Answer 1

Question 1:
   Answer: b) 5 to 8 million years ago
           A hominid is any member of the biological family Hominidae. These are the "great apes", living and extinct. At present there are humans, chimpanzees, gorillas and orangutans. The word "hominid" has been used in various ways. The original meaning of the taxon Hominidae meant only humans and their closest relatives. Approximately 6-7 mya, the last common ancestor between humans and chimpanzees diverged into at least two separate lineages. Hominins refer to the group of organisms in the lineage that gave rise to humans. So, the possible ans could be "b".

Question 2:
   Answer: lithics
       The Oldowan, sometimes spelled Olduwan, is the earliest widespread stone tool archaeological industry in prehistory. The term "Oldowan" is taken from the site of Olduvai Gorge in Tanzania, where the first Oldowan lithics were discovered by the archaeologist Louis Leakey in the 1930s.
       Lithic fragments, or lithics, are pieces of other rocks that have been eroded down to sand size and now are sand grains in a sedimentary rock
