Swing voters are people who have not made up their minds at the start of the campaign.
Explanation:
A swing vote is that which is not decided and could go, in fact, in various ways and pick one among many candidates (if there are many) or one between two. This type of voter is not affiliated with any particular political party. They could vote for Trump or Bernie Sanders, or could not vote at all. This is a percent of voters that can't be really accounted for as there aren't many ways to catalogue them or to really influence them.
The problem of waste can be tackled in many ways, such as:
producing less waste (the most important way of reducing waste)
reusing the objects rather than throwing them away after one use
recycling the objects that have to be thrown away
so all the options are correct - all of the above!
