Final answer:
A cultural factor that can affect international business is the predominant religion prohibiting the use of alcohol in food products.
Step-by-step explanation:
One example of a cultural factor that can affect international business is the predominant religion prohibiting the use of alcohol in food products. This cultural norm may impact businesses that produce and sell food and beverages, as they would need to adapt their products to comply with religious beliefs. For instance, if a country's predominant religion prohibits alcohol consumption, a business that manufactures and sells alcoholic beverages would need to modify its products or find alternative markets where this cultural factor is not present.
