[EX Q]: Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right. <sep>Why do some plants go dormant in winter?<sep>Because it is dying
[EX A]: No

[EX Q]: Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video. <sep>What are some things density explains?<sep>It explains why some things float in or sink
[EX A]: Yes

[EX Q]: The Venetian artist Jacopo de' Barbari, whom Durer had met in Venice, visited Nuremberg in 1500, and Durer said that he learned much about the new developments in perspective, anatomy, and proportion from him. De' Barbari was unwilling to explain everything he knew, so Durer began his own studies, which would become a lifelong preoccupation. A series of extant drawings show Durer's experiments in human proportion, leading to the famous engraving of Adam and Eve (1504), which shows his subtlety while using the burin in the texturing of flesh surfaces. This is the only existing engraving signed with his full name. Durer made large numbers of preparatory drawings, especially for his paintings and engravings, and many survive, most famously the Betende Hande (English: Praying Hands, c. 1508 Albertina, Vienna), a study for an apostle in the Heller altarpiece. He also continued to make images in watercolour and bodycolour (usually combined), including a number of still lifes of meadow sections or animals, including his Young Hare (1502) and the Great Piece of Turf (1503, both also Albertina). <sep>Which named works were made by Durer in Albertina, Vienna?<sep>Meadow section
[EX A]:
No
