A soccer league is divided into a junior and a senior division, separated not by age but by a player’s skill level. This year, to determine the division for which an aspirant is best qualified, the league held a week-long trial, after which coach A and coach B selected players. Coach A nominated sixteen of the forty players for the senior league. Amongst Coach B’s nominations for the senior division were four players not nominated by Coach A. Therefore, there will be twenty players in the senior division.

Which of the following, if true, provides the strongest basis for the conclusion above to be warranted?

A) To be selected for the senior division, a player need only be nominated by one of the two coaches.
B) Of the sixteen players nominated by the coach A, coach B nominated more than half to play in the senior division.
C) All of the players not assigned to the senior division by both coaches were assigned to the junior division.
D) Of those chosen by both coaches to play in the senior division all will end up playing in the senior league.
E) The four players that Coach B but not Coach A selected for the senior division played the previous year in that division.

Hello sun01

Conclusion: Therefore, there will be twenty players in the senior division. [because]
Premise: Coach A nominated sixteen of the forty players for the senior league. Amongst Coach B’s nominations for the senior division were four players not nominated by Coach A.

Link:
In team will play twenty players because A choose 16 players and B shoose another 4 players.

A) To be selected for the senior division, a player need only be nominated by one of the two coaches.
Correct. This answer connected to the link and negation test destroy the conclusion.
If player need to be nominated by both coaches then team can not be from 20 players.

B) Of the sixteen players nominated by the coach A, coach B nominated more than half to play in the senior division.
Incorrect.We know nothing about how much players was chosen by both coaches.

C) All of the players not assigned to the senior division by both coaches were assigned to the junior division.
Incorrect.This information destroy the conclusion because we know that maximum possible number of players who was chosen by both coaches is 16

D) Of those chosen by both coaches to play in the senior division all will end up playing in the senior league.
Incorrect.We know nothing about sinor league.

E) The four players that Coach B but not Coach A selected for the senior division played the previous year in that division.
Incorrect. We know nothing about previous year.

Hello sun01.

I think the best book about CR is the Powerscore CR bible (with exception only about one it advice about not reading question before reading the argument).

If you want short version then you can read some articles on GMATClub site such as:
critical-reasoning-revision-assumption-193609.html
inference-vs-assumption-146758.html
critical-reasoning-shortcuts-and-tips-91280.html

In this post you can find a lot of links to other posts about CR
critical-reasoning-megathread-145178.html

Also you can try to watch "Thursdays with Ron" they have like 8-10 videos about assumption CR
Here is the list compilated by Engr2012
consolidated-thursday-with-ron-list-for-all-the-sections-201006.html#p1544515
You can select from excel file exactly what you need to watch.

Official Explanation


For the conclusion to hold true—there will be 20 players on the team—players need only be selected by one coach. If both coaches have to choose a player, then there is no way that conclusion can be validly drawn. At most, 16 players could be chosen, but that’s assuming coach B would choose every play that cach A chose. Answer: (A)

(A) See above.

(B) If (B) is true, the conclusion isn’t necessarily valid. Say, coach B nominated 9 of the sixteen players that coach A nominated. This information alone doesn’t automatically equate to 20 players.

(C) Based on information in the prompt, there could be zero overlap in the two coach’s selection. None of the 16 players coach A chose could be chosen by coach B. Therefore, (C) does not inevitably lead to the conclusion.

(D) Based on the information in the prompt, we do not have a definite number for the number of players chosen by both coaches. That number could range from zero to sixteen.

(E) Who played the previous year is irrelevant to who is playing in the senior division this year.
