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.

Question: "What are two ways we might suspect a tree has become dormant?"

Response: "Its leaves have changed color and it dies"

What if you could drain all of Earths oceans? What would it look like? You might be really surprised. You see that the surface has two main features. It has continents and ocean basins. Continents are large land areas. These are the areas that are mostly above sea level. Ocean basins extend from the edges of continents. They include the ocean floor and Earths deep ocean trenches. You will also notice the ocean floor is not flat. It too has many Continents are much older than ocean basins. Some rocks on the continents are billions of years old. Ocean basins may only be millions of years old. Because the continents are so old, a lot has happened to them! As we view the land around us, we see landforms. Landforms are physical features on Earths surface. These features change over time, but how? There are actually two types of forces at work.

Question: "What are the characteristics of the ocean floor?"

Response: "It is not flat, it has many continents that are much older than ocean basins. Some of these continents are billions of years old"

As for the Italians, we know that Paesiello, who was a famous intriguer against his musical rivals, was a devoted husband whose wife was an invalid and who died soon after her death. Cherubini married Mademoiselle Cecile Turette, when he was thirty-five, and the marriage was not a success. He left a son and two daughters. Spontini, one of whose best operas was based on the life of that much mis-married enthusiast for divorce, John Milton, took to wife a member of the Erard family. In the outer world Spontini was famous for his despotism, his jealousy, his bad temper, and his excessive vanity. None of these qualities as a rule add much to home comfort, and yet, it is said that he lived happily with his wife. We may feel sure that some of the bad light thrown on his character is due purely to the jealousy of rivals, when we consider his domestic content, his ardent interest in the welfare of Mozart's widow and children, and the great efforts he made to secure subscriptions for the widow's biography of Mozart.

Question: "Who were three Italians, whom this passage describes?"

Response: "Paesiello, Cherubini, and Spontini"

A:
yes
