Classification and properties of soil in deatils

A soil is classified as CL according the United Soil Classification System(USCS). The plasticity Index (PI) of the soil is 20%. What is the maximum value of the Liquid Limit (LL) of the soil?   Question 9 options:   29%   47%   30%   20%

Use the USDA soil classification triangle to determine the textural soil class designations with the distributions of particle sizes shown in the table (unit is mm).

Describe the nature and properties of the 4 types of soil colloids. Be sure to include a description of the physical and chemical characteristics associated with each of the four types.

I need the answer as soon as possible

(1). What is the phenomenon of liquefaction of the soil?(2). Explain the liquefaction phenomenon of the soil body by the principle of the soil mechanics.
