Hello, everyone. This sort of fill-in-the-blank question type was more common in the past, but regardless of how a question is pitched to us, we still need to focus on just what the passage lays out. What does this one have in store?

Sentence one tells us  what  the NIH is doing:  funding research... to help scientists identify the neural circuits involved in attention and selection .   Sentence two zooms in, focusing on  the researchers  conducting the research—they are studying a phenomenon  known as the "cocktail party effect."    Sentence three provides information on  certain psychiatric disorders  that people may possess in which their ability  to select what deserves attention and what does not  is hampered.

Our goal is to determine what  the NIH most likely believes  in choosing to fund this line of research. As always, it is vital to keep both the question frame and the passage in mind when assessing the answer choices.

Remember, the  researchers  are interested in this phenomenon. It is possible that the NIH is not even aware of such a term. Besides, we cannot be expected to conclude that just because something has been researched (or even  explained ) before, the topic is unworthy of further study. This may be an easy answer to fall for if you have not practiced CR too much, but for the initiated, it should be apparent that there are too many logical gaps to fill.

There must be  some  reason that mice and owls were selected for the experiments, right? But would the NIH look at an experimental design and conclude that  because  mice and owls might possess the above abilities, the research was worth funding? It seems, again, as though  the researchers  selected these animals for some reason, and that the NIH is merely placing trust in the researchers. The word  comparable  is also suspect. It could be the case that one animal possesses better-than-human "cocktail party" abilities while the other may serve as nothing more than a control. We are not privy to information on the selection process. On first look, this answer choice can look promising. I might keep it in my first pass of the options. But the goal is always to choose the least debatable of the five answers presented, and I have my doubts about this one.

Now the focus is back on the NIH, just where it should be to answer the question at hand. The first line of the passage tells us outright that the NIH is  funding research on mice and owls to help scientists identify the neural circuits involved in attention and selection . If these  circuits  or  pathways  were  not  detectable, then we would have no compelling reason to believe the NIH would be willing to foot the bill for such research. This looks like a better option than (B) above.

Although the soft language in  may be  should not go unnoticed,  a cure  is definite, like the "off" of a light switch. The  goal  may be to find a cure, and the NIH may very well  hope  that such a cure will be found through this research avenue, but does the passage allow us to point to a given line to justify this statement as our answer? We should not have to furnish an explanation for what could be true; we want to get behind an option that follows from the information provided. Again, I would not call this a terrible answer. It just does not quite add up.

All we know is that the passage indicates that the NIH is funding a certain type of research. We cannot speculate on why it would or would not choose to fund other types. Probably the easiest of the five answer choices to eliminate, in my view.

I hope that helps clear any confusion on this one. Enjoy the competition, everyone.

In allocating funds for the research outlined in the passage, the NIH most likely believes __________.

(A) that previous research has not already explained the “cocktail party effect”
Maybe the effect has already been explained or not. It does not matter. Irrelevant. Incorrect.

(B) that mice and owls possess neurological abilities comparable to those of humans to select an auditory stimulus from among many such stimuli
The problem with this is when it says "comparable to those of humans". We don't know from the questions it they are comparable or not. Incorrect.

(C) that the neurological pathways involved in auditory attention and selection are detectable
 This is the correct one. They want to identify the neural circuits involved in attention and selection, so they think that those circuits are detectable.

(D) that a cure for psychiatric disorders such as ADHD, autism, and schizophrenia may be found through such research
We can not deduce this from the text. Incorrect.

(E) that similar research conducted on humans would be unethical
Irrelevant.

Option C.

(A) that previous research has not already explained the “cocktail party effect” = That is not necessarily true. this can be an enhancement of previous research. Incorrect assumption. 
(B) that mice and owls possess neurological abilities comparable to those of humans to select an auditory stimulus from among many such stimuli = this may be true but is not the crux of the passage. the passage is concerned with finding the path of selection and attention of brain. Incorrect usage. 
(C) that the neurological pathways involved in auditory attention and selection are detectable = Correct usage. It identifies crux of the passage. 
(D) that a cure for psychiatric disorders such as ADHD, autism, and schizophrenia may be found through such research = Cure is not the crux of the passage. Incorrect usage. 
(E) that similar research conducted on humans would be unethical = No mention of ethics and out of scope. incorrect usage.

