I DO NOT understand the following! Please HELP :)

1st Part
Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A-, B-, and C- ions, all of which are colorless. When a solution of C is mixed with one containing A- ions, the color changes from red to green.
1) Which species is oxidized?
2) Which is reduced?

2nd Part
When a solution of C is mixed with one containing B- ions, the color remains red.
1) Is C a better oxidzing agent than A?
2) Is C a better oxidizing agent than B?

Part 3
Arrange A, B, and C in order of increasing strengths as oxidizing agegnts.
