Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
I’d say C.
A doesn’t make sense, they definitely could’ve domesticated animals in that time.
B doesn’t make sense either, they could’ve easily seen smoke signals, the sky wasn’t filled with them often.
C is just a weird answer. I doubt they were “passive observers” but probably the best answer to the question.
D doesn’t add up because they definitely needed agriculture/food surpluses. They were always hunting, they obviously ran out of food rather quickly.
So C is the answer.

B) 12.5
Interquartile range, part of the descriptive statistics is where you measure the between the difference of Q1 and Q3. Q2 is then the interquartile range. Further, interquartile range is the midpoint or the mid-spread of the data given.
