A. What type of information you are looking for. The rest can be answered when doing the internet search.
The correct answer is that Alex and Joe have C. Contrary views of life.
This is because contrary means opposing, or opposite. Using the metaphor of the cherry, Alex believes that life is a bowl of cherries, meaning that he looks at life in a positive way. To Joe, life is "the pits", which means he is looking at life with a negative view. This shows the opposing, or contrary nature, of their beliefs, which shows you that the answer is C.
Hope this helps!
