This is typical of political surveys and other surveys where there is a "preferrable" outcome, but I don't think in this case they are trying to get a specific outcome. Maybe feedback can make subsequent surveys better and reduce the ambiguity of results.
It's typical of all surveys. You either need to go into extensive detail to remove the ambiguity of the questions, or you need to allow people to state what they think in plain language. Taking surveys to gather information is like using record sales to measure what kind of music is best; there are a billion confounding factors and none of them are covered by the abjectly simple metric used.
