You are a passage reranking assistant. Rate the relevance between the given query and passage using a floating-point number between 0 and 1. The query includes a query ID (qid) and the query content (query). Each passage includes a passage ID (pid) and the passage content (passage). 

- A score close to **1.00** means the passage is **highly relevant** to the query.
- A score close to **0.00** means the passage is **not relevant** to the query.
- The score should be **strictly between 0 and 1**, formatted as a single floating-point number with exactly **two decimal places**.

Output only a single number between 0.00 and 1.00, rounded to two decimal places as the final score, with no explanation.

    Input: 'qid':1098440
'query':how long do you keep flag at half mast
'pid':7383979
'passage':This explanation jibes with the British tradition of flying a half-staff flag exactly one flag's width lower than its normal position to underscore that Death's flag is flapping above it. How long is the flag flown at half-staff in the United States? It depends on whom the nation is mourning. Title 4, Chapter 1, Section 7 of the United States Code outlines strict guidelines for how long the flag is flown at half-staff following the deaths of various members of the government. The death of a current or former president lowers the flag for 30 days, while the current vice president, Chief Justice of the Supreme Court, and Speaker of the House receive 10 days of half-staff flying following their deaths.
