is it meant to keep from happening? Notice the SPECIFIC IDEAS THAT ARE WRITTEN.

3) Since you're all debating answers B vs. C, ask yourself which of these 2 actually meshes with the SPECIFIC IDEAS in the paragraph; DON'T change the meaning - use what's in the prompt. You'll find that the correct answer stands out.

Hi Rich,

The hint is helpful. Let me know if my explanation above is wrong. I am 100% positive about the explanation and the answer choice. I picked B and it makes complete sense if you negate. I think what some people have confusion about is negation of All. I am saying that negation of all is Not all but some people are saying its None. Which doesn't make sense to me.

Thanks
Rakesh

Can you please explain C is right. I have given an explanation above why B is right. Can you please provide the some insight what you think about B.

It is an OG12 question and the OA is B. I think you are confused about the negation of all vs none. IF not all the interviewers are capable of finding out about the person than does the argument fall apart....answer is NO....Let us say 1 person is capable of finding out may be not all but only 1 is....argument survives and hence option C is the wrong answer.

Thanks,
Rakesh

Hi All,

I'll be happy to explain why the correct answer is B, but first a quick point needs to be made:

There is NO SUCH THING AS 2 CORRECT ANSWERS on the GMAT. There is always 1 correct answer and 4 incorrect answers. The 4 incorrect answers might be incorrect for obvious or subtle reasons, but they ARE wrong.

For this prompt, I don't need to use the "negation test" at all; and to echo a point that I made before, it caused many of you to choose the wrong answer, so it's not a good approach.

In this CR question, we're told that interviews are the most important part of the hiring process at Lightwave Industries because without the interviews, WE MIGHT HIRE PEOPLE WITH PERSONALITIES THAT ARE POORLY SUITED TO BOTH THE COMPANY AND THE SPECIFIC POSITION. Focus on those words. They are the crux of the entire question. The company is trying to avoid hiring people who are POORLY SUITED for the company/position. The people who are hired DON'T need to be perfect, they could just be good, or even okay for the position, but the company is trying to avoid people who are POORLY SUITED.

Answer B discusses applicants who have personality traits that may be DETRIMENTAL to the position/company. This is EXACTLY who the interviewer is trying to weed out. One of the assumptions would have to be that a POORLY SUITED applicant couldn't hide those traits during an interview.

Answer C is tempting, but wrong. Here's why: It focuses on the interviewer's ability to determine if a candidate is a GOOD FIT for the company/position. Whether a candidate is a good fit is irrelevant; the prompt is talking about how to avoid people who are POORLY SUITED. A candidate who is NOT poorly suited isn't necessarily a good fit; he/she might just be a decent fit.

While this type of wrong answer can be subtle, it is also a common type of wrong answer on the GMAT (you'll see it in CR and in RC). The EMPOWERgmat course has a Module devoted to Wrong Answer Analysis and learning how to spot wrong answers (and avoid choosing them). This is something to keep in mind if you ever get stuck at a particular Verbal Score range.
