<span>don't know the answer to that sorry2</span>
The sky is blue because when light from the sun enters our atmosphere, mostly blue light is refracted towards where we can see it, while most other colors are not. It's reflected by the atmosphere more because blue has a shorter wavelength, so it will collide with particles more often.
Happy to help :)
He's sailing to Rio De Janiero in Brazil
Montag gets on the subway and starts reading the Bible, because he wants to memorize some lines from it. However, he is being constantly distracted and interrupted by an advertisement for Denham's Dentrifice toothpaste, as its jingle is played over and over again on the subway. He gets really mad because of it and starts screaming and yelling, before he leaves at the next stop.
