Critical Reasoning

Question 1
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?

Whether loud rock music can damage the hearing of newborns?

What the average weight of the neonates was before and after the experiment?

Whether the newborns in both nurseries were equally healthy and happy at the start of the experiment?

The musical preferences of the parents of the two groups of newborns?

Whether the music was played in the nurseries at all times or only at certain times ?

Question 2
Which of the following additional experimental data would support the hypothesis that classical music is beneficial to the development of newborn?

The music played in nursery A was louder than that played in nursery B.

The ratio of nurses to newborns in nursery B was 1 to 4; in nursery A, it was 1 to 6.

The newborns in nursery A cried less, suffered fewer minor ailments, and gained more weight than did newborns in a
nursery with no music.

The neonates in a nursery where no music was played fared better than those in nursery B.

Nursery A contained 15 percent more premature babies than nursery B
