First-order logic representation:L(x) - "x owns lands" V(x) - "x owns vehicles" T(x) - "x pays tax"∀x (L(x) ∨ V(x) → T(x)) ∃x (¬V(x) ∧ T(x)) ¬∃x T(x)Conjunctive normal form (CNF):(¬L(x) ∨ ¬V(x) ∨ T(x)) (¬V(x) ∨ T(x)) ¬T(x)2.) Sarath argues that Kamal does not own a vehicle. To justify this using the method of contradiction, let's assume that Kamal does own a vehicle (V(Kamal)).From the given information, we have: ∀x (L(x) ∨ V(x) → T(x)) ∃x (¬V(x) ∧ T(x)) ¬∃x T(x)By substituting Kamal for x, we can derive the following: (L(Kamal) ∨ V(Kamal) → T(Kamal)) (¬V(Kamal) ∧ T(Kamal)) ¬T(Kamal)Now, we have the assumption V(Kamal) and the derived statement (¬V(Kamal) ∧ T(Kamal)). This leads to a contradiction since Kamal cannot both own a vehicle and not own a vehicle at the same time.Therefore, based on the method of contradiction, we can conclude that Sarath's argument is correct, and Kamal does not own a vehicle.</blockquote>
