Question

Holly told her roommate Maria, “If you make dinner tonight, then I will clean the bathroom tomorrow.” Maria spent an hour making a nice dinner. The next day Holly told Maria, “Sorry, I just don’t have time to clean the bathroom today.”

Which of the following is true about Holly’s original statement?

		It has been shown to be true.
		It might be true or it might be false. There is not enough information to tell.
		It must be assumed true because Holly didn't have time to clean the bathroom.
		It has been shown to be false.
		It is neither true nor false.

Answer 1

Holly's original statement  has been shown to be false because in her statement she said: “If you make dinner tonight, then I will clean the bathroom tomorrow.” But she didn't clean the bathroom the next day.

Answer 2

the answer is: It has been shown to be false. Because in logic, a conditional statement "If P, then Q" is false if and only if P is true and Q is false. Given that Maria did make dinner and Holly did not clean the bathroom, Holly's original statement has been shown to be false.
