Psychology researchers observed that parents feel emotion while singing to their infants. The researchers hypothesized that this emotion noticeably affects the sound of the singing. To test this hypothesis the parents were recorded while singing to their infants and while singing with no infant present. They were instructed to make the two renditions as similar as possible. These recordings were then played for psychologists who had not observed the recordings being made. For 80 percent of the recordings, these psychologists were able to correctly identify, by listening alone, which recordings were of parents singing to their children. The researchers concluded that their hypothesis was correct.
Which one of the following, if true, would most strengthen the researchers' reasoning?
(A) A separate study by the same researchers found that parents feel more emotion when singing to their own children than when singing to other children.
(B) Some, but not all, of the parents in the study realized that their song renditions were being recorded.
(C) Parents displayed little emotion when singing with no child or adult present.
(D) When a person feels emotion, that emotion provokes involuntary physiological responses that affect the vocal cords and lungs.
(E) Most of the parents who participated in the study believed that the emotion they felt while singing to their infants affected their singing.

The argument is that: "this emotion noticeably affects the sound of the singing"
(A) A separate study by the same researchers found that parents feel more emotion when singing to their own children than when singing to other children.
The argument focuses on the difference between the sound of the singing with or with no infant present. The argument doesn't care about whether infants are their own children.
(B) Some, but not all, of the parents in the study realized that their song renditions were being recorded.
This choice is irrelevant to the argument
(C) Parents displayed little emotion when singing with no child or adult present.
This choice could be a contender. However, "adult present" seems irrelevant here.
(D) When a person feels emotion, that emotion provokes involuntary physiological responses that affect the vocal cords and lungs.
Correct. This choice is an evidence that supports the argument.
(E) Most of the parents who participated in the study believed that the emotion they felt while singing to their infants affected their singing.
Belief doesn't necessarily prove that a hypothesis is true.

broall I would disagree with your reasoning about A. Indeed, the argument does not talk about other infants / children. However, it is a stretch to assume that "the argument doesn't care about whether infants are their own children". The argument only talks about "parents and their infants", so the argument actually cares about only one category of children, that is, children for whom their parents are singing. The parents who sign to some "other" children are not in the scope of the argument.
So, it seems to me that A should be ruled out because of the other reason. Specifically, Answer A simply restates what has been given in the stimulus, i.e. the sound of the song changes when "parents sing to their infants". We already know that fact from the stimulus. In other words, option A does not provide any new information.
nightblade354, what are your thoughts on the above?
