Answer:

A.   Simplification

B.   Disjunctive Syllogism

C.  Modus Ponens

D.  Addition

E.  Hypothetical Syllogism

Explanation:

(a) Given that k = the proposition “Kangaroos live in Australia.”

m = the proposition “Kangaroos are marsupials.”

Hence, k ∧ m→ k = Simplification

(b) Given that k = the proposition ”Hotter than 100 degrees today.”

m = the proposition ”Pollution is dangerous.”

Hence (k ∨ m) ∧ ¬k → m = Disjunctive syllogism

(c) Given that k be the proposition ”Linda is an excellent swimmer.”

m = the proposition ”Can work as a lifeguard.”

Hence, k ∧ (k → m) → m = Modus ponens

(d) Given that k =the proposition ”Steve will work at a computer company this summer.”

m = the proposition ”Steve will be a beach bum.”

Hence, k → k ∨ m. = Addition

e) Given that k = the proposition " I work all night on this homework."

m = the proposition "I will answer all the exercises"

n = the proposition "I will understand the material."

(k → m) ∧ (m → n) → (k → n) = Hypothetical Syllogism
