helen was seen exiting the alley after a robbery had taken pl it follows that helen committed the robbery.

Explanation:

A deductive argument uses general principles to reach a specific conclusion, with the conclusion necessarily following if the premises are true.

• The first option is inductive (based on past experiences to predict the future).
• The second option: Premise 1: Traffic is heavy today. Premise 2: When traffic is heavy, I take the bus. Conclusion: I will take the bus today. This follows a deductive structure (modus ponens: if P then Q, P, so Q).
• The third option is inductive (past snow on birthdays to predict this year).
• The fourth option is inductive (correlation to infer causation, not a necessary conclusion from premises).

Answer:

B. Traffic is very heavy today. When traffic is heavy, I take the bus to work. I will take the bus to work today.
