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.
为什么选E啊 虽然看了半天觉得应该是E
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?
A.The government collects no taxes on assistance it provides to unemployed individuals and their families.
B.Neighboring countries with laws that mandate the minimum wage an employer must pay an employee have higher unemployment rates than Ledland currently has.
C.People who are employed and look for a new job tend to get higher-paying jobs than job seekers who are unemployed.
D.The yearly amount unemployed people receive from government assistance is less than the yearly income that the government defines as the poverty level.
E.People sometimes accept jobs that pay relatively little simply because they enjoy the work.
Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides.New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt.Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.
In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT:
A.What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides?
B.To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?
C.What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
D.How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?
E.Are the chemical properties that make potassium chloride an effective means for preserving animal hides the same as those that make common salt an effective means for doing so?
