You are going to read an article about a woman pilot. Eight sentences have been removed from the article. Choose from the sentences A-1 the one which fits each gap (15-21). There is one extra sentence which you do not need to use.

15__ It ended only three days behind schedule when she landed her Piper Dakota at Birmingham in central England in May, five months later. 16__ This included storms and a cyclone in Fiji, a country in the South Pacific Ocean. Nor was the journey without incident for Polly, who only learned to fly at the age of forty-nine. One of the trip's most frightening moments came, on the same route where Amelia Earhart, the American pilot, went missing when she was attempting to fly around the world in 1937. 17__ In fact, she allowed herself to be photographed as she stood beside a Banyan tree, which Amelia Earhart had planted in 1935, before setting off for the 16-hour section of her flight from Hawaii to California. According to Polly all went well for the first part of her journey. 18__Then suddenly it started to get very bumpy. Checking the outside air temperature Polly discovered it was zero degrees. To her horror she found streams of ice- cold rain running back along the wings and starting to freeze. 19__ Though Polly immediately dropped her height to prevent the weight of ice pulling her plane into the ocean, there was more drama when the cabin suddenly went quiet. 20__ As a result the main tank had run dry an hour early, but fortunately the emergency tank went into action and she was able to land safely. The lonely hours spent flying were a great contrast to the warm welcome she received wherever she landed. 21__ The publicity she attracted also raised money for a charity which provides flying scholarships for disabled people.

A. Polly`s 46`000km record-breaking journey began in January
