Question

    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.

    Statements:

    Some cards are postcards.

    Some cards are envelopes.

    All envelopes are copies.

    Conclusions:

    I. Some copies are envelopes.

    II. Some postcards are copies.

    III. Some cards are copies.

    A Only conclusions II and III follow Correct Answer Incorrect Answer
    B Only conclusions I and III follow Correct Answer Incorrect Answer
    C Only conclusion I follows Correct Answer Incorrect Answer
    D Only conclusions I and II follow Correct Answer Incorrect Answer

    Solution

    All envelopes are copies (A) → Conversion → Some copies are envelopes (I). Hence conclusion I follows. Some cards are postcards (I) → Conversion → Some postcards are cards (I) + Some cards are envelopes (I) → No conclusion. Hence conclusion II does not follow. Some cards are envelopes (I) + All envelopes are copies (A) → Some cards are copies (I). Hence conclusion III follows.
