Task: Question Answering
Input (English): Passage: Minority leaders may engage in numerous activities to publicize their party's priorities and to criticize the opposition's. For instance, to keep their party colleagues "on message," they insure that partisan colleagues are sent packets of suggested press releases or "talking points" for constituent meetings in their districts; they help to organize "town meetings" in Members' districts around the country to publicize the party's agenda or a specific priority, such as health care or education; they sponsor party "retreats" to discuss issues and assess the party's public image; they create "theme teams" to craft party messages that might be raised during the one-minute, morning hour, or special order period in the House; they conduct surveys of party colleagues to discern their policy preferences; they establish websites that highlight and distribute party images and issues to users; and they organize task forces or issue teams to formulate party programs and to develop strategies for communicating these programs to the public. Question: How do minority leaders gauge party preferences?
Output (English): conduct surveys of party colleagues
