Question map
Consider the following pairs : River Flows into The 1. Mekong - Andaman Sea 2. Thames - Irish Sea 3. Volga - Caspian Sea 4. Zambezi - Indian Ocean Which of the pairs given above is/are correctly matched ?
Explanation
The correct answer is Option 3 (3 and 4 only). This is determined by the geographical drainage patterns of the major rivers mentioned.
- Pair 3 is correct: The Volga is Europe's longest river. It flows through Central Russia and drains into the Caspian Sea, forming a large delta.
- Pair 4 is correct: The Zambezi is the largest river flowing into the Indian Ocean from Africa. It originates in Zambia and passes through several countries before reaching its mouth in Mozambique.
The other pairs are incorrectly matched:
- Pair 1 is incorrect: The Mekong flows through Southeast Asia and empties into the South China Sea, not the Andaman Sea.
- Pair 2 is incorrect: The Thames flows through London and empties into the North Sea, whereas the Irish Sea lies to the west of Great Britain.
Therefore, only pairs 3 and 4 are accurately matched with their respective drainage basins.
PROVENANCE & STUDY PATTERN
Guest previewThis question is a hybrid of direct NCERT recall (Volga) and basic map visualization (Mekong/Thames). It punishes 'text-only' readers who memorize river names without tracing their path on a physical map. The Volga fact acts as the anchor to eliminate 50% of the options immediately.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Explicitly states where the Mekong ends: the Mekong Delta.
- The passage names the river’s terminus (Mekong Delta) rather than the Andaman Sea, implying the Mekong does not flow into the Andaman Sea.
- Defines the Andaman Sea as the eastern extension of the Bay of Bengal (a distinct sea region).
- Shows the Andaman Sea is a separate body of water; the Mekong’s listed terminus (Mekong Delta) is not identified as the Andaman Sea in the provided passages.
Explicitly lists the Mekong River among freshwaters contributing to the South China Sea region (Mekong River included in a list alongside South China Sea rivers).
A student could use a map to note the Mekong's mouth relative to the Andaman Sea versus the South China Sea to judge whether it flows into the Andaman Sea.
Identifies the Andaman Sea as a named body of water in the region (asks which water body separates Andaman from Nicobar islands), clarifying the Andaman Sea's geographic identity.
A student could locate the Andaman Sea on a map to compare its position with the Mekong delta to see if they coincide.
Shows that some rivers in northeastern India/Myanmar region (Manipur River) join larger Myanmar river systems (Irrawaddy), illustrating that regional drainage connects to seas east of the Indian subcontinent.
A student could trace regional river systems on a map (Irrawaddy, Mekong) to determine which sea each ultimately reaches and thus infer whether Mekong reaches the Andaman Sea.
Gives a general pattern that many rivers in South/SE Asia drain into specific nearby seas (Bay of Bengal or Arabian Sea), demonstrating that regional drainage tends to reach geographically proximate seas.
Using this pattern plus a map, a student can check whether the Mekong's geographic course makes the Andaman Sea a likely outlet compared with other nearby seas (e.g., South China Sea, Bay of Bengal).
