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

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).

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
Eliminate: Out of scope "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
Same reasoning as A.
C. Whether people who frequently catch colds have a zinc deficiency
Eliminate: We're not talking about the chances of zinc deficiency, the stimulus only talks about zinc being a treatment.
D. Whether either the zinc gel or the lozenges contain ingredients that have an
impact on the activity of the zinc
My choice. Yes, if there is an ingredient that has an effect on the activity of zinc, the conclusion does not follow. We would not know whether the virus lives in the nose or mouth. Inversely, if there is no ingredient in the cold medication that has an impact on zinc then the conclusion would follow.
E. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on
their duration
We're only talking about zinc being able to treat the cold. We're not comparing degrees of treatment.

Answer:


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.

Argument: Zinc performs better when applied nasally than when consumed orally because cold viruses tend to concentrate in the nose.
So the way both medicines perform is same and one is not inherently better than the other medicine? Only concentration of cold viruses makes gel based medicine more effective.


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 OOS

B. Whether there are remedies that do not contain zinc but that, when taken orally,
can reduce the duration of colds OOS

C. Whether people who frequently catch colds have a zinc deficiency Then both medicines will be ineffective. Not helping here. OOS

D. Whether either the zinc gel or the lozenges contain ingredients that have an
impact on the activity of the zincIf yes, then argument fails, else strengthens it

E. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on
their durationAlthough gel has an effect, it doesn't help answer whether zinc gel performs better because of virus concentration in nasal area

D. Whether either the zinc gel or the lozenges contain ingredients that have an

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

Answer:


The answer is D

The composition and concentration of zinc in Zinc gel and lozenges is same but the effect is much more when it is applied nasally .
There must be some other ingredient in Zinc gel to make it much more effective than lozenges.
Option D is saying this

Type - evaluate
Boil it down - 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.

A. Whether zinc is effective only against colds, or also has an effect on other virally caused diseases - Out of scope - other diseases are not relevant

B. Whether there are remedies that do not contain zinc but that, when taken orally, can reduce the duration of colds - Irrelevant - we are not concerned about other remedies

C. Whether people who frequently catch colds have a zinc deficiency - Irrelevant

D. Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc - Correct - if either gel or lozenges contain ingredients that have an impact on the activity of the zinc, then it weakens the claim else it does not

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

Answer D

Background information indicates that nasally applied zinc gel is more effective that sucking zinc lozenges. So the arguments come to the conclusion that the nasally applied version works better because the cold virus is concentrated in the nose.
Approach: We actually need to find an answer choice that helps us to determine the validity of the conclusion.

A. Whether zinc is effective only against colds, or also has an effect on other virally caused diseases
Sorry, effectiveness of the lozenges to other virus is not our concern

B. Whether there are remedies that do not contain zinc but that, when taken orally, can reduce the duration of colds
Duration of cold and other remedies are not our concern.

C. Whether people who frequently catch colds have a zinc deficiency
The claim, "People who catch cold frequently", is narrowing the topic.

D. Whether either the zinc gel or the lozenges contain ingredients that have an impact on the activity of the zinc
If there’s an ingredient in zinc gel/lozenges have an impact on the activity of zinc, it will give us a valid reason to evaluate the conclusion.

E. Whether the zinc gel has an effect on the severity of cold symptoms, as well as on their duration
Same reason as B.
