*Question E1B05:
[97.3] What is the National Radio Quiet Zone?*  

*Correct Answer is  C: An area surrounding the National Radio Astronomy Observatory*  

### AI Response: (may contain errors)  

The National Radio Quiet Zone (NRQZ) is a designated area that helps protect radio astronomy observations from interference. 

### Correct Answer: 
**C: An area surrounding the National Radio Astronomy Observatory**

- The NRQZ is primarily established to minimize radio frequency interference (RFI) for the National Radio Astronomy Observatory (NRAO) located in Green Bank, West Virginia. This area is crucial for radio astronomers who need a quiet environment to observe celestial phenomena without man-made noise.

### Why the Other Choices are Incorrect:
- **A: An area surrounding the FCC monitoring station in Laurel, Maryland**  
  - This is incorrect because the NRQZ is not specifically designed to protect an FCC monitoring station. The focus is on radio astronomy rather than monitoring.

- **B: An area in New Mexico surrounding the White Sands Test Area**  
  - While White Sands is a significant military testing area, it is not designated as the NRQZ. The NRQZ is specifically related to the needs of radio astronomy.

- **D: An area in Florida surrounding Cape Canaveral**  
  - Cape Canaveral is known for space launches and related activities, but it does not have the same restrictions or purpose as the NRQZ, which is focused on protecting radio astronomy.

### Summary:
The NRQZ is essential for ensuring that radio telescopes can operate without interference from other radio signals. Understanding the purpose and location of the NRQZ is important for the Extra Class exam, as it highlights the balance between technological development and scientific research.
