Read the passage from A New Astronomy, by David Todd.From Polaris a line of small stars curves toward the handle of the Dipper, meeting the upper one of a pair of the third magnitude. This pair, with another farther on and parallel to it, form the 'Little Dipper,' Polaris being the end of its handle. The group is Ursa Minor. Opposite the handle of the great Dipper, and at about the same distance from Polaris, are five rather bright stars forming a flattened letter W. They are the principal stars of Cassiopeia.What strategy does the author use in his choice of language to convey his message?
