Answer:
3. Matthew--Jews, Mark--world, Luke--Gentiles
Step-by-step explanation:
The Gospel of Matthew corresponds to Jewish customs and culture and is closely associated with the Jewish people, so we can conclude that the target audience of the Gospel of Matthew was the Jews. This book focuses on the life of Jesus fulfilling Jewish prophecy and its relationship to Judaism and all that is related to it.
It is not known if Luke was a Jew or a Gentile, but it is known that he lived in Syria's Antioch, and is commonly identified as a Gentile. The book written by him (the gospel of Luke) is often related to a book that aimed to present the works of Christ to the Gentiles. The Gospel of Luke presents Jesus not only as God's promised Messiah to the people of Israel, but as Savior of Humanity. He tells us about Jesus' parents, tells us about the birth of his cousin John the Baptist, and focuses primarily on the miracles and holiness that Jesus exercised.
The Gospel of Mark is curiously the oldest and shortest of all gospels, and over sixteen chapters we can identify that it was probably written before the destruction of the Jerusalem temple around 70 AD. Mark's gospel focused on proclaiming the good news about Jesus Christ, emphasizing his constant acting and authority throughout the earth, Mark is believed to have targeted all the people of the world.
