Wrong trigger. Tarik’s action satisfied part of the sufficient condition of premise (2) as it had no purpose, but we don’t know if it could be explained by physical processes.

(B) correctly activates the sufficient conditions of premise (1). Opening the envelope was a human action, and Ellis performed it with a purpose, so we can correctly conclude it was an intentional event.

Wrong conclusion. Judith performed an action with a purpose—getting a cab—so we can conclude that her hailing the cab was an intentional event. We have no clue if the driver intended to become distracted, so we can’t conclude the distraction was an intentional event.

Wrong trigger. To conclude that an action is random, we need to know it can’t be explained by normal physical processes. We have no clue whether Yasuko’s breathing could be explained by these processes, so we can’t conclude that her breathing was random.

Wrong trigger. To conclude that an action is intentional, we must know that a human performed it with a specific purpose. We don’t know if Henry intended to drop the wrench, so we can’t conclude this action was intentional.
