solve only (D) and (E)

Question 1 Figure Q1 shows a vertical cross-section of a site. The ground water table is located at 2 m below the ground surface. Dry and saturated unit weights of the sand are 16 kN/m³ and 20 kN/m³, respectively. The clay is normally consolidated and has a saturated unit weight of 18 kN/m³ and an effective friction angle of 32°. The unit weight of water is taken as 10 kN/m³.
