Looking for answers to question 3.1-3.5.. Thanks!

Now, imagine that as mayor you would like to provide the level of clean air that your citizens prefer. You offer three policies with differing levels of air quality resulting from the policy (high, medium, low). Your city has three equal-sized groups of people, with preferences found in the table below: 3.1. Which citizens have single-peaked preferences? 3.2. Which citizens have multi-peaked preferences? 3.3. Which policy wins if using majority voting? Why? 3.4. Does the median voter theorem hold in this instance? Why or why not? 3.5. Other than majority voting, what type of system could be established to aggregate individual preferences and arrive at a policy decision? Qo-to2iJP20zeiderti
