Given that both silica gel and alumina contain a polar oxygen surface and some hydroxyls:
why do you think that the carotenes move more rapidly with the solvent than the xanthophylls?

I recommand you go to wikipedia and type in the molecular name. Once you get the structure of the molecules, you should be able to answer question 1.
I give you the hint for question 2. The lesser interaction molecule the faster it moves. Both silica gel and alumina are hydrophilic with polar groups.
