Final answer:
The excerpts suggest that Ichabod Crane may be considered inferior to Brom Bones in cunning and social tactics rather than in academic learning.
Step-by-step explanation:
The person Ichabod Crane is considered inferior to in learning, based on the provided excerpts, is likely Brom Bones. This conclusion can be drawn from the competitive dynamics and rivalry depicted over Katrina's affections and the practical jokes that Brom plays on Ichabod. Additionally, Brom's laughter and possible involvement with the 'pumpkin' incident suggest that he is the only character who is demonstrated to best Ichabod, not in learning, but in cunning and social tactics. The excerpts do not provide enough information to definitively conclude that Ichabod feels academically inferior to any of the characters mentioned in the options.
