Paraphrasing

1. "The Antarctic is the vast source of cold on our planet, just as the sun is the source of our heat, and it exerts tremendous control on our climate," [Jacques] Cousteau told the camera. "The cold ocean water around Antarctica flows north to mix with warmer water from the tropics, and its upwellings help to cool both the surface water and our atmosphere. Yet the fragility of this regulating system is now threatened by human activity." From "Captain Cousteau," Audubon (May 1990):17.

According to Jacques Cousteau, one of the main sources of cold on the Earth is the Antarctic. As well as the Sun it has a big influence on our climate. The mix of Antarctic and tropical waters keeps the temperature of our planet balanced. However, now this regulating system is in danger due to human activity. ("Captain Cousteau," Audubon (May 1990):17)

2. The twenties were the years when drinking was against the law, and the law was a bad joke because everyone knew of a local bar where liquor could be had. They were the years when organized crime ruled the cities, and the police seemed powerless to do anything against it. Classical music was forgotten while jazz spread throughout the land, and men like Bix Beiderbecke, Louis Armstrong, and Count Basie became the heroes of the young. The flapper was born in the twenties, and with her bobbed hair and short skirts, she symbolized, perhaps more than anyone or anything else, America's break with the past. From Kathleen Yancey, English 102 Supplemental Guide (1989): 25.

According to Kathleen Yancey, the 20s were a turning point in America's history. Firstly, during those years laws were ignored, organized crime was present in the cities, and the police weren't able to stop it. Secondly, jazz music replaced classical music. Thirdly, the 20s might be defined by spread of the flappers with their specific fashion, embodying the separation from American past.
