According to Omar, what is the second best feature of his new school?

The selection of the rec room as the second best feature of Omar's new school likely highlights its importance as a social and recreational space where students can unwind and interact with peers. A rec room often serves as a hub for various activities, fostering a sense of community among students. It can be a place for games, relaxation, and creativity, contributing to a well-rounded school experience.

In contrast, while features like the cafeteria, library, and playground may also offer valuable resources and experiences, they may not provide the same level of social interaction or recreational opportunities that the rec room does. For instance, the cafeteria is primarily focused on dining, the library is mainly intended for study and research, and the playground is primarily suited for physical activity and playtime. Thus, the rec room stands out as a space that emphasizes student engagement and enjoyment, making it a compelling choice for Omar when considering the highlights of his new school.
