What procedure is used to ensure an accurate reading of an unknown elevation?

Start the reading by placing the rod on the unknown elevation and work back to the benchmark.
Start the reading by placing the builders level on the benchmark, then take the reading of the unknown elevation.
Start by taking a reading on the benchmark then take the reading on the unknown elevation, move level and take both reading again to confirm elevation.
Start by taking a reading on the benchmark then take the reading on the unknown elevation, turn level and take the reading at the benchmark to confirm elevation.

The correct answer is: Start by taking a reading on the benchmark then take the reading on the unknown elevation, move level and take both reading again to confirm elevation.

When using a builder's level to determine the elevation of an unknown point, it is important to take multiple readings to ensure accuracy. Option A, starting the reading on the unknown elevation and working back to the benchmark, does not allow for any confirmation of the initial reading. Option B, starting on the benchmark and then taking the reading on the unknown elevation, does not account for any potential errors that may occur while moving the level. Option D, taking a reading on the unknown elevation and then turning the level to take a reading on the benchmark, also does not allow for confirmation of the initial reading. Option C, however, is the most accurate procedure as it involves taking readings on both the benchmark and the unknown elevation multiple times, and then moving the level to take readings again to confirm the elevation. This method helps to minimize any potential errors and ensure an accurate reading.
