a pro-evolution advocate wants to estimate the percentage of people who favor teaching only evolution in schools. She conducts a nationwide survey of 1980 randomly selected adults 18 years and older. The interviewer asks the respondents, "Do you favor promoting science by teaching only evolution in schools?" Which type of bias is this?
I don't know exactly what types of bias you're choosing from, but in the question, she asks if they promote science by doing this. This implies that if you don't teach only evolution, you aren't promoting science
