Bangkok
Hanoi
Jakarta
Singapore
Select the correct answer using the code given below.
4-2-1-3
3-2-4-1
3-4-1-2
4-3-2-1
Correct Answer: C
Detailed Solution
To determine the south-to-north sequence, the latitudes of the cities should be considered:
City | Country | Approximate latitude | Geographical position |
Jakarta | Indonesia | 6.2° South | South of the Equator, on the north-western coast of Java |
Singapore | Singapore | 1.3° North | Immediately north of the Equator, at the southern end of the Malay Peninsula |
Bangkok | Thailand | 13.8° North | In the delta region of the Chao Phraya River |
Hanoi | Vietnam | 21.0° North | In northern Vietnam, in the Red River delta region |
Therefore, the correct sequence from south to north is:
Jakarta → Singapore → Bangkok → Hanoi
Important concept: The north-south position of a place is determined by its latitude, not its longitude. Jakarta is the only one of these four cities situated south of the Equator, while Hanoi is the northernmost.
