Question and options

Some statements are given followed by four conclusions. Find out which of the conclusions logically follow from the given statements.
Statements: No educationists are researchers. All researchers are teachers.
Conclusions:
I. No teacher is researcher
II. No teacher is educationist
III. Some researchers are teachers
IV. Some teachers are researchers
  1. Only II follows
  2. None follows
  3. Either I or III follows
  4. Only III and IV follow

Answer and explanation

Correct answer: D - Only III and IV follow
All researchers are teachers, so some researchers are teachers (III) and some teachers are researchers (IV). I contradicts the premise, and II is not certain because teachers who are not researchers may be educationists. Only III and IV follow.
