A That was how Doug and Deborah's sister got to know each other.
B After the ceremony was over, all the guests were invited to a reception in the outdoor garden patio.
C Her parents were worried that they might get caught in peak-hour traffic along
the way and decided that it was better to be early than late. D They bought souvenirs from New York to all their relatives.
E She and her parents had to be in New York to do the final fittings of their dress­es and suits.
F She was a professional dancer and worked for a professional dance company in New York.
Deborah checked in her luggage two hours before the flight was scheduled to depart.
This was in line with standard airline regulations. She had arrived at the airport an
hour ago. (1)....... Thankfully, the roads to the airport were relatively clear.
Deborah and her parents were on their way to new York. Her sister had been work­ing there for the past four years. (2) ..... Her job required her to travel all around the United States to perform. It was during one of these trips three years ago that her sister met Doug.
Doug was an American accountant. He had gone with a friend to watch the dance performance. His friend was also an acquaintance of one of the other dancers in the company. (3) ..... Now, the two of them were getting married next month. That was why Deborah and her parents were going to New York.
Deborah was going to be one of the flower girls at her sister's wedding. (4) ..... They also had to be present for the wedding rehearsal. While they were there, they took the opportunity to do some sightseeing in New York. This was their first visit there. Debo­rah visited Times Square with all its bright lights and the majestic Statue of Liberty. She bought souvenirs for a few of her friends back in Australia.
Finally, the big day arrived. Everyone was giddy with excitement. Deborah's sister
was a nervous wreck. She was worried that she might forget something or that some­
thing might go wrong. They had to keep reassuring her that everything was fine. In the
end, the wedding ceremony proceeded without a hitch. It was a beautiful and touching
ceremony. (5)...... It was a splendid day and the food was delicious.