(E) that similar research conducted on humans would be unethical

So, NIH is funding research on the identification of the neural circuits involved in attention and selection. Mainly because the National Institutes of Health believes neural circuits are identifiable, otherwise, it would not finance the research. So, answer choice C gives us this idea. The correct answer is C.

Archit3110 · Answer

Conclusion of argument : the NIH, is funding research on mice and owls to help scientists  identify the neural circuits involved in attention and selection 
Premise: researchers are studying  what is known as the “cocktail party effect,”  the ability of the brain, when exposed to multiple auditory stimuli, to select what deserves attention and what does not.

People with certain psychiatric disorders, including ADHD, autism, and schizophrenia, are known to  lack this neurological ability.

we need to find assumption basis of the argument , apply negation test and weaken the conclusion

(A) that previous research has not already explained the “cocktail party effect”
 that previous research has already explained the “cocktail party effect” ; this is not weakening the conclusion

(B) that mice and owls possess neurological abilities comparable to those of humans to select an auditory stimulus from among many such stimuli
that mice and owls  do not   possess neurological abilities comparable to those of humans to select an auditory stimulus from among many such stimuli ; this cannot be correct as the premise correctly states that  The researchers are studying what is known as the “cocktail party effect,” the ability of the brain, when exposed to multiple auditory stimuli, to select what deserves attention and what does not  which is being done on mice and owls ; incorrect

(C) that the neurological pathways involved in auditory attention and selection are detectable
that the neurological pathways involved in auditory attention and selection are  not  detectable ; this weakens the conclusion ; correct option

(D) that a cure for psychiatric disorders such as ADHD, autism, and schizophrenia may be found through such research ; argument is not discussing about finding a cure ; wrong option

(E) that similar research conducted on humans would be unethical ; no mention about ethical or unethical practise

option C is correct 
 that the neurological pathways involved in auditory attention and selection are detectable

In allocating funds for the research outlined in the passage, the NIH most likely believes __________.

Inference type question:
 (A) that previous research has not already explained the “cocktail party effect”  Irrelevant

(B) that mice and owls possess neurological abilities comparable to those of humans to select an auditory stimulus from among many such stimuli  The comparison is not required for the conclusion to hold good. So incorrect.

(C) that the neurological pathways involved in auditory attention and selection are detectable 
 If this is not detectable then there is on analysis. So it shatters the entire argument

(D) that a cure for psychiatric disorders such as ADHD, autism, and schizophrenia may be found through such research  OFS doesn't impact the argument

(E) that similar research conducted on humans would be unethical  OFS, doesn't impact the argument

In allocating funds for the research outlined in the passage, the NIH most likely believes __________.

Based on the information, we need to find what NIH believes so that they can fund scientists to identify the neural circuits involved in attention and selection. We need to find answer choice what do the NIH believe? What was the NIH conviction?

(A) that previous research has not already explained the “cocktail party effect”
 "cocktail party effect" is a study on ability of brain to select what needs attention & what does not . The fund is for identifying neural circuits involved in attention & selection . 
(B) that mice and owls possess neurological abilities comparable to those of humans to select an auditory stimulus from among many such stimuli
 This can be an assumption and not the conviction.  
(C) that the neurological pathways involved in auditory attention and selection are detectable
 This makes a perfect sense. Only if NIH believes neurological pathway is detectable, then NIH will be willing to fund the scientist to research on identifying them. 
(D) that a cure for psychiatric disorders such as ADHD, autism, and schizophrenia may be found through such research
 It is clearly stated that subjects with psychiatric disorders lack neurological ability. So, funding to to help scientists identify the neural circuits involved in attention and selection, will not help to cure psychiatric disorders. It is only for identification and not for the cure.
 
(E) that similar research conducted on humans would be unethical
 This is out of scope.

So the answer choice is C.

Answer C

samarpan.g28 · Answer

Just because the last line "People with certain psychiatric disorders, including ADHD, autism, and schizophrenia, are known to lack this neurological ability." mentions people and their psychiatric disorders, that does not mean they are neurologically related to owls and mice. Option C is wrong. However, the research is conducted because they are sure that the readings of the experiment are detectable. Option C is correct.
