this was a multiple choice question on my test and the answer was because the particles are attracted to each other...why is this the answer?

Real gases unlike Ideal gases have a volume and an attraction between the particles. These intermolecular forces play a great role in determining the properties of the gas. For example, if water vapor is cooled below 100 degrees Celsius at standard atmospheric pressure, it condenses to a liquid.

Real gases consists of particles which are loosely arranged among them. When we are to condensed and solidified the gas, we cool the gas down.
Cooling means reducing the energy of the particles.
Liquid particles are arrange more loosely than particles of gases.
When we lower the energy of liquid particle, they become less in energy and do not move freely , and so they are solidified. the particles of solid only vibrates in their place.

An ideal gas would never liquefy, because an ideal gas has absolutely no attractive forces.
The fact that gases do liquefy, when cooled sufficiently, shows that attractive forces do exist between molecules.
