What is deductive reasoning?

1. The process of deriving general principles from specific observations

2. The process by which conclusions are drawn by logical inference from given premises

3. A method of reasoning that focuses only on observable phenomena

4. A form of creative thinking beyond traditional logic

The correct answer is: The process by which conclusions are drawn by logical inference from given premises

Deductive reasoning is a logical process whereby conclusions are drawn from premises that are understood to be true. In this context, it involves taking general principles or statements and applying them to specific instances to reach a conclusion. This method depends on the validity of the initial premises; if they are true and the reasoning is sound, the resulting conclusion must also be accurate. For example, if one premise states that all mammals are warm-blooded and another premise asserts that whales are mammals, one can deduce the conclusion that whales are warm-blooded. This structured approach contrasts with other forms of reasoning, such as inductive reasoning, which starts from specific observations to develop broad generalizations. The other options touch on aspects of reasoning but do not accurately define deductive reasoning. The first choice describes inductive reasoning instead, while the third option narrows the scope to observable phenomena rather than logical premises. The fourth choice discusses creative thinking, which diverges from the strict logical framework characteristic of deductive reasoning.
