Conclusion Students should have access to their textbooks whenever they take examinations.
Author's line of reasoning Formal performance evaluations in the professional world are conducted using realistic situations. The author provides examples of physician, attorneys and physicists who are allowed to have knowledge materials handy for reference.
Pre-thinking The author assumes that the outcome of performance evaluations and examinations are the same. Hence the author suggests whatever methods are application to performance evaluation should be applicable to examinations as well. What if this is not the case, then the author's argument is questionable.
Answer Choice Elimination(A) cites examples that are insufficient to support the generalization that performance evaluations in the professional world are conducted in realistic situationsOut of Scope - The ask is to find a flaw in the conclusion. This statement does not provide any information to do so.
(B) fails to consider the possibility that adopting its recommendation will not significantly increase most students' test scoresThe goal of the plan is not to improve the test scores. The author proposes that the students should have access to their textbooks whenever they take examinations as the author consider the event similar to performance evaluation in which people are allowed to keep reference materials handy.
(C) neglects to take into account the fact that professionals were once students who also did not have access to textbooks during examinationsThis is not in scope of the argument. The purpose of examination and performance evaluation is different and hence the methods implied in one may not be applicable to another.
(D) neglects to take into account the fact that, unlike students, professionals have devoted many years of study to one subjectThis is not in scope of the argument.
(E) fails to consider the possibility that the purposes of evaluation in the professional world and in school situations are quite dissimilarThis is correct ! The purpose of examination and the purpose of evaluation are quite dissimilar. Hence the two event cannot be compared and should have different criteria for evaluation.
