Answer 1

A doctor identifies symptoms of nasal congestion, headache, sore throat, hoarseness, and cough in a patient. The conclusion is that the patient is infected by a pathogen Rhinovirus.

Explanation:

• The symptom set (nasal congestion, headache, sore throat, hoarseness and cough) is typical of the common cold, which is most commonly caused by rhinoviruses.
• Plasmodium causes malaria (fever/chills), Salmonella causes gastrointestinal illness, and adenovirus can cause respiratory disease, but rhinovirus is the usual cause of these upper‑respiratory cold symptoms.
• Viral respiratory infections elicit interferon responses in the host, supporting a viral (not bacterial/protozoan) cause.
