Question:
Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better. After reading the above, is "To make our lives better" the correct answer to the question "Why do we use radio waves, microwaves, and X rays?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
Crusaders, Mamelukes, and Turks: The Crusaders established a feudal Christian state with Godfrey at its head. They built many impressive churches during the term of the first Latin Kingdom of Jerusalem, but in 1187 they were driven out by Muslim forces under the great warrior Saladin. During the Sixth Crusade (1228 1229), the Holy Roman Emperor Frederick II managed to secure Jerusalem for the Christians by negotiation. The Christians, however, could not hold the city. After they lost Jerusalem, a Mongol invasion swept through, and in 1244 the Mameluke dynasty of Egypt took control, ruling Jerusalem for the next 250 years. The city struggled to rebuild from Crusader wars and invasions. Much of the best Islamic architecture in the city was constructed in the Mameluke era, but the past thousand years had taken their toll: Jerusalem was unable to regain the prosperity it had enjoyed in earlier times. In the early 16th century, the Ottoman Turkish Empire was advancing through the Middle East. Jerusalem fell to the Ottomans in 1517, remaining under their control for 400 years. Suleiman the Magnificent rebuilt the walls and gates in the form they retain to this day. Fountains, inns, religious schools, and barracks were constructed. But when Suleiman died, his empire, including Jerusalem, began a long period of decline. The Holy City remained a backwater until the 19th century, when renewed interest among Christian pilgrims made it the destination of thousands of travelers each year. After reading the above, is "The Ottoman Empire took control of Jerusalem" the correct answer to the question "What happened during the Sixth Crusade with the Christians?"? OPTIONS:
- no
- yes

Answer:
no

Question:
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. After reading the above, is "The large intestine" the correct answer to the question "Where does the absorption part of digestion occur?"? OPTIONS:
- no
- yes

Answer:
no

Question:
Not until 1998 did al Qaeda undertake a major terrorist operation of its own, in large part because Bin Laden lost his base in Sudan. Ever since the Islamist regime came to power in Khartoum, the United States and other Western governments had pressed it to stop providing a haven for terrorist organizations. Other governments in the region, such as those of Egypt, Syria, Jordan, and even Libya, which were targets of some of these groups, added their own pressure. At the same time, the Sudanese regime began to change. Though Turabi had been its inspirational leader, General Omar al Bashir, president since 1989, had never been entirely under his thumb. Thus as outside pressures mounted, Bashir's supporters began to displace those of Turabi. The attempted assassination in Ethiopia of Egyptian President Hosni Mubarak in June 1995 appears to have been a tipping point. The would-be killers, who came from the Egyptian Islamic Group, had been sheltered in Sudan and helped by Bin Laden. When the Sudanese refused to hand over three individuals identified as involved in the assassination plot, the UN Security Council passed a resolution criticizing their inaction and eventually sanctioned Khartoum in April 1996. A clear signal to Bin Laden that his days in Sudan were numbered came when the government advised him that it intended to yield to Libya's demands to stop giving sanctuary to its enemies. Bin Laden had to tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave the country. Outraged, several Libyan members of al Qaeda and the Islamic Army Shura renounced all connections with him. Bin Laden also began to have serious money problems. International pressure on Sudan, together with strains in the world economy, hurt Sudan's currency. Some of Bin Laden's companies ran short of funds. As Sudanese authorities became less obliging, normal costs of doing business increased. Saudi pressures on the Bin Laden family also probably took some toll. In any case, Bin Laden found it necessary both to cut back his spending and to control his outlays more closely. After reading the above, is "Because bin ladin had begun to have money problems" the correct answer to the question "Why did Bin Laden tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave Sudan?"? OPTIONS:
- no
- yes

Answer:
no
