Final answer:
The answer lies in understanding that gospels are written about their main character, Jesus, by his followers, and not by Jesus himself, which makes option 2 incorrect. Gospels differ from modern biographies by being selective, topical, and focusing heavily on Jesus' death.
Step-by-step explanation:
The option that does NOT represent a difference between gospels and modern biographies is "2) Gospels are written by the main character." Gospels, such as those found in the New Testament of the Christian Bible, record the life of Jesus and are traditionally attributed to his apostles and disciples: Matthew, Mark, Luke, and John. In contrast, modern biographies can be written by either the subjects themselves, if they are autobiographical, or by other authors, if they are standard biographical narratives.
Gospels are indeed selective in the events they cover and often focus heavily on the message and teachings of Jesus, especially on his death and resurrection, which holds a pivotal place in Christian theology. They can be topical, organized around specific themes rather than a chronological account of Jesus' life. This is unlike many modern biographies, which aim to provide a more comprehensive, chronological life account of the subject, including their thoughts, feelings, context, and background information.
