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':3394875
'passage':Half-mast vs. half-staff. In American English, a flag flown halfway up its flagpole as a symbol of mourning is at half-staff, and a flag flown halfway up a ship’s mast to signal mourning or distress is at half-mast. The distinction does not run deep, though, as the terms are often mixed up, especially in unofficial contexts. Advertisement.
