Note that a difference in cultures doesn't necessarily mean different countries or languages; the difference between living in a large city and living in a small town is an example of cultural differences. Different types of jobs (medical careers, criminal justice careers, information technology careers) have their own cultures with unique jargon. Married or single - those are two different cultures. Different age groups are more accustomed to the "culture" of their own generation, so today's children are in a different culture than today's adults.
A) You may have lived with a culturally different roommate in school or the military, or maybe you had a job where you either worked with someone from a different culture, or the customers were of various cultures. Describe an example from your own life experience when you benefited from an opportunity to learn something about a different culture; it could be a new holiday tradition, a new religious belief or custom, or a new delicacy that you only discovered because of your relationship with that person.
