  1. Question 1

    Q1. If all A are B and some B are C, which conclusion is logically valid?

    • A) All A are C.
    • B) Some A are C.
    • C) No A are C.
    • D) Not enough information to conclude.

    Answer: Not enough information to conclude.

    Explanation: D. The premises don't establish a direct A-C relationship. A/B/C are invalid because they assume connections not supported by 'some' and 'all' overlap.
