Q. Which of the following pairs of country borders matched to latitude parallels are correctly matched?

1. 17th Parallel – North and South Vietnam
2. 20th Parallel – Sudan and Egypt
3. 22nd Parallel – Sudan and Libya
4. 25th Parallel – Mali-Mauritania
5. 31st Parallel – Iraq and Iran

Select the correct answer using the codes given below:
Answer: Only 1, 4 & 5
Notes: The 17th parallel divided North and South Vietnam. The 22nd parallel forms part of the Sudan-Egypt border, not Sudan-Libya. The 25th parallel marks the northern section of the Mali-Mauritania border. The 31st parallel demarcates the Iraq-Iran border. The 20th parallel is not the Sudan-Egypt border. Thus, only statements 1, 4, and 5 are correct.
