In an Experiment, Two Different Types of Recorded Music were Played

QUESTION: In an experiment, two different types of recorded music were played for neonates in adjacent nurseries in a hospital. In nursery A, classical music was played: in nursery B, rock music was played. After two weeks, it was found that the babies in nursery A cried less, suffered fewer minor ailments, and gained more weight than did the babies in nursery B.

In evaluating the validity of the conclusion suggested by the experiment above it would be most important to know which of the following?

A) The musical preferences of the parents of the two groups of newborns.
B) Whether the newborns in both the nurseries were equally healthy and happy at the start of the experiment.
C) Whether loud rock music can damage the hearing of newborns.
D) what the average weight of the neonates was before and after the experiment
E) Whether the music was played in the nurseries at all times or only at certain times.

In an experiment, two different types of recorded music were played - is a GMAT Critical question. This particular GMAT Critical Reasoning topic has been taken from the book ‘GMAT Graduate Management Admission Test Exam Practice Questions & Dumps’. In this question, the candidates need to evaluate the validity of the conclusion. Then they need to select the correct answer from the provided options. GMAT critical reasoning tests the logical and analytical skills of the candidates. Critical reasoning in GMAT requires candidates to find the strengths and weaknesses of the argument, or find the logical flaw in the argument. The GMAT CR section contains 10 -13 GMAT critical reasoning questions out of 36 GMAT verbal questions.

Answer: B
Explanation: The GMAT Critical Reasoning tests a competitor's cognitive, logical, and scientific reasoning skills. The applicant must justify the correct choice by following the same correct statement or removing irrelevant arguments.

To resolve this issue of the Ascension, we must separate the dispute. The next sentence contains a proposition (must), so this is a decision and the main necessity is a reason.

Now let us check the option one by one:

1. The musical preferences of the parents of the two groups of newborns.
   Incorrect
   There is no difference here. Children's preferences in music and food are not unusual. Parents' preferences don't matter because everyone has the freedom to choose a snack and it doesn't mean they change their lifestyle or habits, so it doesn't affect the children's preferences.
2. Whether the newborns in both the nurseries were equally healthy and happy at the start of the experiment.
   Correct
   This is the correct choice because we need to be sure that they are both the same before we can begin to determine that music is the element that produces something. Newborns are just as healthy, no doubt about it. They were both happy. Because nursery A can be a nursery reserved for solid babies and nursery B can be allocated to premature babies who need incubators. Both nurseries were reasonably identical at the start of the experiment. There are slight differences in the types of music played in these two kindergartens, but they are similar in the beginning to come to the decision that music is the element that causes something to happen (in this case, in this type of music).
3. Whether loud rock music can damage the hearing of newborns.
   Incorrect
   This option is incorrect because it describes a situation without explaining how it affects children's health and well-being. They explain how music affects their health and well-being, including physical and psychological problems, hearing loss and weight gain. The option does not explain the patient's conditions (crying, pain, weight, etc.). Hearing loss doesn't agree with weight gain and doesn't care about traditional music and nursery schools either. Noisy just adds new data. We are not told about the volume of the music.
4. What the average weight of the neonates was before and after the experiment.
   Incorrect
   This option doesn't really explain the problem. Because there's no telling how long these babies will cry and in what week they'll gain every pound. It is also unclear whether her weight gain is 1 pound or 2 pounds per week. Further study on this topic will help arrive at a better solution.
   We've been looking closely at average weight gain and it's not actually directly related to how sick your child is (average weight gain). In fact, it seems more likely that they are on different farms.
5. Whether the music was played in the nurseries at all times or only at certain times.
   Incorrect
   This possibility does not explain the problem because children may have tendencies in the past. Students should be aware that many problems can be found with the proposed method of teaching individuals. The argument does not provide evidence that the principal's choice was wrong, nor does it explain why providing accommodations for these children was an inappropriate response.
