Which diagram shows an example of refraction?

I predict that the potato  in the lowest sugar solution

(water) will gain the most mass through osmosis, whereas the 80% sugar

concentration will lose the most mass through osmosis. I predict this

because I think that the potato chips will try to gain and lose water

between the two sides of its cell wall in order to reach an

equilibrium between them because the 80% sugar solution has a high

amount of sugar molecules, which can not diffuse through the membrane,

I think that the potato will lose water in order to make the solution

on the outside of its membrane equal to the water concentration on the

inside thus losing mass. I also predict that the other

concentrations (60%, 40%, and 20%) will lose mass, but in lower

numbers compared to the 80% sugar solution (the lower the

concentration, the higher the mass). However, since the distilled

water carries no sugar molecules, I think that the potato chip will

gain water to create a balance between the two sides of the cell wall,

making it gain mass.
