Leo: Given the sentence "Several young people are standing around drinking beverages at some kind of outdoors gathering with food." is it true that "Young people are drinking underage."?

Just because young people are standing around drinking beverages outdoors doesn't mean they are drinking underage. They may be drinking Coke.
Thus, the answer is it is not possible to tell.
