The answer to this question would be METHAPHOR.
Studying in a public place like a station or bus is the worst. And studying in a library or home is the best. studying in a bus or station is worst because there are, at most times, noisy people around. The more unnecessary noise the less focused you are. And studying at home or a library is way better. The library is quiet so you wouldn't have to worry about not concentrating; being at home may be better because the familiar surroundings keep you comfortable.

Because polite is an adjective describing the noun "gnome", you don't need the comma between the adjective and noun.
