*Question G1E06:
[97.301, ITU Radio Regulations] The frequency allocations of which ITU region apply to radio amateurs operating in North and South America?*  

*Correct Answer is  C: Region 2*  

### AI Response: (may contain errors)  

In the context of the International Telecommunication Union (ITU) and its regulations, the world is divided into three regions for the purpose of frequency allocation:

1. **Region 1**: Covers Europe, Africa, the Middle East, and parts of northern Asia.
2. **Region 2**: Covers the Americas, including North and South America, as well as Greenland and some of the eastern Pacific islands.
3. **Region 3**: Covers Asia and the Pacific, including Australia and New Zealand.

### Explanation:

- **Correct Answer: C: Region 2**
  - **Why it's correct**: Region 2 is designated for the Americas, which includes both North and South America. Therefore, the frequency allocations for radio amateurs operating in these areas fall under ITU Region 2.

- **Why the other choices are incorrect**:
  - **A: Region 4**: There is no Region 4 in the ITU's division of the world. The ITU only has three regions.
  - **B: Region 3**: This region covers Asia and the Pacific, not the Americas. Therefore, it does not apply to North and South America.
  - **D: Region 1**: This region includes Europe, Africa, and parts of Asia, which are not relevant to the Americas.

### Useful Rule of Thumb:

- **Remember the ITU Regions**:
  - **Region 1**: Europe, Africa, Middle East, northern Asia
  - **Region 2**: The Americas (North and South America)
  - **Region 3**: Asia and the Pacific

Understanding these regions is crucial for knowing which frequency allocations apply to different parts of the world, especially for amateur radio operators.
