****READ INSTRUCTIONS AT START OF EACH SECTION CAREFULLY!! **** In 1–4, assign truth values to the variables to make the premises true. Then, demonstrate that the arguments are valid by showing that true premises must lead to a true conclusion. 1. - Premises: - \( p \rightarrow q \) - \( q \rightarrow r \) - \( p \) - Conclusion: - \(\therefore r \) 2. - Premises: - \( a \lor b \) - \( b \rightarrow \sim c \) - \( c \) - Conclusion: - \(\therefore a \) 3. - Premises: - \( j \rightarrow i \) - \( \sim j \rightarrow k \) - \( \sim k \) - Conclusion: - \(\therefore i \) 4. - Premises: - \( d \land \sim h \) - \( h \lor y \) - \( y \rightarrow n \) - Conclusion: - \(\therefore n \)
