Which of the following images would most likely evoke a scary mood?
a. the opening of a creaky door in a deserted house
b. the smell of baking bread in a farmer’s kitchen
c. two swans on a lake staring at each other
d. a cowboy asleep under a full moon

This is a question that you should just have to use your own opinion. Which of these would you most likely see in a horror/suspense movie?

two swans romantically together? nope
a cowboy sleeping? i don't think so
