21 balloons is the story of professor william sherman's travels.

in 1883, he set off from san francisco for a balloon ride over the pacific and was found a month later floating with 21 balloons in the atlantic ocean. this seemed an astounding feat and everyone wanted to know what had happened.    

professor sherman was loyal, however, and said he would tell his tale first to the western american explorers club in san francisco, of which he was a member. this built up suspense for several chapters before he began to tell of the wonders of his adventures and the amazing island of krakatoa, an island which had just been blown up by a volcano.  

the residents of krakatoa are all millionaires who live under a "gourmet government" of their own devising. we get to see all the incredible adventures that creative people with unlimited resources would create according to the author.

now lets look at the choices we have

a)students as entrepreneurs

b)courage and determination

c) artificial intelligence

i don't think ai (artificial intelligence) has anything to do with this.

(a) would be wrong because entrepreneurs are people who start their own business.

so it came out to be b i think this is the right answer because you will need courage to make your own stories/skit and you will need determination to keep on going even if you mess up.

the answer would be b.
