One variety of partially biodegradable plastic beverage container is manufactured from small bits of plastic bound together by a degradable bonding agent such as cornstarch. Since only the bonding agent degrades, leaving the small bits of plastic, no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded. Which of the following, if true, most strengthens the argument above?
A. Both partially biodegradable and nonbiodegradable plastic beverage containers can be crushed completely flat by refuse compactors.
B. The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bounding agents.
C. Many consumers are ecology-minded and prefer to buy a product sold in the partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher.
D. The manufacturing process for the partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing process for nonbiodegradable plastic beverage containers.
E. Technologica" problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container.
一位学生在日记里这样写道:“晚上,我们一家来到海边游玩,海风吹拂着我的脸,特别舒服”。你对这句话的理解是()。
A. 正确。夜间,陆地温度高,海面温度低;陆地上方空气压强小,海面上方压强大;风从海面吹向陆地
B. 正确。夜间,陆地温度低,海面温度高;陆地上方空气压强大,海面上方压强小:风从海面吹向陆地
C. 错误。夜间,陆地温度低,海面温度高;陆地上方空气压强大,海面上方压强小;风从陆地吹向海面
D. 错误。夜间,陆地温度高,海面温度低;陆地上方空气压强小,海面上方压强大:风从陆地吹向海面
