The preposition among takes an object made up of more than two items, while the preposition between takes an object make up of exactly two items.
As and like can both be used to suggest similarity between two words or word groups. However, certain situations require the use of like, and others require the use of as.
Like draws a comparison between two nouns and functions as a preposition meaning “similar to.”
As indicates a similarity between clauses, two phrases containing both a subject and a verb. As also introduces an adjective that is used in a comparison or a noun that indicates status.
The adjective fewer properly modifies nouns that express quantities that can be counted; lessmodifies nouns that express quantities that cannot be counted.
