Answer:
Race is often determined based on skin color only.
Step-by-step explanation:
Many people assume race can be determined based on skin color only. This is why a dark-skinned person is usually associated with somebody coming from the Middle East even if he or she is not. The reason for this assumption is that the skin is the largest organ and it is very salient.
Race is often very difficult to determine as many people are of mixed race. Making subjective assumptions about race can be dangerous and lead to misunderstandings. Many stereotypes and cultural biases were established in the first place because of peoples' misunderstanding of race and differences in cultural and social behaviors.
