+1 for E,but D also seems tempting as it implies that there was not actually any dearth of particle accelerators to do the experiment and publish the article thus there may be another reason for the low number of articles.

I also have had a hard time deciding between between (D) and (E).

(D) If particle accelerators can be used for more than one group of experiments in any given year, then the drop of the availability of accelerators due to their repairs could be offset by using available accelerators more.

(E) I dismissed this choice for two reasons:

1) The stimulus talks about articles reporting results of experiments involving particle accelerators; whereas (E) talks about articles concerning patricle-accelerator research, which IMO is not the same. And the reason I think these two are not the same is because particle accelerator research IMO studies accelerators, and experiments involving particle accelerators are concerned with behavior of particles in accelerators. E.g., (E) talks about CERN (European Laboratory for Particle Physics), stimulus talks about a research at one of CERN's accelerators.

2) Additionally, (E) talks about recent changes in editorial policies. The stimulus talks about events that are two years old.

Maybe I'm overthinking this one too much and maybe both underlined phrases are just the same. Maybe recent means two years ago. But anyway, I strongly think that (D) is a valid answer and not anywhere inferior to (E).

Here's OG's explanation (BTW it's Q83 from OG12):

(D) If the accelerators can be used for multiple experiments, then it is reasonable to expect more articles related to them, not fewer.

Now, I don't know why we can infer that. Since some accelerators were out of service, then it is reasonable to assume that even though accelerators can be used to process more than one experiment, the workload on working accelerators would increase thereby not allowing the overall number of experiments to increase.

Any thoughts?

For those who are interested, here's why (D) is a wrong answer:

The effect: There were fewer articles reporting the results of experiments involving particle accelerators.

The stated cause (the one we should attack): Some accelerators were unavailable for research.

To refute the cause and effect relationship we need to, for example, find an alternative cause.

(D) doesn't accomplish this because had it been true that other functioning accelerators were available for multiple experiments, the effect would have never occurred in the first place. Well of course if those accelerators hadn't been already used at their full capacities. But even if that were the case, (D) still wouldn't be a great alternative cause of the decline in the number of published articles.

(E) provides an alternative explanation of the stated effect.

The only thing that still bothers me is the word 'lately' in (E). But all in all (E) is a clear winner now.

I for one moment though about D but few particle accelerators should not hamper the articles presented but if the publication is against printing such articles then the number of such articles will definitely decline,as a result I chose E.

Which of the following, if true, most seriously undermines the journalist’s argument?
(A) Every article based on experiments with particle accelerators that was submitted for publication last year
actually was published.
(B) The average time scientists must wait for access to a particle accelerator has declined over the last
several years.
(C) The number of physics journals was the same last year as in previous years.
(D) Particle accelerators can be used for more than one group of experiments in any given year.
(E) Recent changes in the editorial policies of several physics journals have decreased the likelihood that
articles concerning particle-accelerator research will be accepted for publication.

OA will be given tomorrow.


If You Like the question Consider KUDOS


conclusion : the decrease in number of publication last year was due to unavailability of particle accelerator.
premise 1/ reason : several particle accelerators were out of service


to weaken this argument/conclusion lets look out for an alternate reason leading to conclusion. this is exactly wht option E does, it shows decrease is due to changes in editorial policies.

i too am stuck between E and D. can someone explain this properly?
IMO E says particle accelerator research which is not same as stimulus which says research involving particle accelerator. and D seems to negate the reason that low availability of accltrs is the cause.

D- even if particle accelerators can be used by multiple groups, they didn't state how many groups there are and how many particle accelerators there are. perhaps if the ratio changed, then maybe we could consider this, but even in the premises they never excluded the possibility of sharing.

B- this one seemed trickier to exclude.. if the time scientists wait is decreasing, one would assume that it can't be the accelerators being broken causing the lower articles.. ie scientists have even faster access. but what if the fact that the accelerator is broken, many groups don't even bother pursuing their experiment and move onto other things. then they technically have zero wait.

say there are 4 researchers waiting 1 day to use a machine, then say the machines are improved so the researchers only have to wait 1/2 day (ans B), well there are still only 4 articles published, although faster perhaps

with E, if their articles aren't even published, then it shows the wait time has no effect on the number of articles.

what threw me off was the present/future tense of the answer E - "recent changes" and "will be accepted for publication", considering that the question talks about "last year". I automatically assumed that these recent changes couldn't have any effect on articles published last year. Has anyone else noticed it?

The best way to answer this is to determine the parts of the argument:

Premise: In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years.

Premise: Several of the particle accelerators at major research institutions were out of service the year before last for repairs.

Conclusion: It is likely that the low number of articles was due to the decline in availability of particle accelerators.

In here we could see that causation. Simply put: Out of service particle accelerators ----> Low number of articles

The question is asking us to undermine (weaken) the argument. We know that one of the ways to weaken an argument is to introduce another cause to the intended effect.

This is the reason why D is the answer. D provides us another cause that 'caused' the effect. The importance of determining the parts of the argument is that it helps us determine which among the answer choices 'destroys' the conclusion. In this case, D totally demolishes it.

I chose B, because B tells us that scientists actually had more availably to the particle accelerators bc of decreased wait time. Shouldn't this weaken the argument? Thanks!

My take on this one is pretty similar to the take I had on the Baseball Paradox problem, see baseball-paradox-139713.html#p1126348

The short version is that any time you have a premise that describes some phenomenon and a conclusion that attempts to explain that phenomenon, you should look for alternate explanations.

Since this is a Weaken problem we want an answer that provides one such alternate explanation.

Here, the phenomenon (given as a premise) is that fewer papers were published this year, and some accelerators were down recently. The explanation (conclusion) is that the downtime for the accelerators caused the decrease in published papers. We're looking for an answer choice that would result in a decrease in published papers but has nothing to do with the accelerator down time. Only (E) even comes close to accomplishing this!

The real take-away for this problem (as well as the Baseball Paradox) has nothing to do with the specific problems but rather is about how you should study for Assumptions Family question types on CR. Look for patterns and categories of assumptions and try to generalize everything you do. This will make you much more efficient at brainstorming assumptions and before you know it you'll be accurately predicting most of the correct answers on these problems.

Cheers,
Mark

I don't see why D couldn't be chosen. E refers to "recent changes" and says that these recent changes *will* affect publication in the future. However, the prompt is talking about a trend that already happened and refers to events that are 1-2 years old, not recent. Why would a change in editorial policies that occurs after the trend affect the amount of articles published last year?

I think D makes sense because if particle accelerators can be used by multiple people in a year, then scientists who would have used the now-broken accelerators can now double up on the working ones. This means that there is not a decline in availability of particle accelerators, so the decrease in articles would have had to come from another source.

Can anyone explain this? The OG guide and the MGMAT video explanation don't even address these concerns.

I also got stuck between D and E, chose D.

"The journalist assumes that lack of access to accelerators is the main reason..."

Undermining this statement option D correctly points out that there cant be any shortage because it can be shared by more than one group....So the reason of declining is something else....

E must be the answer.

Conclusion: the low number of articles was due to the decline in availability of particle accelerators.

(D) Particle accelerators can be used for more than one group of experiments in any given year.


Choice D tells us that particle accelerators can be more effectively used to publish more number of articles. But it is not what the conclusion of the argument is concerned about. The right answer must find an alternative reason for the low number of articles.

Hi!

Can someone pls explain why the correct answer is not D.

I thought if these accelerators can be used for more than one group of experiments then the lack of these accelerators cannot be seen as a reason for the decline of these articles. And that is clearly a flaw in the argument.
