51. Guitar strings often go “dead”—become less responsive and bright in
tone—after a few weeks of intense use. A researcher whose son is a
classical guitarist hypothesized that dirt and oil, rather than changes
in the material properties of the string, were responsible.

Which of the following investigations is most likely to yield
significant information that would help to evaluate the researcher’s
hypothesis?

(A) Determining if a metal alloy is used to make the strings used by classical guitarists

(B) Determining whether classical guitarists make their strings go dead faster than do folk guitarists

(C) Determining whether identical lengths of string, of the same gauge, go dead at different rates when strung

on various brands of guitars.

(D) Determining whether a dead string and a new string produce different qualities of sound

(E) Determining whether smearing various substances on new guitar strings causes them to go dead

Q1.这句解释如何理解?

Information about the strings’ material (choice A) will need considerable supplementation before its

bearing on the hypothesis is clear

Q2另钻个SC牛角尖:

A 处为何与其他选项不同用if而不用wether
