Question

Statement (I): Fine-grained soils are difficult to drain.
Statement ( ll): Capillary forces act on pore water.

Directions: Each of the next items consists of two statements, one labelled as the Statement (I) and the other as Statement (II). Examine these two statements carefully and select the answers to these items using the codes given below :
Codes:

• A. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
• B. Both Statement (I) and Statement (11) are individually true but Statement (II) is not the correct explanation of Statement (I)
• C. Statement (I) is true but Statement (II) is false
• D. Statement (I) is false but Statement (II) is true

Answer 1

The correct option is A Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)

(a)
Fine grained soils are more difficult to drain than coarse grained soils because the voids in the former are so small that the contained water is strongly held by capillary attraction. while in soil with large grains this force does not act so strongly.
