Answer 1

Answer:

Ralph body is addicted (negatively resisted) to high Caffeine consumption

This makes the bacterias/ germs - earlier so responsive to antibiotics, resistant to them. So, effectiveness of antibiotics fall.

Ralph case is very similar to above examples. His caffeine consumption has increased so much that his body has been accustomed to excessive caffeine consumption, & hence the effectiveness of more caffeine (in terms of buzz) has reduced.
