CR WEAKEN- SENSES

[vishalc581]

The five senses have traditionally been viewed as distinct yet complementary. Each sense is thought to have its own range of stimuli that are incapable of stimulating the other senses. However, recent research has discovered that some people taste a banana and claim that they are tasting blue, or see a
color and say that it has a specific smell. This shows that such people, called synesthesiacs, have senses that do not respect the usual boundaries between the five recognized senses.


Which one of the following statements, if true, most
seriously weakens the argument?

(A) Synesthesiacs demonstrate a general,
systematic impairment in their ability to use
and understand words.

(B) Recent evidence strongly suggests that there
are other senses besides sight, touch, smell,
hearing, and taste.

(C) The particular ways in which sensory
experiences overlap in synesthesiacs follow a
definite pattern.

(D) The synesthetic phenomenon has been
described in the legends of various cultures.

(E) Synesthesiacs can be temporarily rid of their
synesthetic experiences by the use of drugs.


Confused between A and B.

I thought B states that there is some other sense that is responsible for the synesthetic experiences.


Can you please explain.

the speaker is concerned only with "boundaries between the five recognized senses". so, any notion related to other senses is irrelevant.
