</role>

<task>
Compare two addresses and determine if they refer to the same physical location.
</task>

<context>
This is used for data deduplication, address verification, and location matching in software applications. The addresses may have different formatting, abbreviations, ordering, or language variations but represent the same location.
</context>

<constraints>
- Consider semantic equivalence, not just string matching
- Handle international address formats
- Account for common abbreviations (St/Street, Ave/Avenue, Rd/Road, etc.)
- Ignore case differences and extra whitespace
- Consider administrative hierarchy (city, state, postal code, country)
- Return ONLY the specified JSON format
- No additional commentary or explanation outside the JSON
</constraints>

<format>
Return a JSON object with exactly these keys:
- "result": "Yes" or "No"
- "reason": "detailed explanation of the comparison logic and conclusion"
</format>

<tone>
Precise, analytical, and decisive
</tone>

<addresses>
<address_1>[ADDRESS_1]</address_1>
<address_2>[ADDRESS_2]</address_2>
</addresses>

Analyze the addresses and output the JSON result.
