the answer to Part A?
A "Before vaccines, many children suffered from
debilitating - and killer - illnesses such as
measles, polio, smallpox and diphtheria."

O B “The body is designed to fight off foreign
invaders, such as germs. To do this, it needs to be
able to distinguish elements of itself from
outside agents (nonself).' (Paragraph 5)
O C "The antibodies 'remember' the germ. This
creates immunity against future infections with
the same type of germ." (Paragraph 12)
