Final answer:
In 'My Ántonia,' the narrator suffers from quinsy, an inflammation of the tonsils, which is a type of peritonsillar abscess.
Step-by-step explanation:
In the novel My Ántonia, the narrator gets quinsy, which is an inflammation of the tonsils. Quinsy is a term that refers to a peritonsillar abscess, which is a complication of tonsillitis. It is a condition that affects the area around the tonsils, and it is usually characterized by a collection of pus beside the tonsils that can cause severe throat pain, fever, and difficulty swallowing.
The tonsils are part of the lymphatic system, which is critical for your body's defense mechanisms against infections. While the other options listed, such as Peyer's patches, bronchus-associated lymphoid tissue, and mucosa-associated lymphoid tissue, are also related to the lymphatic system, they are not affected by quinsy.
