Read the following passage and choose the best answer to each question The Peales were a distinguished family of America artists. Charles Wilson is best remembered for his portraits of leading figures of the American revolution. He painted portraits of Franklin and Jefferson, and over a dozen of George Washington. His life size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat to the figures in the picture. Charles Wilson Peale gave up painting in this middle age and devoted his life to the Peale, Museum which he founded in Philadelphia. The word's first popular museum of art and natural science, it featured paintings by Peale family as well as displays of animals in their natural settings. Peale found the animals himself and devised a 'method of taxidermy to make the exhibits more lifelike. The museum's most popular display was the skeleton of a mastodon -a huge, extinct elephant - which Peale unearthed on a New York farm in 1801. Three of Peale's seventeen children were also famous artists, Raphaelle Peale often painted still life of flowers, fruit, and cheese. His works show the same luminosity arid attention to detail that the works of the Dutch masters show. In the late eighteenth century, however, portraiture was the rage, and so Raphaelle Peale found few buyers for his still life at the time. His brother Rembrandt studied under his father and painted portraits of many noted people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.
