Question 5

Match between columns
                        Premises: Animals that have too few offspring risk that all of them will be lost to predators, and therefore, their genes will not be passed onto the next generation. Animals with too many offspring may not be able to take care of all of them. Therefore, most animals have an intermediate number of offspring.
