Input: 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.

Input: If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force. Mass and weight are closely related. However, the weight of an object can change if the force of gravity changes. On Earth, the force of gravity is the same everywhere. So how does the force of gravity change? It doesnt if you stay on Earth. What if we travel to another planet or moon in our solar system? Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure. They were the first humans to walk on the moon. An astronaut weighs less on the moon than he would on Earth. This is because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon. If his mass on Earth was 80 kg, what would his mass have been on the moon? [Figure 3]

Does the response "Because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change" correctly answer the question "Why did Edwin E. Aldrin Jr. and Neil Armstrong weigh less on the moon?"?

Fossils may form in other ways. Fossils can be preserved almost completely. In this process, the organism doesnt change much. As seen below, tree sap may cover an organism. With time, the sap hardens. It turns to into amber. The original organism is preserved. This is very exciting for scientists. They are able to study the DNA of the organism that no longer lives on Earth. Some animals have been found frozen in ice. Others have been found in tar pits after falling in. Molds and casts are another way organisms can be fossilized. Have you ever walked in soft mud and left footprints? Once in a while, these traces of organisms can be preserved. In this case, nothing is left of the organism. A mold is an imprint of an organism that is preserved in rock. The organisms remains break down completely. There is nothing left of the original plant and animal.

Question: "Why is amber so exciting for scientists?"

OPTIONS:
- no
- yes

Answer: "It looks beautiful"

Response: no

Search "Emiliano Malaquez" and you'll find he's a master of the "captured moment" school of sculpture. Even The Terran Times has only praise for his work. To compare his pieces to those of others is to compare mannequins to living models. He accents the illusion of reality --I paraphrase his entry in La Enciclopedia Humanica --by doing life-size scenes in "The full round," never the easier frontal or three-quarters view. Moreover, he never did portraits of famous people; his works were therefore the reality and could never be compared to it. As is typical of his school, his pieces are sealed in stopboxes. The shimmer of light on their surfaces always reminds us that we're looking at an instant snatched from under the hooves of time. They say the cubes will outlast planets and suns, that when the universe dies, the works of Malaquez and his followers will be the last things seen in the final wink of God's eye. Yes, Self, I am also bothered that this observation ignores half-eaten cheese sandwiches, incomplete insect collections, and locks of infants' hair, forgotten in closets, basements, and warehouses. You see the inspiration for my latest play, "Captured Moments." The mindwipe will take its creation from my future self --but time too often does that without aid. The play's second act concludes with the last fight between Tasha and me. I have disguised us in the play, and deleted one brief melodramatic interchange. Now I will mention it, in case I/You decide to restore it. Shortly before she left, Tasha said, "You steal from life for art, Bernardo. You'll impoverish yourself." I only snarled at her and -- My story leaps ahead of itself. Let me retreat and retrench: One night during N'apulco's mild winter, Tasha returned to The Flamingo, saying, "Nardo! Nardo! Guess what?"

Question: "Is Emiliano Malaquez's work abstract?"

Response: "He accents the illusion of reality and as such are abstract"

Problem: Tropical climates are found around the equator. These climates have warm temperatures year round. Tropical climates may be very wet or wet and dry. Tropical wet climates occur at or very near the equator. They have high rainfall year round. Tropical rainforests grow in this type of climate. Tropical wet and dry climates also occur near the equator. They receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season. The main plants are grasses. Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier. Deserts can get less than 25 centimeters of rain per year. Thats less than 10 inches per year. How much rain do you get at your house?

Question: "What are two factors contributing to the dryness of deserts?"

Answer: "They have high rates of evaporation"
