Read the given statement(s) and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).
Statements:
Some fans are cars.
No car is a bus.
Conclusions:
(I) Some fans are buses.
(II) Some cars are fans.
Both conclusions (I) and (II) follow
Only conclusion (I) follows
Neither conclusion (I) nor (II) follows
Only conclusion (II) follows
Correct answer
Only conclusion (II) follows
