Answer:
Given argument is valid
Step-by-step explanation:
In venn diagram
M=Mammals
R=Reptiles
G=Gators
Given that
No mammals are reptiles ,So in the diagram we indicates by cross sign(x).Also given that some reptiles are gators ,so venn diagram of reptiles and gators will cross each other.
But from the above statement we can say that those gators are reptiles can not be mammals but those are not reptiles they can be mammals.Hence some gators are not mammals.
So given argument is valid
