Greg is having trouble concentrating for several reasons. First, his roommate watching TV in the other room can be distracting because the noise and visuals can divert his attention away from his studies. The constant noise from the radio playing in Greg's bedroom is likely adding to the distractions. Additionally, the frequent ringing of the phone can disrupt his focus as he may feel compelled to answer it or wonder who is calling. All these external stimuli are creating a noisy and disruptive environment, making it challenging for Greg to concentrate on his studies.
