Final answer:
The subject of this question is Law as it involves concepts like intent, integration, and the interpretation of written agreements. It specifically refers to the parol evidence rule in contract law which restricts the use of extrinsic evidence to contradict the terms of a written agreement. The phrase 'Intent determines integration; 4 corners' highlights the importance of parties' intentions in interpreting the agreement and considering only the written terms within its boundaries.
Step-by-step explanation:
The subject of this question is Law as it involves concepts like intent, integration, and the interpretation of written agreements.
When the phrase 'No extrinsic that contradicts - No prior or contemporaneous - Intent determines integration; 4 corners?' is mentioned, it refers to the parol evidence rule in contract law. This rule states that extrinsic evidence (such as oral statements or prior agreements) cannot be used to contradict the terms of a written agreement.
'Intent determines integration; 4 corners' means that the intent of the parties involved in creating the written agreement is the key factor in interpreting its terms. The agreement is considered to consist of only what is written within its 'four corners' (the four edges of the document).
