The correct answer is

The conclusion must be based on observation and experiment.

To determine which given characteristic is not associated with deductive reasoning, we need to understand what deductive reasoning entails.

Deductive reasoning is a logical process where the conclusion is based on the concordance of multiple premises that are generally assumed to be true. Here are key characteristics:

  • The conclusion should be supported by the premise/premises.
  • The conclusion must follow from the premise/premises necessarily.
  • The argument may be valid or invalid, meaning the logic may or may not preserve the truth depending on the structure.

Let's now analyze each option:

  1. The conclusion must be based on observation and experiment. - This is a characteristic of inductive reasoning, not deductive reasoning. Inductive reasoning involves forming generalizations based on observations and experiments, thus this statement is not true for deductive reasoning.
  2. The conclusion should be supported by the premise/premises. - This is a fundamental characteristic of deductive reasoning; the conclusion follows logically from the premises.
  3. The conclusion must follow from the premise/premises necessarily. - In deductive reasoning, if the premises are true, the conclusion must also be true by necessity.
  4. The argument may be valid or invalid. - This is true for deductive reasoning because validity is concerned with whether the conclusion logically follows from the premises.

Upon evaluation, the characteristic which is not applicable to deductive reasoning is: The conclusion must be based on observation and experiment. This is typically related to inductive reasoning. Therefore, the correct answer is:

The conclusion must be based on observation and experiment.
