Cognitive Research Trust (CoRT) by Edward de Bono helps us to focus attention directly on different aspects of thinking and to crystallize these aspects into definite concepts and tools that can be used deliberately. One of the CoRT tools suggested is PMI (Plus, Minus, Interesting). Using this tool, examine the following statement:

Which is gerrymandering a problem for the house of representatives but not the senate? a.) members of the house are greatly influenced by their political parties. b.) senators serve longer terms than members of the house. c.) members of the house are more influenced by changes in public opinion. d.) senators are elected in statewide elections rather than in specific districts.
