成立: an agreed contract and a story's legendary background
Read the contract concluded after both sides agreed and the old legend forming a story's background, identifying each object of 成立.
Formation of a contract and a story
成立 (せいりつ) means formation or establishment. The contract sentence supplies agreement to terms and a concluded contract; the story sentence supplies background to the story's formation.
Identify what 成立 concerns and the accompanying information. Agreement is stated for the contract, and an old legend for the story's background. No party names or formation dates are supplied.
Agreement and an old legend
「双方が条件に同意し、契約が成立した。」 (The contract was concluded when both sides agreed to the terms.) Both sides agreed to the terms and the contract was actually concluded. Read the stated agreement and result without turning the sentence into legal requirements or advice about a real contract.
「この物語が成立した背景には、古い伝承がある。」 (An old legend forms the background to this story.) The old legend forms the story's background. In the Japanese sentence, the clause この物語が成立した modifies 背景; it adds no separate creator or specific formation date.
Keep the object and its supporting information
契約が成立した concerns a concluded contract, while 物語が成立した背景 concerns the story's formation background. Agreement and background provide different information around the same word.
The supplied English story sentence centers on the old legend as background. Preserve that wording rather than using it to infer who created the story or when it took shape.
What information accompanies 成立 for the contract and the story?
Show the answer and why
The contract sentence gives both sides' agreement to the terms. The story sentence gives an old legend in its background, without added parties, a creator or a formation date.
