【正确答案】 C

【答案解析】[听力原文] 22-25
The state of Kansas is called the "Bread of America." Because it ranks first in wheat growing and flour milling that may have something to do with the fact that the majority of people in the state are engaged in farming. In addition, there are hundreds of cattle farms in western Kansas, some of which cover 50,000 acres. The state is larger than most states, but rather it has a small population.
In pioneer days, many settlers passed through Kansas seeking rich land and gold father west. Looking upon Kansas as a "useless waste of land", they refused to settle there. However, when Kansas joined the Union in 1861 as a free state opposed to slave labor, the population began to increase. Finally, the railroads helped to attract settlers by selling them inexpensive land.

文中明确指出“The majority of people in the state are engaged in farming”，the majority of people=most people；occupation与engaged in对应。

【正确答案】 B

【答案解析】根据“The state is larger than most states, but rather it has a small population”，选项A、C均排除。50000英亩并不是堪萨斯州的整个面积，而是西堪萨斯州的面积，所以D也排除。

【正确答案】 D

【答案解析】文中提到“Looking upon Kansas as a useless waste of land, they refused to settle there”，在早期探索者看来，堪萨斯州是一片无用的废地，与答案“他们认为这片土地没有生产力”相符。

【正确答案】 A

【答案解析】文章提到，自从1861年堪萨斯州作为反对奴隶制度的自由州加入联邦之后，该州的人口开始增加。因此可以推断出是它对奴隶制度所持的态度吸引了大量外来人口，从而使整个州的人口总量增加。
