Show answer and explanation

Correct answer: (A) The first reading from a level station is a foresight.

Explanation

The first staff reading after setting up a level is a backsight on a point of known elevation. A foresight is usually the last reading before moving the instrument. The other three statements describe standard surveying principles, so **A** is the incorrect statement.
