Example Input: You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air. <sep>What happens when less heat reaches the surface of your skin?<sep>Cools the body
Example Output: No

Example Input:  Bin Laden began delivering diatribes against the United States before he left Saudi Arabia. He continued to do so after he arrived in Sudan. In early 1992, the al Qaeda leadership issued a fatwa calling for jihad against the Western "occupation" of Islamic lands. Specifically singling out U.S. forces for attack, the language resembled that which would appear in  Bin Laden's public fatwa in August 1996. In ensuing weeks,  Bin Laden delivered an often-repeated lecture on the need to cut off "the head of the snake." By this time,  Bin Laden was well-known and a senior figure among Islamist extremists, especially those in Egypt, the Arabian Peninsula, and the Afghanistan-Pakistan border region. Still, he was just one among many diverse terrorist barons. Some of  Bin Laden's close comrades were more peers than subordinates. For example, Usama Asmurai, also known as Wali Khan, worked with  Bin Laden in the early 1980s and helped him in the Philippines and in Tajikistan. The Egyptian spiritual guide based in New Jersey, the Blind Sheikh, whom  Bin Laden admired, was also in the network. Among sympathetic peers in Afghanistan were a few of the warlords still fighting for power and Abu Zubaydah, who helped operate a popular terrorist training camp near the border with Pakistan. There were also rootless but experienced operatives, such as Ramzi Yousef and Khalid Sheikh Mohammed, who-though not necessarily formal members of someone else's organization-were traveling around the world and joining in projects that were supported by or linked to  Bin Laden, the Blind Sheikh, or their associates. In now analyzing the terrorist programs carried out by members of this network, it would be misleading to apply the label "al Qaeda operations" too often in these early years. Yet it would also be misleading to ignore the significance of these connections. And in this network,  Bin Laden's agenda stood out. While his allied Islamist groups were focused on local battles, such as those in Egypt, Algeria, Bosnia, or Chechnya,  Bin Laden concentrated on attacking the "far enemy"-the United States. After U.S. troops deployed to Somalia in late 1992, al Qaeda leaders formulated a fatwa demanding their eviction. In December, bombs exploded at two hotels in Aden where U.S. troops routinely stopped en route to Somalia, killing two, but no Americans. <sep>What was the names and locations of two peers of bin Ladin?<sep>Blind Sheik - New Jersey
Example Output: Yes

Example Input: The cute red ball rolled over to the blue ball and said hello. The blue ball was scared and went to cry to the green ball. The green ball laughed at the blue ball. Then the green ball told the orange ball that blue ball was stupid. Most felt this was not good to do and so they punished the green ball by taking away all his air. From that day on everyone saw the air-less green ball and knew that they could not do or say any bad things. This is how the trouble started. The purple ball used the fear of everyone to become the leader that they all feared. The purple ball was mean to everyone. Until one day the red ball spoke up and got all the other colored balls together and they took the air from the purple ball and put it in the green ball. Sadly, the green ball had been without air for too long and was dead. <sep>Why could the balls not say bad things?<sep>They took away the green balls air
Example Output:
No
