1)An example of cause and effect is when Mae killed the man in the yellow suit. That was the cause and the effect was that she had to go to jail and had to go to the gallows.
2) Another example is how Winnie decided not to drink the spring water so the effect was that she died and didn't get to be with Jesse.
3) Lastly another example is when Winnie says thinking about the thought of seeing Jesse gives her the flutters. The cause is Jesse and the effect is she feels all fluttery.
