Which sentences uses deductive reasoning

Answer: A sentence that uses deductive reasoning typically starts with a general statement or hypothesis and then applies that statement to a specific case to arrive at a logical conclusion. Deductive reasoning is a basic form of valid reasoning. It starts with a general statement, or hypothesis, and examines the possibilities to reach a specific, logical conclusion.

Here are two examples illustrating deductive reasoning:

1. All birds have feathers. A swan is a bird. Therefore, a swan must have feathers. 2. If all mammals are warm-blooded and whales are mammals, then whales must be warm-blooded.

In both examples, the reasoning starts with a general rule (all birds have feathers/all mammals are warm-blooded) and applies it to a specific instance (a swan/whales) to reach a conclusion (a swan must have feathers/whales must be warm-blooded).
