The correct answer is: Only conclusion II follows.
The first statement is “All poles are guns.” This means that every pole is a gun. The second statement is “Some boats are not poles.” This means that there are some boats that are not poles.
From these two statements, we can conclude that some boats are not guns. This is because the first statement tells us that all poles are guns, and the second statement tells us that some boats are not poles. Therefore, some of the things that are not poles must be boats. This means that some boats are not guns.
However, we cannot conclude that all guns are boats. This is because the first statement only tells us that all poles are guns, and it does not tell us anything about boats. Therefore, it is possible that there are some things that are guns but are not boats.
In conclusion, only conclusion II follows.
