  • Question

  • Statements: All trees are flowers. No flower is fruit. All branches are fruits.

    Conclusions:

    1. Some branches are trees.
    2. No fruit is tree.
    3. No tree is branch.


  • Options
  • A. None follows
  • B. Only either I or III follows
  • C. Only II follows
  • D. Only either I or III, and II follow
  • E. None of these

  • Correct Answer
  • None of these 

    Explanation
    All trees are flowers. No flower is fruit.

    Since both the premises are universal and one premise is negative, the conclusion must be universal negative (E-type) and should not contain the middle term. So, it follows that 'No tree is fruit'. II is the converse of this conclusion and so it follows.

    All branches are fruits. No flower is fruit.

    Since both the premises are universal and one premise is negative, the conclusion must be universal negative (E-type) and should not contain the middle term. So, it follows that 'No branch is flower'.

    All trees are flowers. No branch is tree.

    As discussed above, it follows that 'No tree is branch'. So, III follows.

    Hence, both II and III follow.
