The data in Table $1$ were obtained from laboratory test to determine a drying SWCC$.$ Graph the SWCC and determine ${}_r$ and ${}_s,$ the van Gepuchten $($VG$)$ parameters $$ and $n,$ the BrooksCorey $($B$-$C$)$ parameter $$ and the air entry suction, ${}_a.$ Evaluate equivalency of the VG and B$-$C parameters in the context of other data. What type of soil is this likely to be$?$ Explain your reasoning. Speculate on the test methods used to determine the SWCC$.$
