Statements:
Some bells are temples.
Some temples are marbles.
Conclusions:
I. Some bells are marbles
II. No marble is a temple.
Some bells are temples (I) + Some temples are marbles (I) = no conclusion. Hence, conclusion I will not follow. Both the statements are positive statements and conclusion II is negative and we know that negative definite conclusions cannot be drawn from the positive statements. Hence, conclusion II will not follow.
