A certain baseball team has just completed its season. In stadiums that seat 20,000 or fewer people, the team
averaged 1 home run per game; in stadiums that seat between 20,000 and 40,000 people, the team averaged 2
home runs per game; and, in stadiums that seat 40,000 or more people, the team averaged 3 home runs per
game. Obviously, the excitement of playing in front of large crowds motivated the team to hit more home runs.
Assuming that all stadiums during the season were filled to capacity, which of the following, if true, most undermines
the argument above?


A0 The team’s leading home run hitter hit more home runs in mid-sized stadiums than in large stadiums.
B) The fans in the larger stadiums often cheered against the team.
C) The team averaged only 2 home runs per game when playing in the league’s largest stadium.
D) In order to create seating for the additional fans, the outfield walls in the larger stadiums were constructed closer
to home base.
E) The team’s announcer cited crowd noise as a major motivator for the team.

D) is right.

In order to create seating for the additional fans, the outfield walls in the larger stadiums were constructed closer
to home base.
>>> This means that in the stadium which could seat 40K people, 40K seats were actually not filled. The walls were brought closer to the base.

Hence, score is not proportional to the number of people in audience.

Pre phrasing the answer helped me out in this question.

Premises suggest clearly that the team was hitting more home runs whenever it played in stadiums that had "Larger capacity to seat the audience"

Conclusion States that - "the excitement of playing in front of large crowds motivated the team to hit more home runs"

In order to weaken this reasoning - I thought of following options before checking the AC's

1) team was playing a weaker team in all those games where they hit Home runs

2) either the grounds were smaller where the team was playing

and then after Reading the AC's i could pick {D} easily.

{D} provides the reasoning that since home base was made smaller to seat more audience, Team was able to Hit more Home-runs in stadiums which were largely crowded.
Thus refuting the conclusion that the baseball team was playing better just because there were large crowds.

(A) The argument makes a claim about the collective behavior of the team. This collective claim does not preclude certain individuals from hitting fewer home runs in larger stadiums.
(B) The claim made in the argument is based on the size of the crowd in each stadium. For whom the fans cheered is irrelevant to the argument.
(C) Similar to answer choice A, this choice cites one specific example of contradictory information, while the argument is based on the average behavior
of the team throughout the entire season. The does not strongly undermine that, on average, the team was motivated by larger crowds.
(D) CORRECT. This choice explains that the larger stadiums actually have different dimensions from the smaller stadiums. In order to accommodate a larger number of fans, the outfield walls are closer to the batters. Thus, it is very possible that the greater number of home runs is due to the fact that the ball does not have to travel as far in larger stadiums.
(E) The announcer’s opinion is not relevant to the argument, and, even if it were, this choice would strengthen the argument.

Some great responses to this question already, so I just wanted to chime in with a little general context. The assumption made here eliminates alternatives. Be on the lookout for this category of assumption any time the Conclusion provides an explanation for some phenomenon:

Premise: The team hits more homeruns in stadiums with larger capacity. (This is a phenomenon that has been observed.)
Conclusion: The excitement of a larger crowd causes the team to hit more homeruns. (This is an explanation of the phenomenon.)

The first question you should ask when you see this structure is "are there any other explanations?"

The correct answer to a Find the Assumption or Strengthen the Conclusion question should eliminate the alternatives. The correct answer to an Evaluate the Argument question should ask if there are alternatives. And the correct answer to a Weaken the Conclusion question should provide at least one such alternative – (D) does the trick in this problem.

Try to place assumptions into categories such as this one. It makes brainstorming much easier!

Cheers,
Mark

Can someone explain How is C incorrect?
According to conclusion team performs better with more crowd, but when playing on largest stadium rather than hitting maximum home runs, team performed below average.
thus undermines the conclusion.
Please correct my reasoning.

Aditya,

I do understand where your confusion comes from. You can think of it as this way: (notice the bolded letters)

Category 1: stadiums with seats <20,000 --> 1 home run/game
Category 2: 20,000 < stadiums with seats <40,000 --> 2 home runs/game
Category 3: stadiums with seats > 20,000 --> 3 home runs/game

Answer Choice C: The team averaged only 2 home runs per game when playing in the league’s largest stadium.

It may be the case that although the team averaged only 2 home runs in its LARGEST stadium, the other stadiums in Category 3 averaged 3 home runs/game. Therefore, the largest stadium would be just an anomaly and doesn't necessarily weaken the argument.

Conclusion: excitement of playing --> motivated the team to hit more home runs
Weaken the arguments: Excitement of playing in front of large crowd might not be the reason that motivated the team to hit more home runs
D. Provide possible reason : the outfield walls in the larger stadiums were constructed closer
to home base --> hit more home runs
