11.An overly centralized economy, not the changes in the climate, is responsible for the poor agricultural production in Country X since its new government came to power. Neighboring Country Y has experienced the same climatic conditions, but while agricultural production has been falling in Country X, it has been rising in Country Y.
Which of the following, if true, would most weaken the argument above?
(A) Industrial production also is declining in Country X. (B) Whereas Country Y is landlocked, Country X has a major seaport.
(C) Both Country X and Country Y have been experiencing drought conditions.
(D) The crops that have always been grown in Country X are different from those that have always been grown in Country Y. (E) Country X's new government instituted a centralized economy with the intention of ensuring an equitable distribution of goods.
12.Manager: Accounting and Billing are located right next to each other and the t-wo departments do similar kinds of work; yet expenditures for clerical supplies charged to Billing are much higher. Is Billing wasting supplies? Head of Billing: Not at all.
Which of the following, if true, best supports the position of the Head ofBilling?

(C) The work of Billing now requires a wider variety of clerical supplies than it did in the past.

13.Some anthropologists study modern-day societies of foragers in an effort to learn about our ancient ancestors who were also foragers. A flaw in this strat-egy is that forager societies are extremely varied. Indeed, any forager society with which anthropologists are familiar has had considerable contact with mo-dern nonforager societies.
Which of the following, if true, would most weaken the criticism made above of the anthropologists' strategy?
(A) All forager societies throughout history have had a number of important features in common that are absent from other types of societies.
(B) Most ancient forager societies either dissolved or made a transition to another way of life.
(C) All anthropologists study one kind or another of modern-day society.
(D) Many anthropologists who study modern-day forager societies do not draw inferences about ancient societies on the basis of their studies.
(E) Even those modern-day forager societies that have not had
significant contact with modern societies are importantly different from ancient forager societies.
14.In a study of the effect of color on productivity,50 of 100 factory workers were moved from their drab workroom to a brightly colored workroom.Both these workers and the 50 who remained in the drab workroom increased their prod-uctivity, probably as a result of the interest taken by researchers in the work of both groups during the study.Which of the following, if true, would cast most doubt upon the author's inter-pretation of the study results given above?
(A) The 50 workers moved to the brightly colored room performed precisely the same manufacturing task as the workers who remained in the drab workroom.
(B) The drab workroom was designed to provide adequate space for at most 65 workers.
(C) The 50 workers who moved to the brightly colored workroom were matched as closely as possible in age and level of training to the 50 workers who remained in the drab work-room.
(D) Nearly all the workers in both groups had volunteered to move to the brightly colored workroom.
(E) Many of the workers who moved to the brightly colored
workroom reported that they liked the drab workroom as well as or better than they liked the brightly colored workroom. 15.A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high
immune-system activity. The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.
The researcher's conclusion would be most seriously weakened if it were true that
(A) there was a one-year delay between the completion of a pilot study for the experiment and the initiation of the experiment itself.
(B) people's levels of immune-system activity are not affected by their use of medications.
(C) a few people with high immune-system activity had scores on the test of mental health that were similar to the scores of people who had normal immune-system activity. (D) people who have low immune-system activtiy tend to contract more viral infections than do people with normal or high immune-system activitiy.
