Input: Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push.
"What does a strong push or a weak push have to do with force?" is "It explains the size of the force"?
Output: yes
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.
"When Moore was expecting an attack, what did he do in response to this fear?" is "Were searching people"?

Input: Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.
"What is located below the lungs?" is "Diaphragm"?

yes
