This study investigates whether effective question writing reduces the effect of pictures presented with a question. The study contains two measures: In the first measure respondents were randomly assigned to one of nine experimental conditions (3 x 3), thus varying both pictures and verbal instructions. In the second measure verbal instructions were kept identical to wave I, whereas respondents were again randomly assigned to one of three picture-conditions.
