Hey.. im stuck on this question, does anyone know how to solve it? Thank you!:)

Symbolization and Testing Validity (30 pts.) (1) Using the abbreviations provided, symbolize each sentence of the following argument. Make sure that your symbolizations are well-formed (20 pts.). (2) Use a partial truth table to determine whether the argument is valid or invalid and explicitly state one or the other (8 pts.). (3) If there is a counterexample (i.e. a valuation that shows the argument is invalid), then identify the truth-value assigned to each capital letter; otherwise, write "no counterexample (2 pts.). Be sure to answer all three parts of the question. You must show your work. Let: G = The fog rolls into Golden Gate Park; W = It's windy on the coast; C = The inland temperatures stay cool; H = The inland atmospheric pressure stays highi M=The coasta marine layer breaks up. If neither the fog rolls into Golden Gate Park nor it's windy on the coast, the coastal marine layer will not break up. The inland temperatures stay cool if and only if the inland atmospheric pressure stays high. It will be windy on the coast only if inland temperatures stay cool. Therefore, it's not the case that the inland atmospheric pressure stays high unless the coastal marine layer will not break up. DEC 12 .. 8,463
