According to recent research, a blindfolded person whose nostrils have been pinched so that smelling is impossible will have great difficulty in differentiating a bite of an apple from a bite of a raw potato. This clearly demonstrates that taste buds are not the only sense organs involved in determining the taste of a piece of food.

Which of the following premises, is an assumption required by the argument?

a. All people agree that an apple and a potato differ in taste.

b. There are no other senses involved in tasting other than taste, smell, and sight.

c. The word "taste" can be used to describe an experience that involves sight or smell or both.

d. The research was based on experiments that were conducted on a broad spectrum of the general population.

e. People who have been blindfolded and whose nostrils are pinched can differentiate a bite of an apple from a bite of an onion more easily than they can differentiate a bite of an apple from a bite of a raw potato.

What is the negation of a? Would it be - "No one agrees that an apple and a potato differ in taste" or is the negation - "At least one person doesn't agree that an apple and a potato differ in taste"?
I chose A because I negated it the first way I described above. I am guessing the negation is the 2nd way.

Thanks

This is a Veritas Prep QBnak question.
I went through through through explanation in the Vertias Prep QBank, but still have doubt.


First of all, the negation of (A):

(A) All people agree that an apple and a potato differ in taste.
Negation: Not all people agree that an apple and a potato differ in taste.
This means there is at least one person who does not agree that an apple and a potato differ in taste. It is still possible that taste buds are not the only sense organs involved in determining the taste of a piece of food. Even after we negate (A), the conclusion is possible so (A) is not an assumption.
Think of it this way: The given research was conducted. Blindfolded people with pinched noses found it very hard to differentiate the taste. One person comes up and says that he himself cannot differentiate between the two while looking and smelling. Does it mean that senses other than taste buds are not involved? No. There could be many other people who feel that they can easily differentiate between an apple and a potato taste. So other senses could be involved. So (A) is not your answer.

Let's negate (C)

(C) The word "taste" can be used to describe an experience that involves sight or smell or both.
Negation: The word "taste" can not be used to describe an experience that involves sight or smell or both.
It says that "taste" does not involve sight and smell. But our conclusion is based on the premise that sight and smell are involved. Hence we need (C) to be true to arrive at our conclusion.

Hello,

A can be negated to mean "No one can tell the difference between the taste of apple and potato". This includes people with eyesight etc. Now when one applies this to the first statement, one understands that no one can tell the difference is taste between potato and apple while some blind people can tell the difference, although with a bit of difficulty. All that might let us to conclude is that eyesight might be an obstacle in recognizing or differentiating between the taste of two or more food items. We can in no way conclude that taste buds are not the only receptors of taste.

Hope it is clear. Let me know if you require further explanation.

Negate (B): There ARE other senses involved in tasting other than taste, smell, and sight.

Conclusion of the argument: taste buds are not the only sense organs involved in determining the taste of a piece of food.

Can the conclusion hold even after negating (B)? Sure, even if some other sense are also involved, the conclusion is saying that taste buds are not the only sense organs. So (B) is not the assumption.

All people becomes not all people which does not mean no people. So this assumption on negation does not destroy the argument.

Also C provides a clear explanation as to why the people might consider different things to be of same taste. Because if smelling is helpful for people to distinguish b/w things of same "taste" (Here taste takes other form as mentioned in the definition of taste) then taste buds might not be the only organs to determine the taste of the item.

Can a conclusion also become an assumption?
Based on the experiments I concluded that apart from taste buds, taste involves other senses as well. This then becomes a fact inferred and thus ground for my conclusion. How is this an assumption then? Or maybe I am missing something.

Skin is out of the bounds of the argument isn't it ?

Negate (B): There ARE other senses involved in tasting other than taste, smell, and sight.

Conclusion of the argument: taste buds are not the only sense organs involved in determining the taste of a piece of food.

How would you negate D?

The research wasn't based on experiments that were conducted on a broad spectrum of the general population.

So this would mean that we only took a small spectrum and maybe that affected the results?

Negate D: Research was based on experiments that were not conducted on a broad spectrum of the general population.

The conclusion does not say that for people of most classes/regions, taste buds are not the only sense organs involved in determining the taste of a piece of food.

It is acceptable if the research was conducted on a few people and it was determined that other senses are involved. Even if some people found it difficult to differentiate between the two things, we can say that other senses are involved. They may or may not be involved for all - it doesn't change anything.

Don't know whether it would be stupid question but word order of option C has confused me .


"" The word "taste" can be used to describe an
experience that involves sight or smell or both. """



Here ,is it not possible to assume that " taste can be used to describe an experience that involves sight only or smell only or both ?""

, sight or smell or both ? so Taste can be describe in term of sight only . in this case , don't need more than one organ to experience taste of a food .
