Usually people do the five daily prayers in their homes or places of work with no imam around. They might go to a mosque once a week on Friday and hear an imam lead the prayer, and yes, the imam could decide to recite sura al-Baqarah (if the imam doesn’t mind trying the patience and stamina of the congregation, who would have to stand in prayer for an hour while the imam finishes reciting it), but that would be unusual. And even if that did happen, it’s not happening five times a day.
It’s more likely that Muslims would hear sura al-Baqarah once a year, during Ramadan, when the entire Quran is read over 30 nights.
