The answer to this was no-where in the books. I had done basically every single B1 question as preparation, and I recalled in one of the questions it mentioned briefly that sickle-cell carriers have more resistance to malaria than normal people.

Only me and an African boy who already had malaria got the answer to this in my year :P.
