What purpose does paragraph 2 serve in the larger discussion of children’s inability to recall early experiences?

• To argue that theories that are not substantiated by evidence should generally be considered unreliable
• To argue that the hypotheses mentioned in paragraph 2 have been more thoroughly researched than have the theories mentioned later in the passage
• To explain why some theories about infantile amnesia are wrong before presenting ones more likely to be true
• To explain why infantile amnesia is of great interest to researchers

This is a multiple choice.
