### HideShow timer Statistics

In a recent study of arthritis, researchers tried but failed to find any correlation between pain intensity and any of those features of the weather—humidity, temperature swings, barometric pressure—usually cited by arthritis sufferers as the cause of their increased pain. Those arthritis sufferers in the study who were convinced of the existence of such a correlation gave widely varying accounts of the time delay between the occurrence of what they believed to be the relevant feature of the weather and the increased intensity of the pain. Thus, this study _______.

Of the following, which one most logically completes the argument?

(A) indicates that the weather affects some arthritis sufferers more quickly than it does other arthritis sufferers
(B) indicates that arthritis sufferers’ beliefs about the causes of the pain they feel may affect their assessment of the intensity of that pain
(C) suggests that arthritis sufferers are imagining the correlation they assert to exist
(D) suggests that some people are more susceptible to weather-induced arthritis pain than are others
(E) suggests that the scientific investigation of possible links between weather and arthritis pain is impossible

In a recent study of arthritis, researchers tried but failed to find any correlation between pain intensity and any of those features of the weather—humidity, temperature swings, barometric pressure—usually cited by arthritis sufferers as the cause of their increased pain. Those arthritis sufferers in the study who were convinced of the existence of such a correlation gave widely varying accounts of the time delay between the occurrence of what they believed to be the relevant feature of the weather and the increased intensity of the pain. Thus, this study _______.

So, researchers tried to find correlattion betwwen pain intensity and other external factors like weather. Why the researchers decided to conduct the reasearch ? because, SOME arthritis sufferers beleived so. But eventually the correlation gave such widely varying results in terms of delay between the pain occurence and the weather, that they research turned out to be ineffective. Thus, this study _______.

Of the following, which one most logically completes the argument?

(A) indicates that the weather affects some arthritis sufferers more quickly than it does other arthritis sufferers (the reasearch failed. FALSE INFO)

(B) indicates that arthritis sufferers’ beliefs about the causes of the pain they feel may affect their assessment of the intensity of that pain ( nah, it is not true their perception of beliefs about the cause doesnt affect intensity of pain)

(C) suggests that arthritis sufferers are imagining the correlation they assert to exist ( CORRECT. It is quite logical, because this information strengthes the claim that research didnt have any result. In other words, failed. Also since sufferers were CONVINCED, this means they were imagining)

(D) suggests that some people are more susceptible to weather-induced arthritis pain than are others (the reasearch failed. FALSE INFO)

(E) suggests that the scientific investigation of possible links between weather and arthritis pain is impossible (the reasearch failed. FALSE BUT WE CANT CONCLUDE THAT links between weather and arthritis pain is impossible )

(A) indicates that the weather affects some arthritis sufferers more quickly than it does other arthritis sufferers

This implies that the research is failed and whatever people say is actually true. But we have no information in the statement that says research has failed and people succeed. It just says it could not find a correlation. - INCORRECT

(B) indicates that arthritis sufferers’ beliefs about the causes of the pain they feel may affect their assessment of the intensity of that pain

This is a close answer. We certainly know from the statements that it is just an imagination, but I see the usage of may, means possibility. We can keep this for now and move on.

(C) suggests that arthritis sufferers are imagining the correlation they assert to exist

This is a perfect choice. Since they are already imagining that its happening, they are able to say that weather affects pain. But the time delays happen because it is not a fact and varies according to the person's imagination.

(D) suggests that some people are more susceptible to weather-induced arthritis pain than are others - This also means people are correct and scientists failed
(E) suggests that the scientific investigation of possible links between weather and arthritis pain is impossible - This can't be inferred from the statement. We are talking about the relation, not if we can prove it

Hey bb, GMATNinja, Is my reasoning correct?

It was tough between B and C.

Here's where that classic Critical Reasoning precision-in-language is so key. (B) says that these sufferers are mistaken about the intensity of the pain, while (C) says that they're mistaken about the correlation between these weather events and the pain. So these two potential conclusions are about similar but significantly different things: intensity vs. correlation.

If you to back to the key fact in the argument that suggests that these people are mistaken, it says that they gave widely varying accounts of the time delay between weather events and pain intensity. This is about the correlation - did the weather impact the pain or did it not? It's subtle, but that's the big difference between (B) and (C).

Complete Question Explanation

Main Point-FIB, CE. The correct answer choice is (C)

In a recent study of arthritis, researchers failed to find a correlation between arthritis pain and the weather conditions most commonly associated with such pain. What they found was that arthritis sufferers who were convinced of the existence of such a correlation gave widely varying accounts of the time delay between the occurrence of the weather condition and the increased intensity of the pain.

The question stem asks you to fill in the blank with an appropriate answer. While this is not one of the most common question types on the test, Fill in the Blanks almost always indicate the presence of a Main Point question. Note that the placement of the blank is at the very end of the stimulus, and the sentence it completes begins with the conclusion indicator “thus.” Therefore, you should fill the blank with the answer choice that best represents the main point of the argument. To achieve this goal, look for contextual clues in the stimulus revealing the direction of the argument and the author’s intent.

The first two sentences, when taken together, contain all the information required to fill in the blank at the end of the question. From the outset, the author rejects the existence of any correlation between the intensity of arthritis pain and the weather conditions commonly associated with increased pain. Immediately after, she describes inconsistencies in the accounts given by arthritis sufferers who believed in such a correlation. Clearly, the author feels that no causal link exists between weather conditions and arthritis pain, and that the arthritis sufferers are mistaken in their beliefs about such a correlation. The last sentence then prefaces the blank by saying, “thus, this study______.” The most logical answer would be one suggesting that the arthritis sufferers’ beliefs are unfounded.

Answer choice (A): Although this answer choice describes a plausible hypothesis given the varying accounts of the time delay between the occurrence of the weather condition and the increased intensity of the pain experienced by arthritis sufferers, it ignores the assertion made in the beginning of the stimulus—researchers found no correlation between pain intensity and weather conditions. Therefore, the weather need not affect arthritis sufferers at all, despite any beliefs to the contrary. Because this answer choice fails the Fact Test, it is incorrect.

Remember—Main Point questions are a subcategory of Must Be True questions and thus fall into the First Family of question types. The correct answer choice must be true according to the stimulus (and also summarize the author’s point).
Answer choice (B): This answer choice suggests that arthritis sufferers’ beliefs about the causes of the pain they feel may affect their assessment of the intensity of that pain:

Cause ..... ..... ..... ..... ..... ..... ...... ..... ..... Effect

Beliefs about causes of pain ..... -> ..... Arthritis pain

However, just because the study rejects the notion that weather conditions affect arthritis pain does not mean that one’s beliefs about the causes of arthritis pain affect the intensity of such pain. The study provides no comparison of the pain intensity or delays experienced by believers and non-believers—the information we have pertains only to the inconsistent accounts given by those who believe that weather affects their pain. Had the study revealed that those convinced of the existence of a correlation experienced pain differently than those who were not so convinced, this would have been a useful comparison to support the conclusion in answer choice (B).

Answer choice (C): This is the correct answer choice. Given the researcher’s failure to find any correlation between weather conditions and arthritis pain, those still convinced of such a correlation must be mistaken in their beliefs.

Answer choice (D): Given that the study found no correlation between the intensity of arthritis pain and weather conditions, there is no proof that weather-induced arthritis pain actually exists. Therefore, it would be unreasonable to conclude that some people are more susceptible to such pain than are others.

Answer choice (E): Just because one study found no connection between weather and arthritis pain does not mean that scientific investigation of such a connection is impossible. This answer choice exaggerates the facts and makes a broader statement that is not supported by the stimulus.
