A student's computational model of a falling object does not account for air flow. Which of the following

statements is true?

This computational model is strong because simplifications can make computational models more
accurate.

This is a simplification, which will create inaccuracies, but computational models of complex systems often
include simplifications.

This computational model must be redone because this simplification will increase the amount of
computational power needed for this program.

This computational model must be redone because computational models should not include
simplifications.
