Read the following article and select the best answer. Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make. Question: What Sir Francis Bacon said was right, but people didn't believe him until _ . - late in the 19th century - early in the 20th century - three years ago - late in the 20th century
late in the 20th century

Read the following article and select the best answer. Article: From early times, man has been interested in art. People have often worked together to collect and save the world's art treasures. Fine art treasures from many countries are kept in an art museum called the Louvre in Paris, France. The works of art have been collected by the people of France over many centuries. It is the biggest art museum in the world. The Louvre has not always been a museum. The first building was a fort. In 1190, it was the king's castle with high walls and a round tower, which had a river around it to keep out the enemies. Over the years, the number of buildings around the castle grew. By 1350, the castle no longer needed a fort. The Louvre became a palace home for French kings and queens. During times of peace, new treasures were brought in. During the days of war, many treasures were stolen, and the buildings were damaged. When Francis I became king of France in 1515, he brought in many artists from other countries. One of the artists was Lenardo da Vinci from Italy. Da Vinci's "Mona Lisa" is the best known painting in the museum today. In 1793, the Louvre became a public museum. It is a place where art treasures are kept for everyone to enjoy. Every year millions of people from all over the world come to the Louvre to see the masterpieces. Question: Most of works of art in the Louvre have been collected probably by _ . - the French people - Francis I - Leonardo da Vinci - people of the world
