Final answer:
The author shows support for Levi's cooking through the family's actions, such as eating his creations, not complaining about experimentation, letting him cook often, and supporting his professional growth.
Step-by-step explanation:
The author of the passage demonstrates that Levi's family is supportive of his interest in cooking primarily through their actions and responses to Levi's culinary endeavors. While the details within the passages provided do not directly match any of the answer choices, one can infer that, generally, a supportive family would show encouragement through various means such as willingness to try his cooking (eat his various concoctions), offering patience and constructive feedback (not complaining when he experiments with recipes), permitting him to practice his craft frequently (allowing him to cook dinner almost every night), and endorsing his growth and development within the field (audition for the internship).
