Answer:
1)Gray. The color emphasizes the bleakness of the media room and Mildred's most precious world.
2)Green (or soft green light). The color emphasizes the healthy vibrancy of the natural world. 
Grey color gives the reader a sense of bleakness, solitude, of nothingness. The green color, on the other hand, represents life. All that is natural, the green color of leafs, of trees, etc. The contrast in this two situations affects Montag because he feels bleakness in the media room but he feels the life in the park, in the outside world. 
It could be represented as his personal conflict throughout the book. 
 
        
             
        
        
        
D. Since the father likes taking risks in a game, he might like taking risks in life as well.
This is the best choice. Process of elimination helps when answering this question. From this excerpt, we don't have any clues that the father is possessed or says insane things. We also cannot infer that the woman knitting indicates that the character don't have good clothes to wear. During this time period many women would knit in the evening. We also can't infer that the son is not old enough to play chess. There is nothing to indicate the age of the son or that he doesn't know the rules.
 
        
             
        
        
        
You know it’s a folk tale because we all know that nobody is going to arm wrestle an octopus. It’s just something unrealistic.
