Coursera is a MOOC platform that has provided free online courses to two million students, and is now looking toward mobile optimization and workforce development.
Not all technology enhances culture in a creative way; technology can also help facilitate political oppression and war via tools such as guns.
选项 A、Technology should be used in a creative way.
B、Technology should be developed because it can enhance culture.
C、Technology is a double-edged sword.
D、Technology should not be developed because it brings about war.
答案 C
解析 原文的意思是“并非所有技术都能创造性地提升文化，技术也可能通过制造枪炮等工具产生政治压迫和战争”，可见讲话人提到了技术的两方面，因此可以被称为“双刃剑”(double-edged sword)，因此选C。
