Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Hope is a Symbolist oil painting by the English painter George Frederic Watts, who completed the first two versions in 1886. Radically different from previous treatments of the subject, it shows a lone blindfolded female figure sitting on a globe, playing a lyre that has only a single string remaining. The background is almost blank, its only visible feature a single star. Watts intentionally used symbolism not traditionally associated with hope to make the painting's meaning ambiguous. While his use of colour in Hope was greatly admired, at the time of its exhibition many critics disliked the painting. Hope proved popular with the Aesthetic Movement, who considered beauty the primary purpose of art and were unconcerned by the ambiguity of its message. Reproductions in platinotype, and later cheap carbon prints, soon began to be sold.
Although Watts received many offers to buy the painting, he had agreed to donate his most important works to the nation and felt it would be inappropriate not to include Hope. Consequently, later in 1886 Watts and his assistant Cecil Schott painted a second version. On its completion Watts sold the original and donated the copy to the South Kensington Museum (now the Victoria and Albert Museum); thus, this second version is better known than the original. He painted at least two further versions for private sale.
As cheap reproductions of Hope, and from 1908 high-quality prints, began to circulate in large quantities, it became a widely popular image. President Theodore Roosevelt displayed a copy at his Sagamore Hill home in New York; reproductions circulated worldwide; and a 1922 film depicted Watts's creation of the painting and an imagined story behind it. By this time Hope was coming to seem outdated and sentimental, and Watts was rapidly falling out of fashion. In 1938 the Tate Gallery ceased to keep their collection of Watts's works on permanent display.
Despite the decline in Watts's popularity, Hope remained influential. Martin Luther King Jr. based a 1959 sermon, now known as Shattered Dreams, on the theme of the painting, as did Jeremiah Wright in Chicago in 1990. Among the congregation for the latter was the young Barack Obama, who was deeply moved. Obama took "The Audacity of Hope" as the theme of his 2004 Democratic National Convention keynote address, and as the title of his 2006 book; he based his successful 2008 presidential campaign around the theme of "Hope".
What is the first name of the person who intentionally used symbolism not traditionally associated with hope to make the painting's meaning ambiguous?
