Question 30: Environment and Ecology
Consider the following pairs :
| Wetland/Lake | Location | |
|---|---|---|
| 1 | Hokera Wetland | Punjab |
| 2 | Renuka Wetland | Himachal Pradesh |
| 3 | Rudrasagar Lake | Tripura |
| 4 | Sasthamkotta Lake | Tamil Nadu |
How many pairs given above are correctly matched ?
AnswerUPSC’s answer is (b).
Renuka Wetland is in Himachal Pradesh (Sirmaur) and Rudrasagar Lake is in Tripura, so pairs 2 and 3 are correct. Hokera Wetland is in Jammu and Kashmir, near Srinagar, not Punjab. Sasthamkotta Lake is in Kerala (Kollam), not Tamil Nadu. Two pairs are correct.
- 1. Hokera Wetland is in Jammu and Kashmir.
- 2. Renuka Wetland is in Himachal Pradesh.
- 3. Rudrasagar Lake is in Tripura.
- 4. Sasthamkotta Lake is in Kerala.
How you could have got this
No shortcut here: in a “how many” question, ruling out options doesn’t help. Every statement has to be judged.
Which options go is worked out from UPSC’s key and the options, not by a model.
Why each option is right or wrong
- (a) Wrong. Two pairs are correct, not one.
- (b) Correct. Renuka and Rudrasagar are matched correctly.
- (c) Wrong. Hokera and Sasthamkotta are mismatched.
- (d) Wrong. Hokera and Sasthamkotta are mismatched.
