Question Wording

I think we should exam people's behaviour of political participation and envolvement in media at the same period of time. There might be cases that people who read and watch more political news less than before but participated in the last election. So when we propose the question examining the political participation, we'd better just look at the most recent one. While for question with regard to the exposure to the media, I think people are tend to answer according to their most recent experience.
