Option 1: Narrow -> This is a synonym of parochial, not an antonym, as both mean limited in scope or outlook.
Option 2: Illiterate -> This refers to lack of reading/writing ability or education, which is unrelated to the meaning of parochial (narrow-minded or limited in scope).
Option 3: Erudite -> This means learned or knowledgeable, but doesn't directly oppose the "narrow scope" meaning of parochial.
Option 4: Global -> This means worldwide or comprehensive in scope, which is the direct opposite of parochial (narrow, limited perspective).
Hence, Option 4: Global -> Parochial means having a narrow or limited outlook, while global means having a broad, worldwide perspective, making them perfect antonyms -> correct
