"A cocoon" is thus the correct answer, and the corrected sentence reads, "As part of their development, caterpillars form cocoons and eventually emerge as moths or butterflies."

As with pronouns, when a noun or group of nouns is replaced in a sentence by another noun, they must agree in number. The multiple subjects "Dedication," "work," and "attention" call for a plural word. A simple correction would be "important factors"

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.
