问题 What scientists Johan Feenstra and Rob Hayes did was that
Guofu Zhou would probably agree that

选项 A、adding a color filter will be a simple solution.
B、colored ink remains a tough problem.
C、e-paper will be adopted both in the office and at home.
D、the obstacle now is the user-unfriendly screens.

答案C

解析 推理判断题。由题干中的Guofu Zhou定位至第四段第二句,指出周国富认为装有彩色墨水的阅读器在七年之内会投放市场。接着提到:他现在致力于研究能够显示16级或更多灰色色级的电子纸,它将被用在医学成像上或者做家庭黑白摄影照片的像纸。可见Guofu Zhou认为电子纸张可以办公用,也可以家用。该段第二句提到:一个选择是增加简单的色彩过滤器,但那会阻挡三分之二的光,可见这不是一个好的解决方案;第三句中的colored ink can be ready for the market within seven years与"彩色墨水存在大问题"矛盾,排除。"the obstacle now is the user-unfriendly screens"为第三段第二句的细节,该内容与周国富的观点无关。
