Question

Infer: How might the size of a group affect its defense?

Answer 1

More things in a group would equal a bigger and better defense. Meaning that you would have more protection and be able to cover a larger area overall as well.

Answer 2

I don't know exactly what you mean but the size of a group affects its defense because there is a larger group. Therefore, more people would be protecting it, adding more to its defense.
