What can be a hypothesis for this scenario? !

I hypothesize that if I were to present 4 options of mashed potatoe colors (red, green, yellow and blue) to 100 students blue would be the most selected color.

compost can be added to topsoil as a:

pesticide

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
