Critical Reasoning

Scientists have several rival theories on the causes of fibromyalgia, a disorder that causes body-wide chronic pain and fatigue. One leading theory holds that conditions such as depression, anxiety, drug use and serotonin deficiency can aggravate or even cause fibromyalgia by interfering with "stage 4," or "deep sleep." This theory is concerned with the function of neuropeptide substance P, which is released in the spinal cord in response to pain and causes nerve endings around the initiating nerves to also become more sensitive to pain. Normally, this mechanism is "reset" during deep sleep. If pain becomes body-wide, however, and the mechanism can not be reset, this process may run out of control.

The theory above on the cause of fibromyalgia rests on which of the following assumptions?

a. The body has a limited amount of control over neuropeptide substance P.
b. Fibromyalgia is a completely preventable disorder, if only other conditions are recognized and treated before it can develop.
c. Deep sleep is necessary to the healthy functioning of the nervous system.
d. The functions of neuropeptides released by the spinal cord must be better understood before a cure for fibromyalgia can be found.
e. Because the causes of fibromyalgia are linked to depression, the disorder should be treated by mental health professionals.

Please explain the solutions too!

I am little confused with options A and C, but IMO, A..below is my reason:

(A) - correct..check the green colored line in the passage
(B) - nowhere in the passasge, the treatment part is considered. Hence, irrelevant
(C) - confused, yet ruling it out as assumption is vaguely connecting fibromyalgia and deep sleep. Option A sounds better..
(D) - irrelevant, same because of option B
(E) - irrelevant, we are not talking about treatment.

Wats the OA ??

IMO: B
Whats the OA?

IMO C

Others are either strong or out of scope

Sorry guys, even I don't know the OA, but you can find the related discussion here :

Confusion between A & C.
Expert Comments may help.

Hi,
OA is C. You can find Adam@Knewton's explanation at:
