【正确答案】 B

【答案解析】[解析] 逻辑衔接题。本句应为主从复合句，主句提到uncertainty in three areas，即在三个方面存在着不确定性，从句的大意是：人们确实想看移动电视，可以判断主从句有相反的意思，even if表示“即使”，引导让步状语从句，符合句意。避错指导：as if意为“似乎，仿佛”，例：She looked as if she were made of ice．她看起来似乎是冰做的。if only“只要”，如：if only I got invited, I would be glad to go.只要我被邀请，我一定会去。if“如果，倘若”，引导条件状语从句，如：If I were to go，I would be late、倘若我去，就要迟到。
