      B Both the conclusions I and II follow Correct Answer Incorrect Answer
      C Neither conclusion I nor II follows Correct Answer Incorrect Answer
      D Only conclusion III follows Correct Answer Incorrect Answer
      E Either conclusion I or II follows Correct Answer Incorrect Answer

      Solution

      Some pilot are engineer (I) + At least some engineer are scientist (I) → No conclusion. Hence conclusion I does not follow. Some pilot are engineer (I) → Conversion → Some engineer are pilot (I) + No pilot is lawyer (E) → Some engineer are not lawyer (O). Hence conclusion II does not follow. At least some engineer are scientist (I) → Conversion → Some scientist are engineer (I) + Some engineer are not lawyer (O) → Probable conclusion → Some lawyer may be scientist (I). Hence conclusion III follows.
