Explanation:

Question 1

To answer this, we refer to the text: "A life cycle is the series of stages that all living things experience as they grow up and make new life." Option a is incorrect as it's about daily life, not life cycle stages. Option c is wrong because plants also have life cycles. Option d is incorrect as it only mentions plants, but the definition includes all living things. Option b matches the definition.

From the text: "When the last specimen of a plant or animal completes its life cycle without leaving offspring, we say that species is extinct." Option a (hibernating) is about a seasonal state, not extinction. Option b and d are about life cycle stages, not the end of a species. So option c is correct.

The text states: "Life cycles are different. The differences depend on how long the plant or animal lives and the way they make new life." We extract this information to answer the question.

Answer:

b. the stages all living things pass through
