Most mental health disorders and cases of drug abuse tend to diminish a person’s ability to recognize other people’s feelings. A recent study in Norway suggests, however, that these effects can be bolstered by a nasal spray puff of the brain hormone oxytocin, which is known to increase feelings of calm and social bonding. Although oxytocin is already prescribed for certain disorders that affect social function, such as autism, these treatments are often tried in isolated cases, leaving the overall effects of the drug without evaluation.

The Norwegian experiment focused on 40 students, each of whom was given either a control dose of salt water or the drug oxytocin. After the nasal dose, the students were shown faces of happy, angry, or neutral expressions, some of which were subtler than others. The researchers found that after a nasal spray dose of oxytocin, the students’ awareness of the expressions was intensified. Further, the experiment showed that the oxytocin had the greatest effect on those who were least able to evaluate emotions properly when given the control.

Although the results of this study seem promising, Leknes, the lead scientist in the investigation, cautions that the hormone would not be a “cure-all” for mental illness or drug addiction. Rather, he suggests, the hormone might help some individuals better interpret the social cues from the world around them.

For question 3, I was unable to eliminate answer choice 'C'. I guess option C is implied but as per the question it asks us "not mentioned in the passage".

(A) The study showed that oxytocin made students more able to distinguish faces from one another.
(C) A control dose of salt water was used to gauge normal student ability to recognize facial expressions.

3. Which of the following is not mentioned in the passage regarding the Norwegian study on oxytocin?

Difficulty Level:   700

Explanation

The experiment was related to students’ ability to recognize emotions from facial expressions, not their ability to tell faces apart. Therefore,  (A)  is the correct answer.

Choice (B)  is mentioned in the first sentence of the  last paragraph  of the passage.

Choice (C)  is addressed throughout the second paragraph, first when it is stated that  “a control dose of salt water”  was given, and then when awareness after exposure to oxytocin is compared to awareness after the controlled salt water dose.

Choice (D)  is explicitly stated in the second sentence of the  second paragraph.

Finally,  choice (E)  is explicitly addressed in the last sentence of the  second paragraph.

Answer: A

2. The passage lends the most support to which of the following conclusions about the nasal spray study of oxytocin?

Difficulty Level:   700

Explanation

The  second paragraph  states that  “the experiment showed that the oxytocin had the greatest affect on those who were least able to evaluate emotions properly when given the control.”  Thus, it can be inferred that those with the least ability to naturally infer emotions, in other words, the ones who might need it most, reaped the greatest benefits of the hormone. This matches  choice (D) .

Additionally,  (A)  is incorrect as the passage does not discuss inconclusiveness based on sample size.

Choice (B)  is incorrect as it incorrectly pairs the known effects of the hormone in the brain with the results of the student study.

Choice (C)  is incorrect as the passage does not address the ability of the students to recognize expressions, just the relative change between the controlled salt water dose and the oxytocin.

Finally,  choice (E)  is incorrect for a similar reason: the passage does not state that the subtler the expression the more difficult it was for students to identify, just that some expressions that were used were subtler than others.

Answer: D

I have one question regarding the following last sentence of the 2nd paragraph, 
"Further, the experiment showed that the oxytocin had the greatest effect on those who were least able to evaluate emotions properly  when given the control ."

What words are omitted in "when given the control" ? When (those who ... were) given the control (dose of oxytocin) ?

Thank you !

Need help with Q1!how is C wrong

Posted from my mobile device

LamboWalker · Answer

(C) It is  NOT  useful for people who are already able to interpret social cues.

The usage of not tells us that this experiment was useless for people who were already able to interpret clues. But is that true based on the passage? Certainly no. The last line of the second paragraph tells us that this experiment had the  greatest  effect on those who weren't able to interpret social emotions. This indicates that the drug also had some effect on others too, we are just not sure how much of it.

On the other hand, last line of first paragraph clearly gives us the right answer i.e. Option A.

Sajjad1994 · Answer

Official Explanation

1. The author of the passage would most likely agree with which of the following statements about the brain hormone oxytocin?

Difficulty Level:   600

Explanation

The  first paragraph  of the passage states that oxytocin treatments are often tried in isolated cases and the overall effects are without evaluation. The passage then describes a small study that seems promising but makes no definitive claims. Therefore, it is likely that the author would agree that the effects of oxytocin require further evaluation, supporting  choice (A).

Answer  choice (B)  is incorrect as the passage states the opposite, namely that oxytocin is not a  “cure-all.”  Although the author focuses on the effects of oxytocin for those who are not able to interpret social cues, answer  choice (C)  is incorrect as the author does not state that the drug would not be useful for those who can already do so. The author specifically addresses  choice (D)  in the passage, stating that the hormone oxytocin increases feelings of calm and social bonding.

Finally, answer  choice (E)  is incorrect, as the author never addresses oxytocin as an oral treatment.

Answer: A

abhishektyga · Answer

In Q3 option C mentions normal students but it was nowhere mentioned in the RC.
So shouldn't C be the answer instead of A?

(C) A control dose of salt water was used to gauge normal student ability to recognize facial expressions.

bM22 · Answer

Hi  abhishektyga ,

Option C can be inferred from the lines: "The Norwegian experiment focused on 40 students, each of whom was given either a control dose of salt water or the drug oxytocin. After the nasal dose, the students were shown faces of happy, angry, or neutral expressions, some of which were subtler than others."

Hope This Helps.
Thanks.
