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.

the correct option is c) “logical reasons.”

writers should explain their position by writing logical reasons. in order to build effective arguments, clear evidence and logical ideas should be used to support the writers’ position.

counterclaims are used when the writers do not agree with a claim proposed by another author.

fair rebuttals are used by writers when a counterclaim to their position is being presented.
