Are you looking for projects like experiments?
A person should eat energy bars and they should eat energy drinks because it supplies a good amount of carbohydrates (sugar) that can quickly convert inside your body to energy.
(Some good examples of energy drinks would be the brand 'Gatorade')
I am not so sure what exact brand of energy bars to eat, but I know for a fact that each energy bar contains carbohydrates, so probably any energy bar would work. :)

The answer to 2-7 would be -5, but 7-2 would be 5, depends how specific one is trying to be.
If we talk about mathematics and the science behind geography, east and west are directions that may represent infinitely. The reason why quantity exist is to measure and create scales on how far an object is from the origin or the point of locus.
These directions can be compared to a line in math which is an endless and limitless progress of points connected without a direction however, incorporating a specific direction could still represent a endless point of west; an endless point to east. Conclusively both are infinite and long unless determined and specified by a continouous measure.
