First and Second Endings are used when part
of the previous music is repeated but has a different ending.
At the finish of the first ending (the measures under the bracket
with a 1) there is a repeat sign
at which you will return to either the beginning of the piece
or to a repeat sign that faces the other direction .
The music is then played again, skipping the first ending and
playing the second ending instead.
