Harry walked to the kitchen to make food. His parents died in a “car crash” when he was a baby. He became a waffle. How much sugar is in a waffle?

This depends on his blood to sugar ratio and the variable of the type of transformation process that he used to transform into a waffle. Energy might have been burned in the transformation even if it used an outside power source.

wavelength variability is the right one

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
