Question

Quizplus · Accepted Answer

The statement mentions that modern humans and their ancestors lived during a climate anomaly, which implies that the climate during their time was different from what was considered typical or usual.

Answer: B
 The statement suggests that for most of Earth's history, the planet was much cooler than it has been in the last two million years. This is in line with scientific studies that show that Earth has experienced periods of glaciation and warming throughout its history.

Answer: D
 The statement claims that past climate changes have been abrupt, which is supported by studies of the geologic record. Geological evidence shows that the climate has changed rapidly in the past, typically over a period of decades to centuries, rather than over millennia.

Therefore, the best choices are C and D.
