The dreaming astronomer
There lived an astronomer who was very much interested in his observations. He 7 2. used to look up at the sky at night and to observe the stars. Once, as he was walking and looking up at the stars at the same time, his leg slipped and he [8 fell into a canal. He started shouting. A passer-by, who 9 3. heard his shouts, helped him out of the canal and asked, 'How did you fall into this canal? The astronomer replied, was so busy [10] 1. with my observations that I did not notice it. The passer-by asked, 'How [11] 3. did you expect to discover things when you don't take notice of things under your nose?' The astronomer walked away with a sad face.
