premise: People at an event involving umbrellas embrace one another.
hypothesis: The people at the event are embracing each other
explanation_1: Only one group of people and one event are mentioned, so 'the' is appropriate in both cases; since they embrace, they are embracing; 'each other' is synonymous with 'one another'.
