Question

select the correct answer.
what is true about the current extinction rate?
a. it’s slower than the earlier mass extinction rate.
b. it’s primarily attributed to human intervention.
c. it’s attributed to natural environmental changes.
d. it’s necessary for evolution.
e. it’s affecting few species.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: The current extinction rate is faster than earlier mass extinction rates, so A is incorrect.
• Option B: Human activities (e.g., habitat destruction, climate change) are the primary drivers of the current high extinction rate, making B correct.
• Option C: Current extinction is mainly human - caused, not natural environmental changes, so C is incorrect.
• Option D: The current rapid extinction rate is not necessary for evolution and is a threat to biodiversity, so D is incorrect.
• Option E: The current extinction rate is affecting many species (a mass extinction event is underway), so E is incorrect.

Answer:

B. It’s primarily attributed to human intervention.
