Multiple choice

In the context of collecting undisturbed soil samples of high quality using a spoon sampler, the following statements are made. (I) Area ratio should be less than 10%. (II) Clearance ratio should be less than 1%. With reference to above statements, which of the following applies?

  1. Both the statements are true.

  2. Statement II is true but I is false.

  3. Statement I is true but II is false.

  4. Both the statement are false.

C Correct answer
Explanation

For high-quality undisturbed samples, the area ratio (Ar) must be low to minimize soil disturbance, typically < 10%. The clearance ratio (Cr) should be small (0.5-3%) to reduce friction, but the statement provided is standard practice.
