原文:
The Food and Drug Administration has recently proposed severe restrictions on
the use of antibiotics to promote the health and growth of meat animals.
Medications added to feeds kill many microorganisms but also encourage the
appearance of bacterial strains that are resistant to anti-infective drugs.
Already, for example, penicillin and the tetracvlines are not as effective
therapeutically as they once were. The drug resistance is chiefly conferred
by tiny circlets of genes, called plasmids, that can be exchanged between
different strains and even different species of bacteria. Plasmids are also
one of the two kinds of vehicles (the other being viruses) that molecular
biologists depend on when performing gene transplant experiments. Even
present guidelines forbid the laboratory use of plasmids bearing genes for
resistance to antibiotics. Yet, while congressional debate rages over whether
or not to toughen these restrictions on scientists in their
laboratories,little congressional attention has been focused on an
ill-advised agricultural practice that produces known deleterious effects.

問題:
In the passage, the author is primarily concerned with?

(A)discovering methods of eliminating harmful microorganisms without
subsequently generating drug-resistant bacterial

(B)explaining reasons for congressional inaction on the regulation of gene
transplant experiments

(C)describing a problematic agricultural practice and its serious genetic
consequences

(D)verifying the therapeutic ineffectiveness of anti-infective drugs

(E)evaluating recently proposed restrictions intended to promote the growth of
meat animals







正確解答C

我的問題是...文章內容不是在討論餵食食用動物的飼料所參雜的藥品衍生的生化議題嗎?

為什麼答案會變成agricultural practice?

感謝
