premise: Two men in matching formal wear stand next to each other, smiling. hypothesis: two friends are getting apicture taken for prom.
neutral: The friends standing next to each other might be co-workers, family, or even just two people that just met, so they aren't automatically men. Their formal wear could mean that they are going somewhere else, not just to prom. People can also have a picture taken without standing next to each other - they may be sitting down or waiting in line for the photographer.
