Order the steps: test a syllogism

Read exercise and reference answers
Steps
  1. Write each premise in one of the forms A, E, I or O
  2. Identify the subject and predicate of each
  3. Note which terms are distributed by each premise
  4. Check whether the conclusion's terms are licensed by the premises
  5. If any term is distributed in the conclusion but not in a premise, reject it
Name the forms, check what each distributes then see whether the conclusion is licensed. Source: Logic: Deductive and Inductive, Carveth Read (1898), public domain.

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.
