Answer:
Adolescence
Step-by-step explanation:
Given that infancy, age is the age of little children from the point of birth to about four years
Hence, this cannot be an answer.
Childhood is wrong because the childhood age is the age of 2 to 13. At such a tender age, one cannot go hunting due to fear of wild animals or have the capacity to learn to cook different food
Adult is also not correct because Adult age lies between 21 to 40 when middle age comes by. At this stage, one is expected to have at least basic skills to survive.
Therefore the correct answer is Adolescence. This is the age of 10 to 19. It is the last stage before Adulthood where one has to hone his basic and surviving skills. At this point, it is believed one has full mental capacity.
