Question

medical mystery
1 in autumn of 1975, two mothers in lyme, connecticut, were desperate for answers that their doctors could not provide. their families and others in the lyme area were suffering from a mysterious illness, with symptoms such as headaches, skin rashes, swollen knees, fever, and fatigue. the women contacted the connecticut state department of health and the yale school of medicine for help. two doctors from yale, allan steere and stephen malawista, began an investigation that would result in a groundbreaking medical discovery.
2 the doctors began by conducting individual examinations of each patient.
based on the text, which two facts led investigators to believe ticks were causing the symptoms?
some patients remembered getting a tick bite.
most patients spent a lot of time outside.
many patients lived near the town center.

Explanation:

To determine the facts leading investigators to believe ticks caused symptoms:

• "Some patients remembered getting a tick bite" directly links patients to tick exposure, a key clue for tick - borne illness.
• "Most patients spent a lot of time outside" is relevant because ticks are more common in outdoor environments, increasing exposure likelihood.
• "Many patients lived near the town center" is irrelevant as town centers have less tick - prone habitats (ticks thrive in natural, outdoor, non - urban areas like forests, grasslands), so this doesn't support tick - related causation.

Answer:

A. Some patients remembered getting a tick bite
B. Most patients spent a lot of time outside
