When you were a baby, flashing lights on a cop car probably didn't scare you or make your heart race. Over the years, you've learned that flashing lights usually mean that
someone is in trouble (which can lead to expensive tickets, jail time, scolding from
your parents, etc.) or in danger. Many people, when driving on the freeway, will feel
their heart rate increase and possibly begin perspiring if they see a police car behind
them with its lights flashing (even if they aren't committing a crime). What is the UCS
of this situation?

a) getting in trouble
b) police lights
c) heart rate increase, begin sweating (happening naturally when you get in
trouble)
d) heart rate increase, begin sweating (because you have begun to associate
police lights with getting in trouble)
