Final answer:
A teenager might develop a crush due to a variety of factors including physical appearance, shared hobbies, peer pressure, and emotional connection, with an emotional connection being a key factor emphasized in the text.
Step-by-step explanation:
According to the text, a teenager may be drawn to a crush for a variety of reasons. Physical appearance often plays a significant role during this period of psychosocial changes due to the increased awareness of sexuality and body image that occurs with sexual maturation.
Teenagers also care more about their appearance and what they wear, seeking acceptance from their peers, which could influence their attraction to someone they consider physically appealing. Shared hobbies and interests can also create a foundation for a crush, as adolescents spend much of their time with peers and may develop romantic feelings toward someone with similar interests.
Peer pressure can sometimes contribute to feelings of attraction, especially if being in a relationship is considered a norm within the social group. However, the text most strongly suggests that an emotional connection is an essential component in the formation of these early romantic relationships, where adolescents are starting to establish their sense of identity and become more emotionally separated from their parents.
