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.

'passage':The lungs take up most of the space in the chest cavity, which extends from the collarbones to the diaphragm (see Figure 2). The organs of the chest are protected by the ribs. The area between the lungs in the middle of the chest is called the mediastinum. It contains the heart, windpipe (trachea), food pipe (esophagus), blood vessels, and many lymph nodes. Examination of the lymph nodes in the mediastinum is an important part of the lung cancer staging process and is discussed in Chapter 4: Lung Cancer Diagnosis and Staging.
