Question

Tarshis writes, "Nobody knew what causes polio or how it spread-and there was no cure." This line helps explain why people were particularly scared of polio. Which other line from the story serves a similar purpose?

"If polio attacked teh muscles needed for breathing the disease could be fatal."

"Fortunately, most people suffered only mild symptoms..."

"My grandmother had vivid memories of when polio struck Chester."

Answer 1

It would be sentence A because it explains why it was such a threatening disease

Answer 2

"If polio attacked the muscles needed for breathing the disease could be fatal."

Step-by-step explanation:

This line serves a similar purpose to the first one as it highlights the potential severity of the disease. It suggests that even though most people suffered only mild symptoms, there was a risk of the disease being fatal if it affected the muscles needed for breathing. This would have added to people's fear and concern about the disease.
