Namaste Studio, founded in 1974, is widely regarded as one of the most

Option A says the students of Thursday are more advanced than those of Tuesday, but they may all be new or old students. Cannot draw a conclusion with option A.
I answered as Option E but I'm convinced with OA D

A) States that instructor's 2 type of classes are not same.
This can imply that her performance is not same in 2 type of classes. Therefore, her performance is inconsistent.

Whereas, D) states that people who taken the survey are not same.
This can imply that both groups had different perspectives to rate the performance of the instructor, although her performance was same.

Hope this helps.

premise: Although Angela has been teaching yoga at Namaste Studio for three years

Most students in the Thursday class have studied yoga at the center for five years, while most students in the Tuesday class are taking their first yoga class.

option D : Most students in the Thursday class have studied yoga at the center for five years, while most students in the Tuesday class are taking their first yoga class.

another reason to weaken conclusion : her performance as an instructor is inconsistent ; is that students on thursday class are more experienced in comparison to tuesday batch of students..

Hi Wonderwoman31
Please note that we have to weaken the argument

And the conclusion is she is best in afternoon Tuesday class and she is 4th in morning Thursday class

therefore,

A:The students in Angela's Thursday class are more advanced than those in her Tuesday class.
if this is true, than it means students result are TRUE representative of the efficiency of the TEACHER.

because , if thursday student are advanced, they would know more about yoga and hence would be able to potray the correct result about the efficiency of the teacher
and since, Tuesday result are less advance, they would know less about yoga and hence would not be able to potray the real image of the efficiency of teacher

I think both A and D implies that her performance might be consistent but they are perceived differently by two set of audience,

I am not able to connect the cues you have supplied. Instead, my understanding is that in both options A and D students might perceiving differently though she might be performing the same. Could you please shed more light on how is A different from D

Hi Wonderwoman31

passage states: Although Angela has been teaching yoga at Namaste Studio for three years.
prethink: therefore, We have to find an answer choices that resonates with the experience of student but in terms of YEARS of EXperience with the Namaste institute.

D:Most students in the Thursday class have studied yoga at the center for five years, while most students in the Tuesday class are taking their first yoga class.
Means students are WELL VERSED and AWARE about the performance of the TRUE PERFORMANCE consist of, Hence Thursday student correctly represent the performance, BUT tuesday Students are not AWARE of the PERFORMANCE criteria, thereby RANKED THE instructor AS 1st inspite of the performance....Actual performance of the instructor is 4th, as correctly stated by the Thurdays students


A) The students in Angela's Thursday class are more advanced than those in her Tuesday class
please note that Being advanced does not itself translate to being good Judge/ they coudl be good judge/they could not be good judge ....answer remains DOubtfull.....whether the student result is TRUE or NOT TRUE representation of result.

Wonderwoman31,

This question is horrifying. My thoughts and feelings towards it are so heinous, that they are illegal in 200 countries and decorum prohibits me from commenting them here. First off, (D) doesn't weaken the argument. It really doesn't. It could weaken it, but it might strengthen the argument. Second, the 'inconsistency' they speak of could be a on class basis, on a daily basis, weekly basis, monthly basis, or yearly basis. This question requires so many assumptions on so many levels that this question should be ignored. Please stick to high-quality questions!

If we are weakening the assumption that she is an inconsistent yoga instructor. Then we are finding reasons either making her consistent or opening the possibility she cannot be definitively considered inconsistent simply on the basis of the presented evidence; not a question of if she is good or bad, her worst ranking is still 4th out of 50 teachers after all; more about consistency and specifically in explaining ostensively inconsistent student feedback between two classes.

In which case, it holds that Option D is the only option which really does this: weakens any claims of inconsistencies in her teaching. It implicitly negates the ranking she receives on Tuesdays where she is often and mostly teaching students in their first yoga class, so naturally, as is the case she will receive the ranking of being the best yoga teacher as these students logically have not had any other yoga teacher before! So, essentially her Tuesday rank can now be totally discounted/tainted from being considered. Which means there is now only one set of objective rankings that can be considered which is the Thursday ranking and so clearly now also no possible inconsistency or paradox in her teaching quality/rank.

It is probably more simple than a 75% level question should be, but a little tricky still I guess.

Also in response to other comments on the validity/quality of the question.

The fact that an answer states that on Tuesdays it is many of the student's first class is the key information here. It means the vote of her being the best teacher given on Tuesdays simply cannot hold any real weight, so on that basis, I think the question is not a bad / it is a fair question; Answer D, does just as it must do: it introduces a subtle detail which totally negates the paradox and the basis of any claim of inconsistency thus weakening the stem argument.

Why not C???
If class is big, teaching each of them will be an uphill task, and thus not everyone is satisfied from the way she instruct.
