I gave my students this multiple choice question: A student is working on a science project display for the school science fair. To best communicate why her conclusions are valid, what should be included on the display?

Only one answer is correct among these 4 choices:
- a list of authoritative sources that supports her conclusion
- instructions for viewers to repeat her procedures
- clearly illustrated diagrams of the scientific principles involved
- a complete write-up of her experimental method and data collected

Could you tell me which one is correct?
