hi chris,

I am still not convinced with the explanation of (A). It is already mentioned in the text about the symptoms of the disease with enough certainty.because if that would not have been the case then the sentence could be ,
"Symptoms of the disease might be abdominal cramps, bloating, and anemia. "

Doctors always define a disease with few basic symptoms which must be there in the patient to declare that the patient is inflicted with this SPECIAL disease.

need ur help,

You are correct that doctors define a disease with a few basic symptoms, but you are not correct that all must be there to declare that a patient is suffering from that particular disease. A symptom is what is *likely* to be present if the person has the disease; every person does not have to have every symptom in order for the disease to be there.

I just went on the Mayo Clinic website and found the following verbatim information about the common cold (note that the bolding is mine):
"Signs and symptoms of a common cold may include:
Runny or stuffy nose
Itchy or sore throat
Cough
Congestion
Slight body aches or a mild headache
Sneezing
Watery eyes
Low-grade fever
Mild fatigue

So clearly if you have a cold you may have some of those symptoms; you don't have to have all of them.

The takeaway from this problem is to be VERY wary of extreme language on a "draw a conclusion" type of CR problem.

thanks "Jamie" for going that extra mile.
