Are we not assuming that all the students in peer group are also 14 years old. I think without that assumption it is hard to arrive at the right answer choice.

I am not sure I understand your query.

School Administrator: The number of fourteen year olds in Britain who are considered “gifted” – that is who score higher than 90% of their peers on the mandatory secondary school entrance exam (MSEEE) – has increased steadily over the past decade.

We are talking about the fourteen year olds only. So the entire set is of only 14 year olds. There is no assumption here.

If the school administrator’s findings are correct, which of the following can be concluded on the basis of those findings?

(A) There has been at least some improvement in British education over the past decade. --Education? Can't say.

(B) The number of British fourteen year olds who are not considered gifted has decreased over the past decade. --This would result in a conclusion that is opposite of the current conclusion

(C) The number of British fourteen year olds taking the MSEEE has increased over the past decade. --Correct.

(D) Preparation for the MSEEE has improved in British schools over the past decade. --Preparation? Can't say

(E) The percentage of British fourteen year olds who are considered gifted has increased as a percentage of the total population. --As percentage of total population? Incorrect




if the no. of gifted student is 10 out of 100 ten years ago

can't it be 20 out of 100?... if yes, then how the no. of students who are taking MSEEE has increased?

Ma'am you understood correctly what I meant. How do we know that entire group is 14 years old. Prompt mentions Number of 14 years old and peer group. Can peer group not be, for example, a mix of 13,14 and 15 year old.

"Peer group" is the group of people who are equal in certain characteristics - here it is age. When you talk about the group of 14 year olds - those who got more than 90% of their peers and their peers, both are within the group of 14 year olds only.

My understanding is below.

"Peer group" is the group of people who are equal in certain characteristics - here all are taking MSEEE.

Please let me know the words that you referred in the prompt to ascertain peer group is of same age.

You are overthinking it.

We are talking about the set of 14 year olds. Out of that set, those who are considered "gifted" is a sub set. The peers of these "gifted 14 year olds" will be the rest of the 14 year olds. The comparison is among the fourteen year olds only.

If the school administrator’s findings are correct, which of the following can be concluded on the basis of those findings?

This is an inference question so best to stick with the information provided. Just to clear any misunderstandings - there is no information provided about total population size so will assume no change.
Next stimulus states
>90% (gifted) <90% (Not gifted)
10 yrs ago x y
Now a b

Assuming a+b = x+y
Given a>x Implies y>b

With word play only B and C is up for elimination - "can be concluded" rather than "must be true"

(B) The number of British fourteen year olds who are not considered gifted has decreased over the past decade. y>b
yes correct

(C) The number of British fourteen year olds taking the MSEEE has increased over the past decade. (not stated - outside assumption) -

Sticking to specifics is not working out in all cases?

Happy to learn about alternative explanations.

DebbieChats, You have remarkably removed the irrelevant options.
However, assuming there is NO information provided about total population size ---so will assume----> no change is an inference mistake.

Given:
    The # of gifted ones has increased steadily over the past decade.
    Meaning - if the prior count was 100x, now it is MORE THAN 100x

Let's clear out why B is wrong:
(B) The number of British fourteen-year-olds who are NOT considered gifted has decreased over the past decade.
    Before:
      Total = 1000
      Gifted = 600 | NotGifted = 400

    We will ONLY increase the gifted count in 2 different possible scenarios:
      After( 1st possible scenario) :
        Total = 900
        Gifted = 700 | NotGifted = 200 - NotGifted decreased

      After( 2nd possible scenario) :
        Total = 1200
        Gifted = 700 | NotGifted = 500 - NotGifted increased

    The count of NotGifted is NOT necessarily either higher or lower.
    It's Dicey --------> Thus, OUT!

(C) The number of British fourteen year olds taking the MSEEE has increased over the past decade.
    C needs to be TRUE because the gifted count is a subset of The number of British fourteen-year-olds taking the MSEEE count.
    Look at this way:
      In 2010,
        The number of aspirants taking the GMAT exam = 150
        The number of students who scored above 700 in GMAT = 150 - 150 students are part of 700-Club

      Now, in 2015,
        The number of aspirants taking the GMAT exam = Y1
        The number of students in 700 club = 200 - 200 students are part of 700-Club
        Y1 MUST be >= 150 (it should be >= 200, but we are comparing witht the initial count)
        because the The number of students in 700 club is a subset of The number of aspirants taking the GMAT exam.

as the exam is called "mandatory" should we make it a fact that if the number of 14 year olds increase the test takers will increase?
