Syllogism questions with solutions

6 from the 308-question pool, worked in full.

  1. 1. Statements: Some routers are switches. No switch is a modem. Conclusions: I. No router is a modem. II. Some routers are not modems. Which conclusion(s) follow?

    • A. Neither follows
    • B. Both follow
    • C. Only I follows
    • D. Only II follows ✓

    Solution. Since some routers are switches and no switch is a modem, those particular routers are not modems, so "some routers are not modems" (II) follows. It cannot be concluded that no router at all is a modem (I), since other routers outside the switch group are unaccounted for.

  2. 2. Statements: All roses are flowers. No flower is a stone. Which conclusion follows?

    • A. No rose is a stone ✓
    • B. Some stones are roses
    • C. All stones are flowers
    • D. Some flowers are stones

    Solution. Every rose is a flower, and no flower is a stone. Therefore, no rose can be a stone.

  3. 3. Statements: All violinists are musicians. No musician is unemployed. Conclusion I: No violinist is unemployed. Conclusion II: All musicians are violinists. Which conclusion(s) logically follow from the statements?

    • A. Only conclusion I follows ✓
    • B. Only conclusion II follows
    • C. Both conclusions follow
    • D. Neither conclusion follows

    Solution. Since all violinists are musicians and no musician is unemployed, no violinist can be unemployed (conclusion I). Conclusion II reverses the first statement, which does not logically follow.

  4. 4. Statements: Some doctors are teachers. All teachers are readers. Conclusion: Some doctors are readers. Is the conclusion valid?

    • A. Contradictory
    • B. Invalid
    • C. Cannot be determined
    • D. Valid ✓

    Solution. Since some doctors are teachers and all teachers are readers, those doctors who are teachers must also be readers, so the conclusion is valid.

  5. 5. Statements: Some books are pens. No pen is a table. Conclusions: I. No book is a table. II. Some books are not tables.

    • A. Only conclusion I follows
    • B. Only conclusion II follows ✓
    • C. Both conclusions follow
    • D. Neither conclusion follows

    Solution. Since some books are pens and no pen is a table, those particular books are not tables — so "some books are not tables" follows (II). But books outside the pen group could still be tables, so "no book is a table" does not necessarily follow (I fails). Only II follows.

  6. 6. Statements: All pens are pencils. No pencils are chalks. Conclusions: I. No pens are chalks. II. Some pencils are pens.

    • A. Only I follows
    • B. Only II follows
    • C. Neither follows
    • D. Both I and II follow ✓

    Solution. Since all pens are pencils and no pencils are chalks, no pens are chalks (I follows). Since all pens are pencils, some pencils are necessarily pens (II follows).
