Question 116
Medical researcher: As expected, records covering the last four years of ten major hospitals indicate that babies born prematurely were more likely to have low birth weights and to suffer from health problems than were babies not born prematurely. These records also indicate that mothers who had received adequate prenatal care were less likely to have low birth weight babies than were mothers who had received inadequate prenatal care. Adequate prenatal care, therefore, significantly decreases the risk of low birth weight babies. Which one of the following, if true, most weakens the medical researcher's argument?
The hospital records indicate that many babies that are born with normal birth weights are born to mothers who had inadequate prenatal care.
Mothers giving birth prematurely are routinely classified by hospitals as having received inadequate prenatal care when the record of that care is not available.
The hospital records indicate that low birth weight babies were routinely classified as having been born prematurely.
Some babies not born prematurely, whose mothers received adequate prenatal care, have low birth weights.
Women who receive adequate prenatal care are less likely to give birth prematurely than are women who do not receive adequate prenatal care.
Question 117
Formal performance evaluations in the professional world are conducted using realistic situations. Physicians are allowed to consult medical texts freely, attorneys may refer to law books and case records, and physicists and engineers have their manuals at hand for ready reference. Students, then, should likewise have access to their textbooks whenever they take examinations. The reasoning in the argument is questionable because the argument
cites examples that are insufficient to support the generalization that performance evaluations in the professional world are conducted in realistic situations
fails to consider the possibility that adopting its recommendation will not significantly increase most students' test scores
neglects to take into account the fact that professionals were once students who also did not have access to textbooks during examinations
neglects to take into account the fact that, unlike students, professionals have devoted many years of study to one subject
fails to consider the possibility that the purposes of evaluation in the professional world and in school situations are quite dissimilar
