Q1:

In a precision traverse, included angles are measured by setting the vernier

A to read zero exactly on back station

B to read 5° exactly on back station

C some where near zero and reading both verniers on back station

D > all the above.

ANS:C - some where near zero and reading both verniers on back station

In a precision traverse, included angles are typically measured by setting the vernier to read zero exactly on the back station. This ensures that the angle measurements are accurate and consistent throughout the survey. Therefore, the correct statement is: to read zero exactly on back station.
