The Liquid Limit and Plastic Limit for the fines for each soil type are:

$\backslash$table$[[$Soil$,$LL$,$PL$],[H,55,35],[$I$,42,26],[$J$,25,19],[$L$,42,33]]$

For soil $1,$

$($a$)$ What is the fines content?

$($b$)$ What is the uniformity coefficient $C_u?$

$($c$)$ What is the predominant soil type $(C,M,S,G?$

$($d$)$ Using the Plasticity Chart on the right, what is the designation for the fine$-$grained content of this soil?
