Question# 1 Part A: Come up with aninstance of argument that conforms to HS. Derive theconclusion from the given premises in the argument below by utilizing the rulesof inference (hint: use HS, MT, DS, or some other combination, as analternative is available here).         C:   B      ==================        P1:   A  V  B        P2:   C ⊃  D        P3:   A ⊃  C        P4:  ~D      ========================================================================Part B: Exercise 31 Do a Proof for thefollowing argument: Use TT for testing validity. Follow thethree steps: 1. Assign P, Q, and R to the atomic sentences in the order of appearancein the argument. 2. Formalize the argument. 3. Derive the conclusion from the premises by using the rules of inference.     P1:  If things are caused to exist, then the infinite regress of existenceis not possible.     P2:  God is not the ultimate cause of existence, only if the infiniteregress of existence is possible.     P3:  By the way, things are caused to exist.     C:   Therefore, God is the ultimate cause of existence.[31-2]’Derive’ the conclusion (C) from the 3 premises (1 to 3) in aformalized argument below by employing rules of inference (i.e., proof, whereyou need to come up with additional steps beyond 3 below to lead you to theconclusion):        C.  ~T        —————————–        1.  (R V S) ⊃ (T ⊃ K)        2.  ~K        3.  R V S        —————————–Part C: Determine whether the following argument is valid or notby showing how truth tables are utilized and interpreted:[26-1]  P1:  P -> Q P2:  Q -> R  P3: ~R      ————————-        C:  ~P[26-2]  P1:  ~D  V ~F      P2:  G-> (D & F)    —————————–   C:  ~G
