Question

Which statement is correct about the faunas during one of the five major events?

A) The event at the end of the Devonian (Dev.) resulted in an increase in the number of Cambrian faunas.
B) The event at the end of the Cretaceous resulted in an increase in the number of Paleozoic faunas.
C) The event at the end of the Triassic (Tri.) resulted in the extinction of fewer faunas than in any other period.
D) The event at the end of the Cretaceous resulted in the extinction of more faunas than in any other period.

Answer 1

The event at the end of the Cretaceous resulted in the extinction of more faunas than in any other period. The correct option is D) The event at the end of the Cretaceous resulted in the extinction of more faunas than in any other period.

Step-by-step explanation:

The correct statement about the faunas during one of the five major events is option D: The event at the end of the Cretaceous resulted in the extinction of more faunas than in any other period.

The end of the Cretaceous period was marked by a mass extinction event, often referred to as the Cretaceous-Paleogene (K-Pg) extinction event, which resulted in the widespread extinction of many species, including the dinosaurs. This event had a significant impact on the biodiversity of the planet and led to the emergence of new organisms to fill the empty niches left behind.

For example, after the K-Pg extinction event, ferns were more abundant than before, as mentioned in the reference material. However, it is important to note that the statement in option D is the most accurate and directly addresses the question about the number of extinctions. The correct option is D) The event at the end of the Cretaceous resulted in the extinction of more faunas than in any other period.
