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.

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.

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.

Hi everyone,

Context
A soccer league is divided into a junior and a senior division, separated not by age but by a player’s skill level.

Context
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.

Information used to draw the conclusion (note that here is the logical gap)
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.

Conclusion
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?

Pre-Thinking:
This is a strengthen question.

An assumption needed in order to draw the conclusion is that the players chosen by each coach for the senior team will enter the senior team without any further selection/approval from the other coach.

As a matter of fact let's assume that the 4 players chosen by CB are not approved of by CA and hence they don't become senior players. We can see how this would break down the argument and how the above assumption is needed.

Another assumption is the following: If, once a coach chose senior players, the players needed the approval of the other coach the other coach gave it to them.

Any new information along these lines will strengthen the argument

A) To be selected for the senior division, a player need only be nominated by one of the two coaches.
This works and it is in line with the assumption #1 drawn during pre-thinking. Hence correct

B) Of the sixteen players nominated by the coach A, coach B nominated more than half to play in the senior division.
Irrelevant

C) All of the players not assigned to the senior division by both coaches were assigned to the junior division.
Irrelevant

D) Of those chosen by both coaches to play in the senior division all will end up playing in the senior league.
Irrelevant

E) The four players that Coach B but not Coach A selected for the senior division played the previous year in that division.
Irrelevant

Here c should be the correct choice only. If all other players goes to junior division then automatically we have 20 players in senior div.

A is the most irrelevant.
