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':1093637
'query':lactose symptoms
'pid':7939734
'passage':The Trp operon in E. coli is turned on by default. The lac operon in E. coli is turned off when lactose is not present. A repressor binds to the operator and prevents RNA polymerase from binding to the promoter. When allolactose (closely related to lactose) is present, it binds to the repressor and prevents the repressor from binding. In this way, the presence of lactose allows the operon to be turned on to express the genes need to use lactose.
    Output:
