(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."
This is incorrect for two main reasons. First, the study in the passage is testing if "emotion noticeably affects the sound of the singing" not just if the singers feel emotion. It is already established in the first sentence that "researchers observed that parents feel more emotion while singing to their infants." Second, the study is only comparing parents singing to their infants with parents singing to no infant. The effect of parents singing to someone else's child is therefore irrelevant. Essentially, (A) is wrong because it does not affect the passage's conclusion.
(D) "When a person feels emotion, that emotion provokes involuntary physiological responses that affect the vocal cords and lungs."
This is correct because it supports the passage's conclusion that emotion noticeably affects the sound of singing, as the researchers hypothesized and confirmed in their study. This answer choice helps to further explain what causes the observable difference in singing noted in the passage.
Does that make sense? Please let us know if you have any other questions!

Could someone explain to me why C is wrong. I Get why D is right but it felt like C was offering an alternative explanation. Thanks.
