"The girls drink."
However, it lacks context. To understand the intended meaning, we need to know:
* Who are "the girls"? Are they friends, sisters, classmates, or something else?
* What are they drinking? Water, wine, juice?
* What is the situation? Are they at a party, a dinner, or just hanging out?
Without more information, it's difficult to interpret the phrase accurately.
