我觉得从这两个方面都可以加以削弱
OG11-16. In Swartkans territory, archaeologists discovered charred bone fragments dating back one million years.

Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?
