The following headline is simple: poll: transit tax supported 3 to 1 . its meaning can be changed in context by adding a subheading: poll: transit tax supported 3 to 1-- large leads have disappeared before now you try it. use the simple statement below or make up your own statement. add another statement so that the context changes the meaning of the first statement. what a great day!
