Give some examples of how Margot is bullied by her classmates.
They put her in a closet and left her in there. She didn’t get to see the sun because she was still locked up in there

The children locked up Margot in the closet and enjoyed the sun. They deprived her of the same experience and was let go only after the rains came back.

Explanation:

Ray Bradbury's All Summer In A Day is about how children in an elementary school in Venus experience the sun. The character of Margot is the protagonist, and she ends up being bullied because she was different, and had come from the earth.

The children in the school began to oppose whatever Margot say about the sun. Since she was different from them, they do not believe what she said. She was treated differently by them, owing to the fact that she had come just some 5 years back to Venus while they were born in the planet. They cornered her while the teacher was away, and put her in a "closet, where they slammed and locked the door". Then they enjoyed the sun while she was still locked up in the closet, thus, depriving her of the experience.  

the answer would be: it explains that at least one son must join the church

the expression ''as the tithe of his sons'' indicates how his father intended for at least one of his sons to serve the church. this phrase demonstrates that his father offered him as a last resort since none of his brothers chose to serve the church.

hope this answer you: )!
