In the following question below are given three statements followed by three conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: Some wall are roofs. Only few roofs are laptops. All dooms are laptops. Conclusions: I. All laptops can be roofs. II. Some Walls are dooms. III. No walls are dooms. 

In the following question below are given three statements followed by three conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: Some wall are roofs. Only few roofs are laptops. All dooms are laptops. Conclusions: I. All laptops can be roofs. II. Some Walls are dooms. III. No walls are dooms.  Correct Answer either II or III and conclusion I follow.

Conclusions:

I. All laptops can be roofs → True (only few roofs are laptops)

II. Some Walls is dooms → False (Definite is false)

III. No walls is dooms → False (Definite is false).

As conclusion II and III are complementary pairs so either or case is followed.

Hence, the correct answer is either II or III and conclusion I follow.
