The Official Guide for GMAT Review 2018

Practice Question
Question No.: CR643


Here's my insight:
The kinds of hand and wrist injuries that result from extended use of a computer while maintaining an incorrect posture are common among schoolchildren in Harnville. Computers are important to the school curriculum there, so instead of reducing the amount their students use computers, teachers plan to bring about a sharp reduction in the number of these injuries by carefully monitoring their students' posture when using computers in the classroom.

Which of the following would it be most useful to know in order to assess the likelihood that the teachers' plan will be successful?Teacher's plan is to reduce the hand/wrist injuries by monitoring student's posture "in the classroom"

(A) Whether extended use of a computer while maintaining incorrect posture can cause injuries other than hand and wrist injuriesArgument talking/concerned only about hand and wrist inuries. So other injuries are irrelevant.

(B) Whether hand and wrist injuries not caused by computer use are common among schoolchildren in Harnville.Again, arg focuses only on hand and wrist inuries caused by extended use of computers. So irrelevant

(C) What proportion of schoolchildren in Harnville with hand and wrist injuries use computers extensively outside the classroomCorrect. Arg focuses on monitoring posture in the classrooms.What about monitoring outside the classroom?If unchecked then it can lead to more such incidents.If checked then all goes well. Hence this is necessary to evaluate.

(D) Whether changes in the curriculum could reduce the schools' dependence on computersArg clearly states that the teachers will monitor student's posture rather than reduce the amount spent(and the curriculum) on computers. So irrelevant.

(E) What proportion of schoolchildren in Harnville already use correct posture while using a computer.Again, argument focuses on incorrect posture and not on correct posture. Moreover, argument already provides some information on this by saying that cases of hand and wrist injuries are "common" in students.

Harnville Injuries

Step 1: Identify the Question

The words useful to know in order to assess in the question stem indicate that this is an Evaluate the Argument question.

Step 2: Deconstruct the Argument

inj from cmpt use + bad posture

cmpt use needed

Plan: watch posture, will ↓ inj

Step 3: Pause and State the Goal

On Evaluate questions, the goal is to find an answer choice that expresses a question or comparison that would be important to answer or understand in order to evaluate the argument. In this case, you’re asked to evaluate whether the teachers’ plan is likely to be successful.

Step 4: Work from Wrong to Right

(A) The plan is to reduce the number of hand and wrist injuries. Other kinds of injuries are irrelevant to whether this plan will succeed.

(B) Any hand or wrist injuries caused by something other than computer use are not relevant to this particular plan.

(C) CORRECT. Teachers are able to monitor students only when at school. If many students are sustaining these injuries at home, the plan is unlikely to reduce injuries. If, however, most of the injuries are sustained at school, the plan is more likely to succeed.

(D) This answer introduces another possible plan, which may be able to achieve the same goal, but doesn't help to evaluate whether this particular plan would work. In general, a choice that introduces a new plan to try to achieve the same goal will not be the correct answer; the question is asking you to evaluate the plan given in the argument.

(E) Even if a large number of schoolchildren already use correct posture, this plan could help to prevent injuries among those who do not. Moreover, the argument establishes that these types of injuries are common in this school district. Knowing the exact proportion does not help to evaluate whether the plan will help to reduce the incidence of these common injuries among students who are not using correct posture.

Why is E incorrect? Could anyone please explain to me? Would greatly appreciate it!



The kinds of hand and wrist injuries that result from extended use of a computer while maintaining an incorrect posture are common among schoolchildren in Harnville. Computers are important to the school curriculum there, so instead of reducing the amount their students use computers, teachers plan to bring about a sharp reduction in the number of these injuries by carefully monitoring their students' posture when using computers in the classroom.

Premise:1. Students incur H?W injuries due to the extensive use of computers mandatory for the school's curriculum.
2. Access to computer cannot be reduced.

Conclusion: Teacher monitor the posture while its usage.

Option E:
(E) What proportion of schoolchildren in Harnville already use correct posture while using a computer.
Just think in this way is knowing the percentage or prop of students using the correct posture helps the author to draw the conclusion.
The conclusion is about the reduction in the #of injuries among the students by monitoring the posture, so you need to find a fact/ premise that refers to the the fact that monitoring will help reducing the injuries or not. Its a causal relationship[Monitoring will reduce the # of injuries.]

Prethinking:
do students have access to computer after school hours.
do they going to maintain the same posture while using the PC when they are not in school premises.


In the Answer Options:

B : is a TRAP, its telling opposite to the authors belief. We are concerned about the children who are injured due to the extensive use of computers NOT by the fact that they have inherited or the do by playing games bla bla.... INCORRECT.

C: Is the BEST FIT.

Rest you can eliminate easily.
