Very few students take advantage of Shelbyville's school breakfast program, although it is available to all students. There is substantial research to show that students who do not eat breakfast learn less well than students who do. Therefore, in order to enhance the quality of learning that goes on in Shelbyville's schools, the school administrators should take steps to greatly increase the percentage of students who participate in the breakfast program.The conclusion of the argument is the following:
in order to enhance the quality of learning that goes on in Shelbyville's schools, the school administrators should take steps to greatly increase the percentage of students who participate in the breakfast program The support for the conclusion is the following:
Very few students take advantage of Shelbyville's school breakfast program, although it is available to all students.and
There is substantial research to show that students who do not eat breakfast learn less well than students who do. We see the the letter writer has reasoned basically that, since few students take advantage of the breakfast program and not eating breakfast causes students not to learn as well as they otherwise would, school administrators can improve the learning that goes on in the schools by getting more students to participate in the breakfast program, so they "should" do so.
Knowing which of the following would be most helpful in assessing the letter writer's argument?This is an Evaluate question, and the correct answer will be the one such that determining what it mentions will help with evaluating the case for the conclusion.
Specifically, in the case of this question, information on the percentage mentioned by the correct answer will weaken or strengthen the argument.
So, to find the correct answer, we can try extreme values for each answer choice and see whether those extreme values weaken or strengthen the argument.
A. The percentage of Shelbyville students who think that breakfast is the most important meal of the dayRegardless of whether 10 percent or 90 percent of Shelbyville students think that breakfast is the most important meal of the day, the argument is neither weakened nor strengthened by information on this percentage.
After all, what students think is not the point here. Regardless of what they think, getting more of them to participate in the program may serve to enhance the quality of the learning that goes on in the schools.
Eliminate.
B. The percentage of Shelbyville students who eat breakfast at home on school daysLet's see how extreme values for this percentage affect the argument.
We can first try saying that the percentage of students who eat breakfast at home is a low 10 percent.
In that case, we have confirmation that increasing the percentage of students who participate in the breakfast program would cause an improvement in the quality of learning. After all, in that case, currently just 10 percent of students eat breakfast at home and few eat breakfast at school.
So, in that case, by getting more students to participate in the program, administrators could greatly increase the percentage of students who eat breakfast on school days and thus enhance the quality of learning.
So, the information that 10 percent eat breakfast at home strengthens the case for the conclusion.
We can also try an extremely high value, saying the percentage who eat breakfast at home is 90 percent.
In that case, we have reason to believe that increasing the percentage of students who participate in the program won't make much difference. After all, in that case, it could be that all that would happen is that some students who were eating breakfast at home would start eating it at school.
Of course, in that case there's no reason to believe that increasing the number of students who participate in the program would enhance the quality of learning.
So, the information that this percentage is 90 percent weakens the case for the conclusion.
Thus, since different values for the percentage who eat breakfast at home strengthen or weaken the argument, determining this percentage helps with assessing the letter writer's argument.
Keep.
C. The percentage of Shelbyville students who are aware of the school breakfast programThis choice is a little tricky because, if a low percentage of students are aware of the program, that information means that making more students aware of the program could cause more to participate in the program and perhaps result in the desired outcome of enhanced quality of learning.
Notice, however, that the conclusion of the argument is not about how easy it will be to get more students to participate in the program.
Rather, the conclusion is about the EFFECT of getting more students to participate. The point of the argument is that getting more students to participate will CAUSE an improvement in learning.
So, to get this question correct, we need to note exactly what the conclusion is and eliminate this choice because information on whether students are aware of the program doesn't affect the case for the conclusion.
After all, regardless of whether 10 percent or 90 percent of the students are aware of the program, getting more to participate could cause an improvement in learning.
Takeaway: To get Critical Reasoning questions correct consistently, we have to carefully note conclusions of arguments and ensure that our answer is related to the conclusion we're dealing with and not to a different conclusion.
Eliminate.
D. The percentage of school-age children in Shelbyville who do not attend school regularlyInformation on this percentage has no effect on the strength of the argument since the argument is about "students" and "the quality of learning that goes on" IN SCHOOLS.
After all, regardless of whether 10 percent or 90 percent of school-age children in Shelbyville do not attend school regularly, getting more of the students who do attend school to participate in the program could serve to enhance the quality of learning that goes on in the schools.
Eliminate.
E. The percentage of students who participate in breakfast programs in towns other than ShelbyvilleInformation on this percentage has no effect on the strength of the argument.
After all, regardless of what percentage of students elsewhere participate in breakfast programs, getting more Shelbyville students to participate in the Shelbyville breakfast program could cause an improvement in the quality of learning that goes on in Shelbyville's schools.
Eliminate.
