Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

Give answer:

  • (B) If only conclusion II follows

  • (E) If both I and II follow.

Statements: All jungles are tigers. Some tigers are horses.

Conclusions:

  1. Some horses are jungles.
  2. No horse is jungle.
Only conclusion I follows
Only conclusion II follows
Either I or II follows
Neither I nor II follows
Both I and II follow
Answer: Option
Explanation:
Since the middle term 'tigers' is not distributed even once in the premises, no definite conclusion follows. However, I and II involve only the extreme terms and form a complementary pair. So, either I or II follows.

Here we have used major and minor term, the predicate and the subject of the conclusion. They are part of the conclusion I and II and according to the rules of syllogism they form a complementary pair. Hence the option is correct.
