Useful protein drugs, such as insulin, must still be administered by the cumbersome procedure of injection under the skin. If proteins are taken orally, they are digested and cannot reach their target cells. Certain nonprotein drugs, however, contain chemical bonds that are not broken down by the digestive system. They can, thus, be taken orally. The statements above most strongly support a claim that a research procedure that successfully accomplishes which of the following would be beneficial to users of protein drugs?

A．Coating insulin with compounds that are broken down by target cells, but whose chemical bonds are resistant to digestion.

B．Converting into protein compounds, by procedures that work in the laboratory, the nonprotein drugs that resist digestion.

C．Removing permanently from the digestive system any substances that digest proteins.

D．Determining, in a systematic way, what enzymes and bacteria are present in the normal digestive system and whether they tend to be broken down within the body.

E．Determining the amount of time each nonprotein drug takes to reach its target cells.

There is a great deal of geographical variation in the frequency of many surgical procedures—up to tenfold variation per hundred thousand between different areas in the numbers of hysterectomies, prostatectomies, and tonsillectomies. To support a conclusion that much of the variation is due to unnecessary surgical procedures, it would be most important to establish which of the following?

A．A local board of review at each hospital examines the records of every operation to determine whether the surgical procedure was necessary.

B．The variation is unrelated to factors(other than the surgical procedures themselves)that influence the incidence of diseases for which surgery might be considered.

C．There are several categories of surgical procedure(other than hysterectomies, prostatectomies, and tonsillectomies)that are often performed unnecessarily.

D．For certain surgical procedures, it is difficult to determine after the operation whether the procedures were necessary or whether alternative treatment would have succeeded.

E．With respect to how often they are performed unnecessarily, hysterectomies, prostatectomies, and tonsillectomies are representative of surgical procedures in general.
