Question

at living things have a beginning and an ending. life begins with birth and ends with death. between life and death, living things grow and mature. for example, tadpoles are born and then grow and change into frogs. before the frogs die, they reproduce and make more tadpoles, which completes the cycle of life. what would happen if no new frogs were born to replace those that died? the answer is simple. there would be no more frogs in the world. they would become extinct. the goal of all living things is to survive. because all living things eventually die, they must reproduce to keep the species alive.
what is the central idea of this paragraph?
○a. reproduction is a necessary part of life.
○b. living things require food to stay alive.
○c. animals become extinct when they die.

Explanation:

The paragraph starts by stating that all living things have a beginning and an end. It uses the example of tadpoles turning into frogs and frogs reproducing to make more tadpoles. Then it poses the question of what would happen if no new frogs were born (they would become extinct). Finally, it concludes that because all living things die, they must reproduce to keep the species alive. So the main idea is about the necessity of reproduction. Option B about food is not mentioned. Option C is incorrect as the paragraph says animals become extinct when there's no reproduction (not just when they die).

Answer:

A. Reproduction is a necessary part of life.
