Final answer:
Romeo is drawn to Juliet because he finds her exceptionally beautiful upon first sight, which leads to their eventual tragic romance.
Step-by-step explanation:
Romeo is initially drawn to Juliet primarily because he thinks she is beautiful. His infatuation begins the moment he sees her at the Capulet party, where he is struck by her physical appearance, which outshines everyone else in the room. This is evident in his words upon first noticing her, describing Juliet's beauty as teaching the torches to burn bright. While Romeo's attraction to Juliet does deepen as they interact, it is her beauty that captures his attention initially, leading to the fateful events that unfold in Shakespeare's tragedy.
