Translate the following underlined sentences into Chinese.Competition protects the freedom of the individual by ensuring that there is no monopoly of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly.
【正确答案】：
竞争可以确保没有权力垄断，从而保障个人的自由。 
【题目解析】：本题考查语序的调整。句尾的by ensuring是状语，表示“通过某种方式”，翻译成汉语时放在句尾比较怪异，所以可以变为句子主干，然后把原本的主干放在后边，用一个表示因果关系的连词连接即可。competition：竞争； individual：个人；ensure：确保，保证；monopoly：垄断。
