The guppies evolved at a rate between 3700 and 45,000 Darwin's. For comparison, artificial-selection experiments on mice show rates of up to 200,000 Darwin's while most rates measured in the fossil record are only 0.1 to 1.0 Darwin.
Guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in guppies that colonized a high-predation
With each generation, more guppies passed on the gene for small spots to their offspring. The rocks became smaller. More guppies with small spots survived long enough to pass on the gene for small spots to their offspring the rocks became smaller.

Well, carbohydrates burn and release energy. Nucleic acids give identity (like DNA, RNA). Lipids also give energy, but it's more difficult (they must be first turned into carbohydrates first). Proteins are building blocks for the cells.
Now, knowing all of this should make it easy to choose the correct answer :)
