*Question E1B10:
[97.407] What frequencies are authorized to an amateur station operating under RACES rules?*  

*Correct Answer is  A: All amateur service frequencies authorized to the control operator*  

### AI Response: (may contain errors)  

Under the Radio Amateur Civil Emergency Service (RACES) rules, amateur stations are authorized to operate on all amateur service frequencies that are authorized to the control operator. This means that the control operator can use any frequency they are normally allowed to use under their license class.

### Explanation:

1. **Correct Answer: A**  
   - **All amateur service frequencies authorized to the control operator**: This is correct because RACES operations are conducted under the same frequency privileges as the control operator's license class. There are no special or restricted frequencies specifically designated for RACES; instead, operators use their existing privileges.

2. **Why Other Choices Are Incorrect:**
   - **B: Specific segments in the amateur service MF, HF, VHF, and UHF bands**: This is incorrect because RACES does not limit operations to specific segments within these bands. Operators can use any frequency within their license privileges.
   - **C: Specific local government channels**: This is incorrect because RACES does not authorize the use of local government channels, which are typically outside the amateur bands.
   - **D: All these choices are correct**: This is incorrect because choices B and C are not correct, as explained above.

### Key Points:
- RACES operations are conducted on the same frequencies that the control operator is authorized to use.
- There are no special frequency allocations for RACES; it relies on the existing amateur radio band allocations.

Understanding these points will help you correctly identify the frequency privileges under RACES rules.
