Read the following premise and answer if the hypothesis is true.
A man in jeans and a blue long-sleeved shirt is on his phone while leaning on the edge of a building.
Hypothesis: the man is a spy. Is the answer "Yes", "No", or "It's impossible to say"? Respond with only the answer and no additional text.
It's impossible to say
It's impossible to say. The man's appearance and behavior do not provide enough evidence to determine if he is a spy or not.
