Question

Before vaccines, many children suffered from debilitating — and killer —

illnesses such as measles, polio, smallpox, and diphtheria. A simple scratch

could be deadly if it became infected with the bacteria responsible for tetanus

(or “lockjaw”). Vaccines, though, have changed this. Smallpox is completely

gone from the world, and polio nearly so. Outbreaks of measles and diphtheria

are rare, especially in the United States. Tetanus infections continue to decline
worldwide

How does paragraph contribute to the development of ideas in the

passage?

a. It emphasizes the positive impact vaccines have had on people’s

overall health.

c. It reveals that not everyone takes vaccine to protect against these

diseases.

d. It stresses how some diseases continue to persist despite vaccines.​
