选项 A、as if
B、even if
C、if only
D、if

答案B

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。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。
