"From 8:30 pm to 9:30 pm on March 28,please turn off your lights to save energy and protect our Mother Earth,"the letters said.

Mona Lisa, the mysterious woman in Leonardo da Vinci's 16th century masterpiece, had just given birth to her second son when she sat for the painting, a French art expert said on Tuesday. The discovery was made by a team of Canadian scientists who used special infrared and three-dimensional technology to study the paint layers on the work, which now sits in the Louvre museum in Paris. Bruno Mottin of the French Museums' Center for Research and Restoration said that on very close examination of the painting it became clear that the Mona Lisa's dress was covered in a thin transparent gauze veil. "This type of gauze dress was typical of the kind worn in early 16th century Italy by women who were pregnant or who had just given birth. This is something that had never been seen up to now because the painting was always judged to be dark and difficult to examine," he told a news conference. "We can now say that this painting by Leonardo da Vinci was painted in memory of the birth of the second son of Mona Lisa, which helps us to date it more precisely to around 1503."The young woman with the ambiguous half smile has been identified as Lisa Gherardini, wife of Florentine merchant Francesco de Giocondo. She had five children. "People always wrote that Mona Lisa had allowed her hair to hang freely over her shoulders. This greatly surprised historians because letting your hair hang freely during the Renaissance was typical of young girls and women of poor virtue ," he said. The team had hoped to discover more details about Leonardo's painting techniques, which the artist used to create a hazy effect. But scientist John Taylor said the team had been disappointed by the lack of brush stroke detail on the painting. According to the latest research, Mona Lisa was _ . A) a woman of poor virtue B) da Vinci's second wife C) a woman who was pregnant D) the wife of Florentine merchant

Ques:Robert Todd Duncan was born in 1903 in the southern city of Danville,Kentucky. His mother was his first music teacher. As a young man,he continued his music study in Indianapolis,Indiana. In 1930,he completed more musical education at Columbia University in New York City. Then he moved to Washington. For fifteen years, he taught music at Howard University in Washington. At that time, not many black musicians were known for writing or performing classical music. Teaching at Howard gave Duncan the chance to share his knowledge of classical European music with a mainly black student population. He taught special ways to present the music.These special ways became known as the Duncan Technique. Besides teaching,Duncan sang in several operas with performers who were all black. But it seemed that he always would be known mainly as a concert artist. However,his life took a different turn in the middle 1930s. At that time, the famous American music writer George Gershwin was looking for someone to play a leading part in his new work Porgy and Bess. The music critic of the New York Times newspaper suggested Todd Duncan. Duncan had almost decided not to try for the part as he knew it would not be easy to get it. But he changed his mind. He sang a piece from an Italian opera for Gershwin. He had sung only a few minutes when Gershwin offered him the part. He became famous because of the part in Porgy and Bess. Todd Duncan gained fame as an opera singer and concert artist. But his greatest love in music was teaching. When he stopped teaching at Howard,he continued giving singing lessons in his Washington home until the week before his death. We can infer that Robert Todd Duncan didn't at first want to try for the part mainly because _ . A) he was too busy to do it B) he was not interested in it C) he was not confident enough D) he didn't want to become famous
