Answer to Question 1

TRUE

Answer to Question 2

No, this was not a controlled experiment, so no determination of cause and effect can be made. Perhaps people in better moods are more likely to be runners, or perhaps something in their body chemistry makes some people enjoy running and also affects their personality.
