Q1 - Though sucking zinc lozenges has been promoted as a treatment for the common cold,
research has revealed no consistent effect. Recently, however, a zinc gel applied nasally
has been shown to greatly reduce the duration of colds. Since the gel contains zinc in the
same form and concentration as the lozenges, the greater effectiveness of the gel must be
due to the fact that cold viruses tend to concentrate in the nose, not the mouth.

In order to evaluate the argument, it would be most helpful to determine which of the following?

A. Whether zinc is effective only against colds, or also has an effect on other virally
caused diseases
B. Whether there are remedies that do not contain zinc but that, when taken orally,
can reduce the duration of colds
C. Whether people who frequently catch colds have a zinc deficiency
D. Whether either the zinc gel or the lozenges contain ingredients that have an
impact on the activity of the zinc
E. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on
their duration

-----------------------------------------------------------

Q2 - Astronomer: Observations of the Shoemaker-Levi comet on its collision course with
Jupiter showed that the comet broke into fragments before entering Jupiter’s atmospherein 1994, but they did not show how big those fragments were. Nevertheless, some
indication of their size can be inferred from spectrographic analyses of Jupiter’s outer
atmosphere. After the fragments’ entry, these analyses revealed unprecedented
traces of sulfur.
The fragments themselves almost certainly contained no sulfur, but
astronomers believe that the cloud layer below Jupiter’s outer atmosphere does contain
sulfur. Since sulfur would have seeped into the outer atmosphere if comet fragments
, it is likely that some of the fragments were at least
large enough to have passed through Jupiter’s outer atmosphere without being burned up.
In the astronomer’s argument, the two portions in boldface play which of the following
roles?
A. The first is a claim that the astronomer seeks to show is true; the second
acknowledges a consideration that weighs against the truth of that claim.
B. The first is a claim that the astronomer seeks to show is true; the second provides
evidence in support of the truth of that claim.
C. The first and the second are each considerations advanced in support of the
conclusion of the argument.
D. The first provides evidence in support of the conclusion of the argument; the
second is that conclusion.
E. The first is a circumstance for which the astronomer seeks to provide an
explanation; the second acknowledges a consideration that weighs against the
explanation provided by the astronomer.

E. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on

Gel is more effective than lozenges because of some reason. => is the conclusion.
A,B- out of scope.
C. - Zinc is believed to be remedy for the problem. so this does not effect.
D - If this is yes, it weakens the arguement, If No, it strengthens. => This is the answer
E. Out of scope

For Q2
A and E are out, as the 2nd statement is not against the conclusion.
D is out -as 2nd statement is not a conclusion.
conclusion is =>it is likely that some of the fragments were at least
large enough to have passed through Jupiter’s outer atmosphere without being burned up.

B is out- 1st is not a claim , but a statement which when taken together with 2, strengthen the conclusion.

Thus C
