Given the argument and its Euler diagram below, determine whether the syllogism is valid or invalid.
All roads come to an end.
Carrollton Avenue is a road.
Carrollton Avenue comes to an end.
I'm assuming that this is your Euler diagram:
Carrollton Ave is part of the set of all roads.
If it is a road, then it must come to an end.
Here is a similar example.
All parallelograms are quadrilaterals.
Squares are parallelograms.
You can conclude that squares are quadrilaterals.
