Although the story does not refer to a special name, lets see that the place where Santiago goes fishing is the Caribbean Sea, in a town near Havana Cuba. The hut of Santiago always had proximity to the sea, due to its fishing activity it is perceived that it lived very close to the sea.
Subject and Verb do not agree. Sequoia and Charles plan to exercise together.
The subject of this sentence is a compound subject (Sequoia and Charles). A compound subject is a plural subject because it has more than one. The verb "plans" agrees with a singular subject because it ends with /s/. In order to make the subject and verb agree, the /s/ at the end of "plans" needs to be eliminated. The revised sentence should be "Sequoia and Charles plan to exercise together."
