If matter is atomic, then we can observe only modes. If we do not know of the world by pure reason, then, again, we can observe only modes. Either matter is atomic or we do not know of the world by pure reason. So, we can observe only modes.
-Which of the following is the best translation into PL of this argument?
A) M ⊃ A ∼R ⊃ M
A $ \lor $ ∼R / M
B) A ⊃ M ∼R ⊃ M
A $ \lor $ ∼R / M
C) A ⊃ M R ⊃ M
A ⊃ ∼R / M
D) A ⊃ M R ⊃ M
A $ \lor $ ∼R / M
E) M ⊃ A M ⊃ ∼R
A $ \lor $ ∼R / M

- M: matter is atomic
- A: we can observe only modes
- R: we know of the world by pure reason
The argument can be translated as follows:
A premise: M ⊃ A 
B premise: ∼R ⊃ M 
Therefore: A
The argument is valid and the best translation is option B.
