T-3-Q13.
The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin. However, since many patients stop taking those drugs within three days, reinfection is common in cases where these drugs are prescribed. A new antibiotic requires only a three-day course of treatment. Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.
Which of the following, if true, most strengthens the argument?
A.Some of people who are allergic to penicillin are likely to be allergic to the new antibiotic.
B.A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.
C.The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.
D.Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections
E.Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.
Why is E...
T-3-Q3.
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?
A.Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed.
B.Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops.
C.Whether for most farms who grow cotton it is their primary crop
D.Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did.
E.Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide.
Why other crops are invovled in the argument, Option B is the answer...
