Q: After what seemed an eternity to Tibo, they arrived at the mouth of a cave between two rocky hills. The opening was low and narrow. A few saplings bound together with strips of rawhide closed it against stray beasts. Bukawai removed the primitive door and pushed Tibo within. The hyenas, snarling, rushed past him and were lost to view in the blackness of the interior. Bukawai replaced the saplings and seizing Tibo roughly by the arm, dragged him along a narrow, rocky passage. The floor was comparatively smooth, for the dirt which lay thick upon it had been trodden and tramped by many feet until few inequalities remained. The passage was tortuous, and as it was very dark and the walls rough and rocky, Tibo was scratched and bruised from the many bumps he received. Bukawai walked as rapidly through the winding gallery as one would traverse a familiar lane by daylight. He knew every twist and turn as a mother knows the face of her child, and he seemed to be in a hurry. He jerked poor little Tibo possibly a trifle more ruthlessly than necessary even at the pace Bukawai set; but the old witch-doctor, an outcast from the society of man, diseased, shunned, hated, feared, was far from possessing an angelic temper. Nature had given him few of the kindlier characteristics of man, and these few Fate had eradicated entirely. Shrewd, cunning, cruel, vindictive, was Bukawai, the witch-doctor. <sep>Who knew every twist and turn of the gallery?<sep>Bukawai

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

Q: (CNN) -- A federal court jury in Florida convicted seven people of participating in a global child pornography trafficking enterprise, according to the Department of Justice. Jurors convicted the seven Wednesday of multiple counts of child exploitation, pornography and obstruction of justice. Members of the organization used Internet news groups to swap and share "illegal images and videos depicting prepubescent children, including toddlers, engaged in various sexual and sadistic acts," prosecutors said. An indictment filed in the case detailed interactions between group members as they swapped and commented on images. "My thanks to you and all the others that together make this the greatest group of pedos to ever gather in one place," Freeman wrote in response to one posting, according to the indictment. And a posting from Castleman, cited in the indictment, read, "Thanks to all for the wonderful material that has been posted." An Australian constable who infiltrated the group in August 2006 was among 50 witnesses testifying at trial. He told the jury that the group traded more than 400,000 images and videos of child sexual abuse before being dismantled by law enforcement, according to the Justice Department statement. Each defendant faces a sentence of 20 years to life in prison, fines and the possibility of supervised release for the rest of their lives, authorities said. The seven will be sentenced April 14. During the six-day trial, evidence showed the seven participated in what prosecutors called a "well-organized criminal enterprise whose purpose was to proliferate child sex abuse images to its membership during a two-year period." "This was a wide-scale, high-volume, international trafficking enterprise that used sophisticated computer encryption technology and file-sharing techniques," Matthew Friedrich, acting assistant attorney general, said in the statement. The seven defendants were James Freeman of Santa Rosa Beach, Florida; Gary Lakey of Anderson, Indiana; Marvin Lambert of Indianapolis, Indiana; Neville McGarity of Medina, Texas; Warren Mumpower of Spokane, Washington; Daniel Castleman of Lubbock, Texas; and Ronald White of Burlington, North Carolina, according to the Department of Justice. <sep>Who told the jury that the group traded more than 400,000 images and videos of child sexual abuse?<sep>Mathew Friedrich
