No one who has a sore throat need consult a doctor, because

yeah, going with D - two conflicting claims.

Option D is correct - the two contradicting claims are:
1. No one who has a sore throat need consult a doctor.
2. It is highly advisable in such cases that sufferers seek medical attention when the first symptoms (sore throat) occur.

At first the author suggests against going to the doctor for sore throat but eventually suggests that one must seek medical help before the condition deteriorates but fails the describe the health issue further so that the patient can differentiate normal infection from the epiglo.....,therfore she is contradicting her own argument.

Hello Expert, could you please explain, why option 'b' is incorrect?

OFFICIAL ANSWER:

The argument states initially that “no one who has a sore throat need consult a doctor.” However, it is then pointed out that “several cases of epiglottitis have occurred” and argued that for this condition, which begins with a sore throat and then deteriorates, it is “highly advisable” for sufferers to seek medical attention before the condition deteriorates, that is, when the symptom is a sore throat. So the author claims both that no one with a sore throat need seek medical attention and that some people with a sore throat do need to seek medical attention, and these claims contradict each other. Therefore, (D) is the credited response.

Response (A) is incorrect because the author does not clearly draw “a general conclusion on the basis of evidence of a particular instance” of anything. Even though a specific disease (epiglottitis) is discussed, no conclusion about diseases, in general, is drawn. And having this disease is discussed in terms of “several cases” and “sometimes,” not in terms of a “particular instance.”

Response (B) is incorrect because the author is not concerned with the causes of sore throats and epiglottitis.

Response (C) is incorrect because the meaning of the medical term “epiglottitis” is specified in the third and fourth sentences of the passage in sufficient detail for purposes of the argument.

Response (E) is incorrect because the evidence given in the third and fourth sentences of the passage is adequate for the conclusion that “it is highly advisable” in cases of epiglottitis “that sufferers seek medical attention when the first symptoms first occur.”

OPTION: D
