Which of the following statement(s) is/are CORRECT?

Swell potential of soil decreases with an increase in the shrinkage limit.
Both loose and dense sands with different initial void ratios can attain similar void ratio at large strain during shearing.
Among the several corrections to be applied to the SPT-N value, the dilatancy correction is applied before all other corrections.
In electrical resistivity tomography, the depth of current penetration is half of the spacing between the electrodes.

Correct answer: Both loose and dense sands with different initial void ratios can attain similar void ratio at large strain during shearing.

Solution

Loose and dense sands can reach a similar void ratio under large strain conditions due to the rearrangement of particles during shearing, which allows for a convergence in their structural behavior despite their initial differences.
