True or false: reasoning from two premises

Read exercise and reference answers
Questions
  1. Statement is true
    Yes
    Statement
    A conclusion must not distribute a term the premises left undistributed.
  2. Statement is true
    No
    Statement
    'Some' statements alone can prove a universal conclusion.
  3. Statement is true
    Yes
    Statement
    A valid deduction's conclusion is contained in its premises.
  4. Statement is true
    Yes
    Statement
    True premises with a valid form give a true conclusion.
  5. Statement is true
    No
    Statement
    A valid argument can have true premises and a false conclusion.
Two particular premises alone never license a conclusion, which is why exam sets always include a universal. Source: Logic: Deductive and Inductive, Carveth Read (1898), public domain.

Assertion and reason

Read exercise and reference answers
Questions
  1. Reason
    The conversion would distribute a term that the original left undistributed.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    'Some men are not cooks' does not give 'Some cooks are not men'.
  2. Reason
    A universal negative distributes both of its terms.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    'No S is P' may be reversed freely.
  3. Reason
    Induction generalises beyond the cases actually observed.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    An inductive conclusion can be false though the evidence is true.
  4. Reason
    A universal affirmative distributes its subject.
    Verdict
    The assertion is false and the reason is true.
    Assertion
    'All S is P' may be reversed to 'All P is S'.
The reason must genuinely explain the assertion. Source: Logic: Deductive and Inductive, Carveth Read (1898), public domain.

    2. A is the universal affirmative
    3. O is the particular negative
  3. False statement
    Induction guarantees a true conclusion
    Statements
    1. Deduction draws out what premises contain
    2. Induction guarantees a true conclusion
    3. Induction generalises beyond the evidence
The false line always over-reverses a statement. Source: Logic: Deductive and Inductive, Carveth Read (1898), public domain.
