How does the illustration you understand more about the robots that tomotaka creates?

the word that best matches the meaning of the expression "went to the big ocean" is died.

the goldfish died, which is why the father looks at the children mournfully. the "big ocean" is the father's way of saying fish heaven. he could have just said that the goldfish died, but this way, the children imagine the fish in a bigger, better place instead of just picturing a dead fish.

explanation:

the reason that neiterkob's daughter most likely tell the beginnings of the maasai is : to explain the readers the origin of maasai culture

with this explanation, the reader will grasp a better concept about it and not lost in the middle of reading.
