H. ergaster could have been the first to a. use and control fire. b. migrate out of Africa c. make tools. d. Both a and b are correct. e. a, b, and care correct.

Short Answer

Expert verified
d. Both a and b are correct.

Step by step solution

01

Evaluating Option A

H. ergaster is indeed believed by some scientists to have been one of the first hominids to use and control fire. This makes option A a plausible answer.
02

Evaluating Option B

H. ergaster has been found in African as well as Eurasian fossil records, which suggests that they were among the first hominids to migrate out of Africa. Hence, option B is also a plausible answer.
03

Evaluating Option C

H. ergaster did use tools, but they were not the first hominids to do so. Tool-making has been attributed to earlier hominids, such as Homo habilis. Therefore, option C is not a correct answer.
04

Evaluating Option D

Option D states that both A and B are correct. Since we have established that both A and B are plausible answers, option D is indeed a correct answer.
05

Evaluating Option E

Option E claims that all statements, A, B, and C, are correct. However, as we have determined that statement C is not correct, option E cannot be the right answer. Based on this analysis, the correct answer is: d. Both a and b are correct.
