Discussion

Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statement:
I. Some persons are good.
II. Some persons are intelligent.

Conclusion:
I. Some intelligent people are good.
II. Some good people are intelligent.

  • A.Conclusions I and II follow.
  • B.Only conclusion II is correct.
  • C.Only conclusion I is correct.
  • D.Neither of the two conclusions is correct.

Answer: D

Both statements start with 'Some persons', so one group of persons are good and some persons (maybe the same ones, maybe not) are intelligent. Nothing links the good persons and the intelligent persons, since the two groups are not stated to overlap. A Venn diagram can show two separate circles inside the larger circle of persons, in which no intelligent person is good, so neither 'Some intelligent people are good' nor 'Some good people are intelligent' has to be true. Two particular (some) premises never give a conclusion in syllogisms, so neither conclusion follows. The answer is the fourth option, neither of the two conclusions is correct.
