Question
Soil A-2-4 with G.I of 2.0 is better than A-2-4 with G.I of ___________
a. 10
b. 14
c. 9
d. All
Solution
The Group Index (G.I) is a measure of the suitability of a soil for use as a road material. A lower G.I indicates a more suitable soil. Therefore, Soil A-2-4 with a G.I of 2.0 is better than A-2-4 with a G.I of:
a. 10 b. 14 c. 9 d. All
The correct answer is d. All. Because all the given G.I values (10, 14, 9) are higher than 2.0, making the soil with a G.I of 2.0 better for use as a road material.
