A statement that is formulated negatively, easily raises confusion. E.g. “Alcohol commercials shouldn’t be prohibited”. Instead formulate “Alcohol commercials should be prohibited”. The last statement is clearer and therefore easier to answer!
It’s simple, a statement that everyone agrees with, won’t spark a discussion. Try to be on the edge. How about “In Amsterdam all museums should be freely accessible to everyone”?
Prevent misunderstanding and formulate objectively. Words like “often”, “beautiful” or “difficult” are subjective. “The beautiful city of York should be protected from mass tourism”. What is beautiful for you, might be ugly to somebody else. Therefore and in this case, leave out the word “beautiful”.
