Answer:
Part (A) True
Part (B) False
Part (C) True
Step-by-step explanation:
Consider the provided information.
If both the statements are either true or false then the biconditionals are true. Otherwise biconditionals are false.
Part (A) 1 + 1 = 3 if and only if monkeys can fly.
Consider the first statement: 1+1=3 (This is a False statement)
Consider the second statement: "monkeys can fly" (This is also a False statement)
True: First statement is false and the second statement is also false, Thus, making the biconditional true.
Part (B) If birds can fly, then 1 + 1 = 3.
Consider the first statement: "birds can fly" (This is true statement)
Consider the second statement: 1 + 1 = 3 (This is a False statement)
False: First statement is true, but second statement is false, making everything false.
Part (C) If 1 + 1= 3, then pigs can fly.
Consider the first statement: 1+1=3 (This is a False statement)
Consider the second statement: "pigs can fly" (This is also a False statement)
True: First statement is false and the second statement is also false, Thus, making the biconditional true.
