A site is underlain by two layers. The water table is located $2$ meters below the ground

surface. The top layer is $6$m thick and is composed of a clayey sand with OCR $=2$ and $=38.$

The bottom layer is $10$ thick and is composed of sand with OCR $=1$ and $=36.$

A$.$ Determine the lateral stress ratio at rest for the clayey sand layer. Circle your answer.

B$.$ Determine the elastic soil modulus of the sand layer. Circle your answer.
