However / since 有没有较为规律的东西？例如 OG12-34

Which of the following most logically completes the
argument?

Ferber's syndrome, a viral disease that frequently
affects cattle, is transmitted to these animals through
infected feed. Even though chickens commercially
raised for meat are often fed the type of feed
identified as the source.of infection in cattle, Ferber's
syndrome is only rarely observed in chickens. This
fact, however, does not indicate that most chickens
are immune to the virus that causes Ferber's
syndrome, since_____________

(A)chickens and cattle are not the only kinds of
farm animal that are typically fed the type of
feed liable to be contaminated with the virus that
causes Ferber's syndrome

(B)Ferber's syndrome has been found in animals
that have not been fed the type of feed liable to
be contaminated with the virus that can cause
the disease

(C)resistance to some infectious organisms such
as the virus that causes Ferber's syndrome can
be acquired by exposure to a closely related
infectious organism

(D)chickens and cattle take more than a year to
show symptoms of Ferber's syndrome, and
chickens commercially raised for meat, unlike
cattle, are generally brought to market during
the first year of life

(E)the type of feed liable to be infected with the
virus that causes Ferber's syndrome generally
constitutes a larger proportion of the diet

of commercially raised chickens than of
commercially raised cattle

4. GWD21-Q4:

Which of the following most logically completes the passage?

Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed.The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases.A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses.Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.

A.the patients who are correctly diagnosed with this test as not having appendicitis invariably have medical conditions that are much less serious than appendicitis

B.the misdiagnoses produced by this test are always instances of attributing appendicitis to someone who does not, in fact, have it

C.all of the patients who are diagnosed with this test as having appendicitis do, in fact, have appendicitis

D.every patient who is diagnosed with this test as having appendicitis has more than one of the symptoms generally associated with appendicitis

E.the only patients who are misdiagnosed using this test are patients who lack one or more of the symptoms that are generally associated with appendicitis
