Input: (CNN) -- The photographer who took images of former Pakistani Prime Minister Benazir Bhutto moments before her assassination Thursday told CNN he was "surprised" to see her rise through the sunroof of her vehicle to wave to supporters after delivering her speech. Getty Images photographer John Moore captured Benazir Bhutto waving, moments before he heard gunshots. "I ran up, got as close as I got, made a few pictures of her waving to the crowd," Getty Images senior staff photographer John Moore told CNN's online streaming news service, CNN.com Live, in a phone interview Thursday from Islamabad, Pakistan. "And then suddenly, there were a few gunshots that rang out, and she went down, she went down through the sunroof," he said. "And just at that moment I raised my camera up and the blast happened. ... And then, of course, there was chaos." Watch Moore describe Bhutto's final moments " Moore said he was about 20 yards away from Bhutto's vehicle when he took his photographs. Bhutto was rushed to Rawalpindi General Hospital, where she was pronounced dead. Moore said he had been following Bhutto's story since her return to Pakistan in October. He was present October 19 when a terror attack targeting her motorcade in Karachi killed 136 people. In the aftermath of that attack, "The rallies had been very small," because of high security, Moore said. However, the Rawalpindi rally was announced beforehand, he observed. "Whoever planned this attack -- they had time on their hands to plan everything properly, and you saw the results today," he said. Between 5,000 and 8,000 were at the Rawalpindi rally, which was held at a parkground, he said. "We [the news media] all expected it to be filled ... but there were less people there than most of us expected to see," he said. "When I talked with a number of people, they said that people were just afraid to come out, for the simple reason that they all remembered what happened in Karachi." Moore said he himself expected there could be another attack following the Karachi massacre. He said he stayed away from gates at the Rawalpindi parkground, where police were searching people, because he suspected that's where a bomb would go off.

Does the response "He said he stayed away from gates" correctly answer the question "When Moore was expecting an attack, what did he do in response to this fear?"?

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 it eliminates solid food waste" correctly answer the question "What two things does the digestion system do for the body?"?

Input: When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though.

Does the response "Bacteria" correctly answer the question "What do humans have that plants don't have?"?

Input: "What goes up must come down." You have probably heard that statement before. At one time this statement was true, but no longer. Since the 1960s, we have sent many spacecraft into space. Some are still traveling away from Earth. So it is possible to overcome gravity. Do you need a giant rocket to overcome gravity? No, you actually overcome gravity every day. Think about when you climb a set of stairs. When you do, you are overcoming gravity. What if you jump on a trampoline? You are overcoming gravity for a few seconds. Everyone can overcome gravity. You just need to apply a force larger than gravity. Think about that the next time you jump into the air. You are overcoming gravity for a brief second. Enjoy it while it lasts. Eventually, gravity will win the battle.

Does the response "True" correctly answer the question "Are you overcoming gravity when you climb a set of stairs?"?
