BOOKMARKED
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

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

Answer: D

due to the fact that cold viruses tend to concentrate in the nose, not the mouth.

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
