A) if only conclusion I follows.
B) if only conclusion II follows.
C) if either conclusion I or II follows.
D) if neither conclusion I nor II follows.
E) if both conclusion I and II follow.
Correct Answer: B
Solution :
Some teachers are lecturers (I) + some lectures are demonstrators (I) = I + I = No conclusion. But the possibility in 11 exists. Hence conclusion II follows. Again, some lecturers are demonstrators (I) + No demonstrator is a professor [E] = 1 + E = O = some lecturers are not professors (O). Hence conclusion I does not follow.You need to login to perform this action.
