19/30
19. Edward Jenner
[D] Edward Jenner | English doctor who noticed milkmaids never got smallpox, injected cow pus into a child, and invented vaccination while horrifying medical ethics boards retrospectively.
20/30
20. Amedeo Avogadro
[B] Amedeo Avogadro | Italian scientist whose number (6.022 x 10²³) is so large that counting to it would take longer than the universe has existed.
