Answer:
Response bias
Explanation:
Response bias means: anything in a survey that influences responses. In this situation the question is "Do you favor harsher penalties for individuals who sell guns illegally?" The person is asking a very specific question rather than allowing it to be broad. The scenario is that the surveyor wanted tot estimate the percentage of people who favor just stricter gun laws in general and not within the limits of illegally sold guns. If he were to ask "Do you favor stricter penalties for buying/selling guns?" then it would fit the guidelines of the initial estimate. hope this makes sense :)
