Flint artifacts dating 800,000 to 1,000,000 years ago have been recovered from the Evron Quarry in Israel. Likely created by the hominin Homo erectus, the artifacts have no visual features suggesting that they were exposed to fire, leading some scholars to conclude that these hominins had not acquired control of fire. But Zane Stepka and colleagues recently used a new method to determine whether these artifacts had been exposed to temperatures above 400°C (the typical temperature campfires reach). They concluded that the hominins who inhabited the site may have had control of fire.
Which choice best describes data in the graph that supports the team’s conclusion?
Difficulty: Medium
A:
Artifacts K5_106 and K3_9 were exposed to temperatures above 400°C.
B:
Artifacts L5_239 and K3_18 were exposed to temperatures of approximately 550°C and 650°C, respectively.
C:
All of the artifacts were exposed to temperatures above 100°C.
D:
Artifact K3_9 was exposed to a higher temperature than was artifact K5_106.
