Answer: Authoritative style of child rearing
Explanation: Also known as authoritative parenting, it is a pattern of parenting that is characterized by high demand and high responsiveness. This results in children showing a wide range of attributes including independence, academic success, social, well-behaved and self-reliant. The child's parents are quite responsive to his/her needs while being firm in setting boundaries.
So if Blake is self-reliant, independent and challenges thought, then he was brought up authoritatively.
