Fallacy of arguments

Question

Does the following argument involve a fallacy?

My garden will be healthy if I water the plants assiduously. Thus my garden will certainly be healthy, as I will indeed water the plants assiduously.

(a) undistributed middle

(b) denying the antecedent

(c) affirming the consequent

(d) no fallacy: deductively valid

Answer 1

The argument is deductively valid (though it rests on an assumption about the future).

You can reformulate it as a basic modus ponens as follows:

1. If I water the plants assiduously, my garden will be healthy
2. I will water the plants assiduously

Therefore, 3. My garden will be healthy
