Statements:
(I) No tree is desktop
(II) All desktops are computers
Conclusion:
(I) Some desktops are tree
(II) Some trees are computer
Which conclusion will follow on the basis of given statement ?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Neither I nor II follows
A conclusion follows only if it is true in every diagram that fits both statements. One diagram in which a conclusion fails is enough to reject it.
(I) Some desktops are tree Does not follow. Statement (I) says no tree is a desktop, so no desktop can be a tree either; the conclusion contradicts it.
(II) Some trees are computer Does not follow. The desktops are computers, but trees are only kept away from desktops; the statements say nothing about trees and the other computers. In the diagram above no tree is a computer, and both statements still hold.
