Input: Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate.

Does the response "Fossils of plants and animals have been found, when there are no plants now" correctly answer the question "What Is the evidence that temperature used to be warmer in Antarctica?"?

Input: Johnnie had a set of small volumes of English verse, extensively annotated by his own hand, which Stoddard had brought to her early in their acquaintance, leaving it with her more as a gift than as a loan. She kept these little books after all the others had gone back. She had read and reread them--cullings from Chaucer, from Spenser, from the Elizabethan lyrists, the border balladry, fierce, tender, oh, so human--till she knew pages of them by heart, and their vocabulary influenced her own, their imagery tinged all her leisure thoughts. It seemed to her, whenever she debated returning them, that she could not bear it. She would get them out and sit with one of them open in her hands, not reading, but staring at the pages with unseeing eyes, passing her fingers over it, as one strokes a beloved hand, or turning through each book only to find the pencilled words in the margins. She would be giving up part of herself when she took these back. Yet it had to be done, and one miserable morning she made them all into a neat package, intending to carry them to the mill and place them on Stoddard's desk thus early, when nobody would be in the office. Then the children came in; Deanie was half sick; and in the distress of getting the ailing child comfortably into her own bed, Johnnie forgot the books. Taking them in at noon, she met Stoddard himself.

Does the response "She knew them by heart" correctly answer the question "Why could Johnnie not bear to return the books?"?

Input: 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.

Does the response "Ocean floor" correctly answer the question "What are continents?"?

Input: The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste.

Does the response "It turns food into nutrients and processes waste" correctly answer the question "What two things does the digestion system do for the body?"?
