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

D.

B is incorrect because we dont care if other remedies when taken orally "can reduce the duration of a cold", this last part is irrelevant.

D gives an alternative explanation to why the zinc treatment could differ when taking orally or through the nose. Says that something in either the oral or nose treatment interferes with the way zinc acts.

My pick is D

The argument is :"the greater effectiveness of the gel must be
due to the fact that cold viruses tend to concentrate in the nose, not the mouth".

Therefore, knowing "Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc" will be helpful in evaluating the validity of the argument (because if the zinc gel contains ingredients that have an impact on the activity of the zinc, then the greater effectiveness is not due to the fact that cold viruses concentrate in the nose).

What the stem leaves us wondering about is whether thereÂ´s something more in the gel or the lozenges that could help in the relative effectiveness of the latter over the former. If their effect is similar, then one has more certainty that cold viruses indeed concentrate on the nose rather than on the mouth.

Responding to a pm:

The argument compares zinc lozenges with zinc gel.
The conclusion of the argument is "the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouth."

Now, we would like to further evaluate the argument i.e. if we need to evaluate the conclusion of the argument, which of the following would help us? Mind you, you want to evaluate the accuracy of the conclusion so you need an option which talks about zinc lozenges vs zinc gel. Only option (D) does this. It asks us to consider whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc. It asks us to consider whether there is another reason for the greater effectiveness of the gel - does the gel have another ingredient which makes the zinc more active/effective and which is not there in the lozenges.
None of the other options talk about gel vs lozenges.

causal passage, we need to make sure there is no alternate cause

same zinc in both the cases either through oral or nasal, but it is more effective in case of nasal

author concludes that nasal one is more effective because of the virus concentration at the nose ( so no other factor or alternate cause apart from the concentration of the virus)

so missing assumption- is there is no other substances either in the oral one ( like some orange or choclate flavor) to make the oral experience less painful and because of it might be possible that this foreign substances reduces the effectiveness of the zinc, so we need to protect with this conclusion with alernate cause- our evaluation question will be around this missing assumption
