Final answer:
Proximity and similarity are important factors in making people attracted to each other.
Step-by-step explanation:
The most influential factor in determining with whom we become friends and form romantic relationships is proximity. People are more likely to be attracted to individuals they have regular contact with, such as those who live in the same dorm, apartment building, or neighborhood. Proximity makes it easier to get to know someone and increases the opportunities for interaction.
Another important factor is similarity. We are more likely to form relationships with people who share a similar background, attitudes, and lifestyle. Having things in common makes it easier to connect and spend time together.
In conclusion, proximity and similarity play significant roles in making people attracted to each other.
