Assertion and reason

Read exercise and reference answers
Questions
  1. Reason
    The premises may allow other arrangements in which it fails.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    A single supporting diagram does not prove a conclusion.
  2. Reason
    Every member of the inner class is also a member of the outer one.
    Verdict
    Both are true; the reason explains the assertion.
    Assertion
    Nested circles picture a universal affirmative.
  3. Reason
    A circle represents a class of things.
    Verdict
    The assertion is false and the reason is true.
    Assertion
    The size of a circle carries information.
The reason must genuinely explain the assertion. Source: Logic: Deductive and Inductive, Carveth Read (1898), public domain.
