To prove that the premises lead to the conclusion $P \wedge (P \vee Q)$, we will go through the given premises step by step using basic logical rules such as Modus Ponens, Disjunction Elimination, and others. The premises are:

1. $P \vee Q$ (Premise 1)
2. $Q \rightarrow R$ (Premise 2)
3. $P \rightarrow M$ (Premise 3)
4. $\neg M$ (Premise 4)

We need to derive the conclusion $P \wedge (P \vee Q)$.

Step-by-step derivation:

1. Restate the premises:

   • From Premise 1, $P \vee Q$, we know that either $P$ or $Q$ is true.
   • Premise 2 tells us that if $Q$ is true, then $R$ is true.
   • Premise 3 states that if $P$ is true, then $M$ is true.
   • Premise 4 tells us that $M$ is false (i.e., $\neg M$).

2. Using $\neg M$ and $P \rightarrow M$:

   • Premise 4 gives us $\neg M$.
   • From Premise 3, $P \rightarrow M$, using Modus Tollens (if $P \rightarrow M$ and $\neg M$, then $\neg P$), we can conclude: $\neg P$

3. From $\neg P$, deduce $Q$:

   • From $P \vee Q$ (Premise 1), since $\neg P$, we must conclude that $Q$ is true (by Disjunction Elimination). $Q$

4. From $Q$, apply $Q \rightarrow R$:

   • Now that we know $Q$ is true, we can use Premise 2, $Q \rightarrow R$, and apply Modus Ponens to deduce: $R$

5. Show the conclusion $P \wedge (P \vee Q)$:

   • Now, let’s check what we need for the conclusion $P \wedge (P \vee Q)$.
   • The first part of the conclusion is $P$, which we don’t have (we actually have $\neg P$). So, we cannot directly prove $P$ is true.
   • However, for the second part, $P \vee Q$, we already know from Premise 1 that $P \vee Q$ is true.

   Therefore, this argument does not seem to support the conclusion $P \wedge (P \vee Q)$ as is, because we derived $\neg P$.

Conclusion:

The premises given do not directly lead to the conclusion $P \wedge (P \vee Q)$. Instead, the steps show that $P$ is false and $Q$ is true, which conflicts with the desired conclusion. Therefore, the conclusion cannot be validly inferred from the premises as written.

Tip: Always identify whether the premises lead to a direct contradiction before attempting a proof.
