Jordan and Marvin’s mother has decided that they will become a lawyer when they grow up, but they seem more artistically inclined. No error

Reading, writing, and arithmetic are essential skill to learn in elementary school. No error
There is a discrepancy in the agreement of nouns in this sentence. "Reading, writing and arithmetic" require the plural form of "skill," "skills." Multiple subjects require a plural predicate to match their form. "Reading, writing, and arithmetic" are not being discussed as a unified group (which is an exception requiring a singular predicate), so the agreement must be plural, because several subjects are being discussed.
