answer using the code given below the lists:
List I
A.
C. N. R. Rao
B. Jagdish Bhagwati
C. G. N. Ramchandran
D. Ashok
List II
1. Telecommunication
2. Physics
3. Economics
4. Solid State Chemistry and Material Science
Code:
- (a) A - 4 B - 3 C - 2 D - 1
- (b) A - 2 B - 1 C - 4 D - 3
- (c) A - 4 B - 1 C - 2 D - 3
- (d) A - 2 B - 3 C - 4 D - 1
Answer: (a) A - 4 B - 3 C - 2 D - 1
Explanation
Indian scientists and scholars with their areas of work
| Person | Area of work |
|---|---|
| A. C. N. R. Rao | Solid State Chemistry and Material Science (4) |
| B. Jagdish Bhagwati | Economics (3) |
| C. G. N. Ramachandran | Physics (2), protein structure and the Ramachandran plot |
| D. Ashok (Jhunjhunwala) | Telecommunication (1) |
So the correct code is A-4, B-3, C-2, D-1.
Answer: (a) A-4 B-3 C-2 D-1.
Why each option is right or wrong
- (a) CORRECT. C. N. R. Rao-Solid State Chemistry, Bhagwati-Economics, Ramachandran-Physics, Ashok-Telecommunication.
- (b) Incorrect. This swaps C. N. R. Rao's area with Ramachandran's.
- (c) Incorrect. This gives Bhagwati telecommunication and Ashok economics.
- (d) Incorrect. This gives C. N. R. Rao physics and Ramachandran solid state chemistry.
Key point
C. N. R. Rao works in solid state chemistry, Bhagwati in economics, G. N. Ramachandran in physics and Ashok in telecommunication.
Remember
C. N. R. Rao-Solid State Chemistry, Bhagwati-Economics, Ramachandran-Physics.
Common mistakes
- Treating C. N. R. Rao as a physicist because of his materials work.
- Linking Bhagwati with the physical sciences.
- Not recalling Ramachandran's biophysics background in physics.
Exam tip
CNR Rao - solid state chemistry; Bhagwati - trade economist; Ramachandran - physics/biophysics.
