Question

1. if it is raining, then the concert will be held indoors.

if the concert is held indoors, then the fireworks will be canceled.
∴ if it is raining, then the fireworks will be canceled.

$j \
ightarrow k$
$k \
ightarrow l$
$\therefore j \
ightarrow l$

$j \
ightarrow k$
$k \
ightarrow l$
$\therefore j \
ightarrow l$

3b hence determine whether the argument is valid or invalid.

Explanation:

This argument uses the logical rule of hypothetical syllogism, where if $j \Rightarrow k$ and $k \Rightarrow l$, then $j \Rightarrow l$ necessarily follows. This is a valid deductive structure where the conclusion logically follows from the premises.

Answer:

A. Valid
