B. He never comes to school
Both conflicts are related to confusion over Gogol’s two names.
In the first excerpt it is about how Gogol has two names, Nikhil and Gogol. Gogol is a pet name used by his family while Nikhil is his "good name". Nikhil is his more formal name and should be the one used at school. However, since Gogol was put on his birth certificate, the school must register him using his legal name.
I agree with the sentence because every opportunity you have in life, every moment, you have a chance to pick what is right instead of wrong.
Answer: Hyperbole
A hyperbole is an exaggeration that is not meant to be taken literally. It is usually used to make a persuasive point or to add emphasis. In this case, "opening a door to eternal tyranny" is an example of an exaggeration of this type. While it is likely that tyranny will not be eternal (the country itself will not be eternal), its purpose is to emphasize the risk of keeping the seat of governent vacant.
