Question:
Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age. After reading the above, is "To create chemical energy" the correct answer to the question "How are index fossils used?"?

Answer:
no

Question:
Elettra stuck the little slip of paper, on which the recipe was written, into her shabby pocket-book without looking at it. She could read and write fairly well, and had been used to helping her husband the under-steward with his accounts at Muro, but even if she had looked at the recipe she would have understood nothing of the doctor's hieroglyphics and abbreviated Latin words. The prescription was for a preparation of arsenic, which Matilde had formerly taken for some time. The chemist would not make any difficulty about preparing twenty doses of it for the Countess Macomer, though the whole quantity of arsenic contained in so many would probably be sufficient to kill one not accustomed to the medicine, if taken all at once. But though Matilde was so anxious to have the stuff before luncheon, she had a number of doses of it put away in a drawer, which she took out and counted, after Elettra had gone. She opened one of the little folded papers and looked at the fine white powder it contained, took a little on the end of her finger and tasted it. Then, from the same drawer, she took a package done up in coarser paper, and opened it likewise, looked at it, smelt it, and touched it with the tip of her tongue very cautiously indeed. It was white, too, but coarser than the medicine. She was very careful in tasting it, and she immediately rinsed her mouth with water, before she tied up the package again, shut the drawer, and put the key into her pocket. After reading the above, is "Rinsed her mouth with water" the correct answer to the question "After touching the tip of her tongue to the arsenic, what did Matilde do?"?

Answer:
yes

Question:
Although Bin Laden, Atef, and KSM initially contemplated using established al Qaeda members to execute the planes operation, the late 1999 arrival in Kandahar of four aspiring jihadists from Germany suddenly presented a more attractive alternative. The Hamburg group shared the anti-U.S. fervor of the other candidates for the operation, but added the enormous advantages of fluency in English and familiarity with life in the West, based on years that each member of the group had spent living in Germany. Not surprisingly, Mohamed Atta, Ramzi Binalshibh, Marwan al Shehhi, and Ziad Jarrah would all become key players in the 9/11 conspiracy. Mohamed Atta was born on September 1, 1968, in Kafr el Sheikh, Egypt, to a middle-class family headed by his father, an attorney. After graduating from Cairo University with a degree in architectural engineering in 1990, Atta worked as an urban planner in Cairo for a couple of years. In the fall of 1991, he asked a German family he had met in Cairo to help him continue his education in Germany. They suggested he come to Hamburg and invited him to live with them there, at least initially. After completing a course in German, Atta traveled to Germany for the first time in July 1992. He resided briefly in Stuttgart and then, in the fall of 1992, moved to Hamburg to live with his host family. After enrolling at the University of Hamburg, he promptly transferred into the city engineering and planning course at the Technical University of Hamburg-Harburg, where he would remain registered as a student until the fall of 1999. He appears to have applied himself fairly seriously to his studies (at least in comparison to his jihadist friends) and actually received his degree shortly before traveling to Afghanistan. In school, Atta came across as very intelligent and reasonably pleasant, with an excellent command of the German language. When Atta arrived in Germany, he appeared religious, but not fanatically so. This would change, especially as his tendency to assert leadership became increasingly pronounced. According to Binalshibh, as early as 1995 Atta sought to organize a Muslim student association in Hamburg. In the fall of 1997, he joined a working group at the Quds mosque in Hamburg, a group designed to bridge the gap between Muslims and Christians. Atta proved a poor bridge, however, because of his abrasive and increasingly dogmatic personality. But among those who shared his beliefs, Atta stood out as a decisionmaker. After reading the above, is "Mohamed Atta, Ramzi Binalshibh, Marwan al Shehhi, and Ziad Jarrah" the correct answer to the question "Who were the jihadists that met in Germany and determined that fluency in English would better their odds in a successful attack on the US?"?

Answer:
yes

Question:
Hannah Harvey was a ten year old that had many friends in school. She lived in New York and enjoyed doing gymnastics and playing soccer. One day, Hannah came home from school and her parents greeted her. She knew that something was different by the expressions on their faces. Even Jackson, Hannah's dog, was acting different. Hannah asked why everyone was being so strange. Hannah's father, who was known as Pop, explained to Hannah that his job was forcing him to move. Hannah did not seem to think this was too big of a deal. Then, Hannah's mother explained that they were moving to Kenya. Kenya, she explained, was a place in Africa and life would be very different there. As Hannah began to cry thinking about all of her friends at home, Hannah's mother calmed her with a gentle touch. Jackson began howling as Hannah cried, but was also calmed by Hannah's mother. Hannah spent the next two weeks visiting her friends and saying her goodbyes. She did not know the next time she would be home. She cried very hard when she said goodbye to her best friend, Susan. Susan did not quite understand where Kenya was, but promised to visit Hannah. The next day, Hannah boarded a plane with her family. At first, they thought that Jackson could not come with them. However, Hannah worked hard and helped make sure that he had all of his shots so that he could come. After he had them all, the airport said it was OK for Jackson to come! The Harvey family left and off they went across the ocean to begin their new life in Kenya. After reading the above, is "Hannah is 10" the correct answer to the question "How old is Hannah when she finds out that she is moving from New York to Kenya?"?

Answer:
no
