People tend to evaluate certain dialects as less sophisticated or as more prestigious. in contrast anthropological linguists view all dialects as equally logical and effective means of communication, and they do not rank speech patterns as better or worse. this approach to the study of language by anthropological linguists is known as

linguistic relativity

Explanation:

Linguistic relativity involves regarding all dialects as equally logical and effective means of communications, and it also avoids to classify speech patterns  within a grading system. Therefore, according to the Sapir-Whorf hypothesis, language influences the thoughts and judgements of their speakers. As a result, no dialect is better than another - each dialect leads to its speakers to have different viewpoints and jump to different conclusions.

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.
