Final answer:
The subject of this question is Law, specifically the concepts of Tort and Contract. The difference in price mentioned in the question requires further context.
Step-by-step explanation:
The subject of this question is Law. Specifically, the question asks about two legal concepts: Tort and Contract. Tort refers to a civil wrong that causes harm or loss to another person, and it can be used to seek compensation for the wrong done. Contract, on the other hand, refers to a legally binding agreement between parties, which can include provisions for compensation in case of breach.
The difference in price mentioned in the question is not directly related to Tort or Contract. It could refer to a pricing difference in a commercial transaction, but more context would be needed to provide a detailed explanation.
