Suppose The Concert<br>A famous band performed a sold-out concert at the arena. Fans lined up for hours to get the best seats, and some even camped out overnight. The band played all their hit songs, and the crowd sang along enthusiastically. After the concert, fans lingered outside, hoping to catch a glimpse of the band members leaving the venue.
Can we infer that "The concert was held outdoors."? Yes, no, or maybe?
