Input: A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge.

Does the response "Water in the soil" correctly answer the question "What makes the floodplains good for growing plants?"?

Input: 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.

Does the response "No, they fall off in the autumn only" correctly answer the question "Do some plants' leaves fall off in the winter months?"?

Input: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

Does the response "Magnetic field" correctly answer the question "What do the structures in a bird's eye allow them to do?"?

Input: One day a young boy went to visit a toy store. In the toy store the young boy found many fun toys. One toy that the boy really liked was a small blue toy truck. The small blue toy truck was a lot of fun to play with, and made a lot of funny noises. The young boy played with the toy truck for a long time, and then another little boy showed up and began to play with a little red car. The two boys ended up becoming friends and played with the toys for a long time. They ended up becoming good friends and had many play dates together over the months ahead. On one play date the two boys built a large tree house and called it the tree castle. They played for hours in the tree castle and always found something fun to do when they played together. They were glad that they met in the toy store and became life-long friends.

Does the response "Another little boy" correctly answer the question "Who was playing with the toy that made a lot of funny noises?"?
