Juan easily taught his cat to jump through a hoop for the reward of food, but could not get his cat to fetch a ball and return the ball to him. The cat would chase the ball but use his paws to roll the ball so he could chase the ball again. The reason the cat had difficulties with fetching the ball was because of:
instinctive drift.

Instinctive drift

Explanation:

Instinctive drift is a phenomenon that occurs when an animal reverts back to instinctual behaviour, instead of continuing engaing in learned, or trained behaviour.

In this case, the cat's trained behaviour is being hampered by instinctive drift because while it can easily follow Juan's instructions when jumping a food (aided by the great incentive of getting food), it cannot help chasing the ball more than once, because rolling a ball to catch it is a highly instinctual behaviour that the cat practically cannot control.

answer: cannibalism, the capac raymi, capacocha, the eight day feast, the combing of the hair

explanation:

the incas have many rituals, cannibalism was always a very ritual thing, which was normally tied to sacrifices, warfare, death, and regeneration.

  the capac raymi was one of the most important ceremonies. it occurred around the summer solstice and was when they worshiped their sun god, also known as inti.

  the capacocho was another one of their most important ceremonies. it was when many children where selected to start their training, and these children where destined to become sacrificial blessings to their sun god, inti. being chosen for this ritual was a blessing.

  the eight day feast was a feast that lasted 8 days and, each day, the day began with a chanting at dawn. a follow up song at noon. which ended with complete silence at the end of the day. on this day, inca royalty was always dressed in silver and gold laced clothing.

  the combing of the hair was the most important ritual to young girls. this ritual was known as the coming of age ceremony, but only the most beautiful girls where chosen. in this ceremony, the girls chose their new name and where chosen as either brides, or princesses of rulers.

  a) written constitution. also known as magna carta and a necessity of the democracies that form federations to regulate the principles by which the government will be governed, because if they had to act without a body of specific laws would produce confrontations.

b) territorial division. federalism is constituted by the division of powers on the geographical basis of each territory.

c) decentralization. in a federal system there is both a central government and units of government lower than the central one, each making decisions regarding the provision of certain public services in their respective geographical jurisdictions.

d) supreme court of justice. to counteract the rigidity of the written constitution, judicial action is required to interpret said constitution and necessary changes can be made.
