Question: How does this information explain the likelihood of a more violent response in someone who has already had food poisoning caused by salmonella bacteria?

a. The likelihood of them having a more violent response is lower since the body knows to produce more antibodies to fight the bacteria.

b. White blood cells ingest bacteria, which means that the white blood cells will turn into an infection. Since there are more red blood cells than white blood cells and they aren't even, it's going to take your body a much longer time to recover then if the red and white blood cells were equal

c. A more violent reaction to salmonella is likely because the body is now familiar with the antigen on the salmonella. As a result, more antibodies can be produced in a shorter amount of time. This can augment symptoms such as fever and vomiting.

d. The body will become familiar with the salmonella bacteria and build up an immunity to it.
