Pick up the correct statement from the following:
When water table is above the base of a footing, the dry weight m should be used for soil below water table
When water table is located somewhat below the base of a footing, the elastic wedge is partly of moist soil and partly of submerged soil, and a suitable reduction factor is used
When water table is just at the base of the footing, no reduction factor is used
None of these.

Pick up the correct statement from the following :
In soils, the flow index indicates variation in shear strength with water content
Liquid limit minus plastic limit, is known as plasticity index of the soil
Plastic limit minus shrinkage limit, is known as shrinkage index of the soil
The ratio of the plasticity index to the flow limit, is known as toughness index of the soil
All the above.
