Q: Paragraph- Sent 1: Zakariya Essabar, a Moroccan citizen, moved to Germany in February 1997 and to Hamburg in 1998, where he studied medical technology.
Sent 2: Soon after moving to Hamburg, Essabar met Binalshibh and the others through a Turkish mosque.
Sent 3: Essabar turned extremist fairly suddenly, probably in 1999, and reportedly pressured one acquaintance with physical force to become more religious, grow a beard, and compel his wife to convert to Islam.
Sent 4: Essabar's parents were said to have made repeated but unsuccessful efforts to sway him from this lifestyle.
Sent 5: Shortly before the 9/11 attacks, he would travel to Afghanistan to communicate the date for the attacks to the al Qaeda leadership.
Sent 6: Mounir el Motassadeq, another Moroccan, came to Germany in 1993, moving to Hamburg two years later to study electrical engineering at theTechnical University.
Sent 7: A witness has recalled Motassadeq saying that he would kill his entire family if his religious beliefs demanded it.
Sent 8: One of Motassadeq's roommates recalls him referring to Hitler as a "good man" and organizing film sessions that included speeches by Bin Laden.
Sent 9: Motassadeq would help conceal the Hamburg group's trip to Afghanistan in late 1999.
Sent 10: Abdelghani Mzoudi, also a Moroccan, arrived in Germany in the summer of 1993, after completing university courses in physics and chemistry.
Sent 11: Mzoudi studied in Dortmund, Bochum, and Muenster before moving to Hamburg in 1995.
Sent 12: Mzoudi described himself as a weak Muslim when he was home in Morocco, but much more devout when he was back in Hamburg.
Sent 13: In April 1996, Mzoudi and Motassadeq witnessed the execution of Atta's will.
Sent 14: During the course of 1999, Atta and his group became ever more extreme and secretive, speaking only in Arabic to conceal the content of their conversations.
Sent 15: 87 When the four core members of the Hamburg cell left Germany to journey to Afghanistan late that year, it seems unlikely that they already knew about the planes operation; no evidence connects them to al Qaeda before that time.
Sent 16: Witnesses have attested, however, that their pronouncements reflected ample predisposition toward taking some action against the United States.
Sent 17: In short, they fit the bill for Bin Laden, Atef, and KSM.
Sent 18: Going to Afghanistan The available evidence indicates that in 1999, Atta, Binalshibh, Shehhi, and Jarrah decided to fight in Chechnya against the Russians.
Question: In what country did Essabar and Binalshibh meet?.

A: Germany.

Q: Paragraph- Sent 1: Earths magnetic field helps protect Earth and its organisms.
Sent 2: It protects us from harmful particles given off by the sun.
Sent 3: Most of the particles are attracted to the north and south magnetic poles.
Sent 4: This is where Earths magnetic field is strongest.
Sent 5: This is also where relatively few organisms live.
Sent 6: Another benefit of Earths magnetic field is its use for navigation.
Sent 7: People use compasses to detect Earths magnetic north pole.
Sent 8: Knowing this helps them tell direction.
Sent 9: Many animals have natural 'compasses' that work just as well.
Sent 10: Birds like the garden warbler in Figure 1.36 use Earths magnetic field.
Sent 11: They use it to guide their annual migrations.
Sent 12: Recent research suggests that warblers and other migrating birds have structures in their eyes.
Sent 13: These structures let them see Earths magnetic field as a visual pattern.
Question: Where is the structure located, that warblers use to detect the magnetic fields of Earth?.

A: In their Eyes.

Q: Paragraph- Sent 1: Water flowing over Earths surface or underground causes erosion and deposition.
Sent 2: Water flowing over a steeper slope moves faster and causes more erosion.
Sent 3: How water transports particles depends on their size.
Sent 4: When water slows down, it starts depositing sediment.
Sent 5: This process starts with the largest particles first.
Sent 6: Runoff erodes the land after a heavy rain.
Sent 7: It picks up sediment.
Sent 8: Runoff carries most of the sediment to bodies of water.
Sent 9: Mountain streams erode narrow, V-shaped valleys and waterfalls.
Sent 10: Erosion and deposition by slow-flowing rivers create broad floodplains and meanders.
Sent 11: Deposition by streams and rivers may form alluvial fans and deltas.
Sent 12: Floodwaters may deposit natural levees.
Sent 13: Erosion and deposition by groundwater can form caves and sinkholes.
Sent 14: Stalactites and stalagmites are mineral deposits.
Sent 15: They build up in caves as water continues to drip.
Question: What liquid causes erosion?.

A:
Heavy rain.
