Scientists have long searched for magnetic monopoles, hypothetical particles left over from the Big Bang. In 1982, a detector at Stanford recorded a single event that seemed to be the passage of a monopole. However, despite the fact that the Stanford experimental design has withstood all serious challenges, no other detectors have ever recorded similar events. Even though one team of physicists has recently claimed to have found indirect evidence that magnetic monopoles must exist, the consensus of the physics community is that monopoles, if they do exist, have not yet been discovered.

In the argument above, the two portions in boldface play which of the following roles?

(A) The first is a difficulty that contradicts the status quo view of the majority of physicists; the second is that status quo view.

(B) The first is a comment that supports a minority position among physicists; the second is an alternative to that minority position.

(C) The first is evidence strengthening an unrepeated experimental result; the second is a claim supported by that evidence.

(D) The first is an assertion that undermines a hypothesis commonly thought to be unproven; the second is that hypothesis.

(E) The first is a corroboration of an assertion that lacks experimental support; the second is that assertion.

option D

hi soumen4u.. why dont you explain your views.. the OA is already posted and by the way option C is the correct answer, if you list out your reasoning , it would benefit others and hopefully yourself also..

OA: EXPLANATION MUST.

It's D because no one else besides the team has discovered the monopoles although they do exist. Now typically if one were to prove something it will be gone through questioning and testing and the team did that and passed them all. So since there's no way to disprove the fact that the team has discovered monopoles, the discovery undermines the fact that the hypothesis is unproven.

C, because the claim is that the particle exists, and the first part is just some evidence that does not DIRECTLY support the claim, but it does support the experiemental result...which in turn supports the claim...

so it's like machine never failed(the evidence that support the result)---supports the results's validity--->saw the particle passing(result that support the claim)-----suggest the particle exists--->particle does exist (the claim)

Agree with C

Here is the explaination

Premise :Scientists have long searched for magnetic monopoles, hypothetical particles left over from the Big Bang.
Conclusion :In 1982, a detector at Stanford recorded a single event that seemed to be the passage of a monopole.
Premise :However, despite the fact that the Stanford experimental design has withstood all serious challenges, no other detectors have ever recorded similar events.
Counter Premise :Even though one team of physicists has recently claimed to have found indirect evidence that magnetic monopoles must exist, the consensus of the physics community is that monopoles, if they do exist, have not yet been discovered.

Once you break down the argument , you can see that C fits nicely as answer

D is wrong as there was an Experiment in which the particles were recorded

Nice one +1! My answer is C.

Scientists have long searched for magnetic monopoles, hypothetical particles left over from the Big Bang. In 1982, a detector at Stanford recorded a single event that seemed to be the passage of a monopole. However, despite the fact that the Stanford experimental design has withstood all serious challenges, no other detectors have ever recorded similar events. Even though one team of physicists has recently claimed to have found indirect evidence that magnetic monopoles must exist, the consensus of the physics community is that monopoles, if they do exist, have not yet been discovered.

c.The first is evidence strengthening an unrepeated experimental result;
the Stanford experimental design has withstood all serious challenges is infact evidence that support the experiment: no one has been able to weaken the experiment so far.
the second is a claim supported by that evidence.
magnetic monopoles must exist is a claim supported by the experiment. "A detector at Stanford recorded the passage of a monopole" => monopoles must exist.

IMO D is wrong
d.The first is an assertion that undermines a hypothesis commonly thought to be unproven (hypothesis ="monopoles must exist"); the second is that hypothesis .
The first part support the hypothesis. My 2 cents...

Surely...wonderful question....I would like to go with C.....

I used POE:-
A. The second is support fr the minority proponents...its nt the status quo...
B. Second is not alternative...it furthers the point mentioned in first bold face.
D. The first does not undermines anything.
E. Experimental position for first discussed extensively...so cannot conclude that it lacks the experimental proof.

Consider Kudos If my post helps!!!!!!111

Yeah ..Now i can understand why D is wrong...But still I have a doubt in C.
C tells that: 'second is a claim supported by that evidence': but from the premise: "physicists has recently claimed to have found indirect evidence that magnetic monopoles must exist"

So they have claimed on the basis of that experiment but from some other evidence.

still not very clear why E is wrong

OA:

This question is an Analyze the Argument Structure question. The best approach is to identify the conclusion of the argument, to characterize how each boldface statement relates to that conclusion, and then to eliminate incorrect answer choices. The conclusion of the argument is the consensus view of the physics community that monopoles have not yet been discovered, whether or not they exist. The first boldface is a premise opposing that conclusion, since the first boldface supports the experiment that recorded the presence of a monopole. The second boldface is the minority view that monopoles are certain to exist. Thus, the first boldface supports the second.

(A) The first boldface does in fact contradict the status quo view of the majority of physicists, i.e. that monopoles have not yet been discovered. However, the second boldface is not that status quo view, but in fact the minority view.

(B) Just as in answer (A), the first boldface does support a minority position among physicists, but the second boldface is not an alternative to that minority position – it is that minority position.

(C) CORRECT. The first boldface provides evidence in support of an unrepeated experimental result: since “no other detectors have ever recorded similar events,” the Stanford experiment’s result is unique. The second boldface makes the claim that monopoles must exist. This claim is supported by the Stanford experiment and thus by the first boldface.

(D) The first boldface does not undermine a hypothesis that most physicists think is unproven. Rather, the first boldface supports the hypothesis, as yet unaccepted by most physicists, that monopoles must exist. The description of the second boldface as that hypothesis is accurate.

(E) The first boldface does not corroborate an assertion that lacks experimental support, since the assertion that monopoles must exist does have support from the Stanford experiment. The description of the second boldface as that assertion is accurate.

Best way to solve these types of questions is by noting which bold faced part is a fact and which one is an opinion.

The first is evidence strengthening an unrepeated experimental result; the second is a claim supported by that evidence.

Only C says that first one is a fact/evidence. Second is obviously a claim.

C is right!
