To solve this question, let us deploy
IMS's four-step technique.
STEP #1 ->
IDENTIFY THE QUESTION TYPE BY READING THE QUESTION STEMThe question stem states, 'Which of the following, if true, would most weaken the argument made above about the group's approach?' Clearly, we are dealing with a weakening question. Now that the question type is identified, let us proceed to the second step.
STEP #2 ->
DECONSTRUCT THE ARGUMENT In a weakening question, it is a must to deconstruct the argument by figuring out the conclusion and the premise(s) on the basis of which the conclusion is drawn.
CONCLUSION: There is a flaw in the strategy of the group of scientists who have studied schizophrenia in an isolated community in Costa Rica with the objective of learning about the causes of schizophrenia worldwide.
PREMISES: -> Schizophrenia is characterized by the way emotional responses are learned, and the way emotional responses are learned may differ across cultures of the world.
-> On what is now a largely interconnected planet, a schizophrenic in an isolated community is a schizophrenic of no practical interest.
Now that the argument is deconstructed, let us proceed to the third step .
STEP #3 ->
FRAME A SHADOW ANSWERIn a weakening question, the right answer must weaken the conclusion of the author. The right answer here must therefore give us a situation that states the approach adopted by the group of scientists is actually not flawed. An effective way of weakening the conclusion is by showcasing a situation that states studying schizophrenics in the isolated community is going to help them achieve their goal by learning about the causes of schizophrenia worldwide.
SHADOW ANSWER: A situation that tells us that the strategy adopted by scientists is not flawed by showcasing how studying schizophrenics in the isolated community is going to help them achieve their goal of learning about the causes of schizophrenia worldwide.
Now that a shadow answer is framed, let us proceed to the final step.
STEP #4 ->
ELIMINATE INCORRECT ANSWER OPTIONSAll answer options that do not match the shadow answer can be eliminated.
A. All schizophrenics have certain features in common which, if studied, would help scientists to learn about the causes of schizophrenia in general. -
ALIGNS WITH THE SHADOW ANSWER /WEAKENS -
Our right answer must prove why the strategy is not flawed. This option tells us how studying the schizophrenics in the isolated community could still help the scientists achieve their goal of learning about the causes of schizophrenia in general. The author's conclusion is weakened. -
KEEPB. Living in an urban environment during childhood or as an adult doubles the risk of schizophrenia in an individual. -
NOT A MATCH -
The right answer should tell us how the scientists would be able to meet their objectives. This answer option speaks of what doubles the risk of schizophrenia, which is not what we are looking for in the right answer. -
ELIMINATE C. To understand schizophrenia, it is necessary to learn about not just impaired emotional responses, but also paranoid beliefs, hallucinations, and disorganized thinking. -
NOT A MATCH -
Again, does not tell me how the scientists would be able to meet their objective. -
ELIMINATE D. The group of scientists will not draw conclusions about schizophrenics as a whole from their findings in the isolated community. -
NOT A MATCH -
While this tells us what the group of scientists will not do, it does not state how their objective of learning about the causes in general would be achieved by studying the schizophrenics in the isolated community. -
ELIMINATE E. Of the schizophrenics present in the isolated community, more than half have travelled abroad in their adulthood. -
NOT A MATCH -
Again, this option does not state how the objective of the scientists would be achieved by studying the schizophrenics in the isolated community. -
ELIMINATEHence, A is the right answer.
