Explanation:

The problem is about conducting a poll accurately and representatively. The first blank should be "population" (defining the group to poll), the second "sample" (constructing a sample), the third "sample" (with points like chosen by chance, representative from subgroups), the fourth "questionnaire" (preparing a valid one, neutral), and the last "results". These concepts relate to survey methodology, which falls under Statistics (Mathematics) as it involves sampling, data collection, and analysis for polls.
