After securing the base plate if needed, dig the test hole into the soil through flanged center hole. Which of the following characteristics are false? A. The hole depth will provide a representative sample of the soil. B. A depth of approximately 1½ - 2 inches has been found to be sufficient. C. The sides of the hole should slope slightly inward. All of the above. A and B.
Understand the Problem
The question is asking to identify which statements about digging a test hole in the soil are false. It provides several options regarding the depth and characteristics of the hole and requires analysis to determine the correct answer.
Answer
Characteristics B and C are false.
The false characteristics are: A depth of approximately 1½ - 2 inches has been found to be sufficient (B) and the sides of the hole should slope slightly inward (C).
Answer for screen readers
The false characteristics are: A depth of approximately 1½ - 2 inches has been found to be sufficient (B) and the sides of the hole should slope slightly inward (C).
More Information
In soil testing, a depth of 1½ - 2 inches is typically insufficient to provide a truly representative sample, and the sides of the hole should not slope inward, as this may impact the accuracy of measurements.
Tips
A common mistake is assuming shallow depths are sufficient for soil analysis or that sloping sides do not affect results.
