Group I lists tools/instruments, while Group II lists methods of surveying. Match the tool/instrument with the corresponding method of surveying. Group I: P. Alidade Q. Arrow R. Bubble tube S. Stadia hair. Group II: 1. Chain surveying 2. Levelling 3. Plain table surveying 4. Theodolite surveying

1. P - 3; Q - 2; R - 1; S - 4
2. P - 2; Q - 4; R - 3; S - 1
3. P - 1; Q - 2; R - 4; S - 3
4. P - 3; Q - 1; R - 2; S - 4

Correct answer: P - 1; Q - 2; R - 4; S - 3

Solution

Each instrument is characteristic of a specific surveying method. Arrow is used in chain surveying, bubble tube in levelling, alidade in plain table surveying, and stadia hairs in theodolite surveying.
