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':1099219

'pid':8564791
'passage':Mucinex is the brand name for a drug called guaifenesin. There are no significant drug interactions with guaifenesin. It's ok to give mucinex and ibuprofen together.

A humidifier and steamy showers, warm compresses to the sinuses, and a neti pot (if he's old enough for one) would probably be much more beneficial.
