a) a fruit diet
b) an insect diet
c) a low inflammatory response
d) inability to mount an immune response

Explanation:

1. Viruses need hosts to survive and replicate, so ideally they do not kill their hosts immediately as it would be counter - productive for their survival.
2. Viruses from bats can cause severe disease in humans because the human immune system over - reacts (goes into overdrive) trying to fight off the novel virus.
3. Bats have a low inflammatory response which allows them to tolerate virus infections better than humans, as their immune system doesn't cause as much self - damage while fighting the virus.

Answer:

1. B. No
2. B. Human immune system goes into an overdrive
3. C. A low inflammatory response
