It is well known that human tears often serve to moisten the eye, protect it from infection, and wash away irritants; such tears are called irritant or reflex tears. Dr. Field hypothesizes that emotional tears have a different biological function. She suggests that by shedding tears when under emotional stress people excrete harmful chemicals that build up in such body fluids as blood serum during emotional stress.

Each of the following, if true, provides some support for Dr. Field's hypothesis EXCEPT:


A) The people most likely to cry when undergoing emotional stress are less likely to suffer from stress-related diseases than is the population at large

B) If a local anesthetic is applied to the surface of the eye, irritant and reflex tears are inhibited, but emotional tears are not

C) The chemical composition of tears that are induced by grit in the eye is identical to the composition of tears induced by emotional stress

D) The concentration of a substance that the body produces only under conditions of emotional stress is thirty times greater in tears than in blood serum

E) Patients who suffer from a condition that prevents secretion of tears display a slower than normal physiological recovery from emotional stress

I think C.
If the emotianal tear and irritant tear have the same composition, then there is no extra harmful-emotional-secretion eliminated.

Conclusion: emotional tears serve to excrete harmful chemicals built up during emotional stres
We want to the statement that does not support this theory.

Each of the following, if true, provides some support for Dr. Field's hypothesis EXCEPT:

A) The people most likely to cry when undergoing emotional stress are less likely to suffer from stress-related diseases than is the population at large
-- This supports the theory that if you cry during emotional stress (thus producing emotional tears), you are less likely to suffer from stress related disease because the tears remove the chemcicals built up by emotional stress

B) If a local anesthetic is applied to the surface of the eye, irritant and reflex tears are inhibited, but emotional tears are not
-- This statement tells us emotional tears can also function as reflex tears. Nothing is said about emotional tears not being able to remove chemicals produced by the body under emotional stress

C) The chemical composition of tears that are induced by grit in the eye is identical to the composition of tears induced by emotional stress
-- Does not support the thoery. Here, it says the composition of reflex tears are the same as emotional tears

D) The concentration of a substance that the body produces only under conditions of emotional stress is thirty times greater in tears than in blood serum
-- Support the theory that emotional tears remove harmful chemicals

E) Patients who suffer from a condition that prevents secretion of tears display a slower than normal physiological recovery from emotional stress
-- Also supports the theory that emotional tears helps to recover one from emotional stress

Choice C for me.

fact- human tears- protect from infection, or irritant

DOCTOR's hypothesis of emotional tears- during emotion stress, people secrete harmful chemicals built in the body fluids to relieve stress

we need to show evidence that more harmful chemicals build up during emotional stress or people get relief from the stress by forming tears



(A) The people most likely to cry when undergoing emotional stress are less likely to suffer from stress-related diseases than is the population at large.- tears help to reduce the stress- evidence
(B) If a local anesthetic is applied to the surface of the eye, irritant and reflex tears are inhibited, but emotional tears are not.- emotional stress is internal
(C) The chemical composition of tears that are induced by grit in the eye is identical to the composition of tears induced by emotional stress.- correct answer- composition of tears has nothing to do with the hypothesis
(D) The concentration of a substance that the body produces only under conditions of emotional stress is thirty times greater in tears than in blood serum.- more stress, more harmful chemical
(E) Patients who suffer from a condition that prevents secretion of tears display a slower than normal physiological recovery from emotional stress.- less secretion of tears less ejection of bad chemical from the body so slow recovery from the stress
