Pick up the correct statement from the following:
The range of water content between the liquid limit and plastic limit, is called plasticity index.
The ratio of the liquid limit minus the natural water content to the plasticity index of soils, is called consistency index
The ratio of natural water content minus its plastic limit to its plasticity index is called liquidity index
The ratio between plasticity index and flow index (i.e. slope of flow curve in case of liquid limit), is called toughness index
All the above.

A triaxial shear test is prefered to direct shear test, because
it can be performed under all three driange conditions with complete control
precise measurement of pore pressure and change in volume during test, is not posible
stress distribution on the failure plane, is non uniform
none of these.
