How is the survival of human kind different from the survival of other animals ?

  • A.The individuals who breed successfully alone contribute to the survival.
  • B.Those individuals who do not reproduce also have a great role to play in the survival.
  • C.Human over-population contributes to survival.
  • D.Specialization of skills and roles has negative effect on survival.

Answer: B

The difference is that individuals who do not reproduce also have a great role in survival.

The passage states that in our society all members contribute to the survival of the species, even if they bear no children, and that those who do not reproduce contribute more at present because of overpopulation.

The other options contradict the passage: breeding alone does not decide survival, overpopulation is called a threat, and specialization is said to increase contributions, not harm them.
