Q21:

Scientists have made genetic modifications to cotton to increase its resistance to insect pests.  According to farmers’ report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not.  Therefore, since the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton farmers economically.

Which of the following would it be most useful to know in order to evaluate the argument?

1. Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed
2. Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops
3. Whether for most farmers who grow cotton it is their primary crop

5. Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide

Q30:

Editorial:

In Ledland, unemployed adults receive government assistance.  To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply.  However, the supplement will not raise any worker’s income above what government assistance would provide if he or she were not gainfully employed.  Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.

Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?

1. The government collects no taxes on assistance it provides to unemployed individuals and their families.
2. Neighboring countries with laws that mandate the minimum wage an employer must pay an employee have higher unemployment rates than Ledland currently has.
3. People who are employed and look for a new job tend to get higher-paying jobs than job seekers who are unemployed.
4. The yearly amount unemployed people receive from government assistance is less than the yearly income that the government defines as the poverty level.
5. People sometimes accept jobs that pay relatively little simply because they enjoy the work.
