[Q]: She led the way into the cheerful schoolroom, where big girls and little girls were sitting about, amusing themselves in the quiet of a long Sunday afternoon.  Several of the younger children ran to her as she came in, and stood holding fast to the folds of her black habit, staring up at the strangers, while she explained the kind of instruction given, the system, and the order reigning in each department.  Finally, she persuaded a little girl, only six years old, to take her dusky face out of the long flowing veil of the nun, and show how quickly she could read a sentence that Sister Winifred wrote on the blackboard.  Then others were called on, and gave examples of their accomplishments in easy arithmetic and spelling.  The children must have been very much bored with themselves that stormy Sunday, for they entered into the examination with a quite unnatural zest.  Two of the elder girls recited, and some specimens of penmanship and composition were shown.  The delicate complexion of the little nun flushed to a pretty wild-rose pink as these pupils of hers won the Colonel's old fashioned compliments. <sep>What day did the nun enter the schoolroom with the strangers?<sep>Sunday
[A]: Yes


[Q]: The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis. <sep>How does Earth create its magnetism?<sep>Earth has an inner and outer core. consists of liquid metals, mainly iron and nickel.Earths magnetic field is generated here
[A]: Yes


[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>How do warblers and other migrating birds navigate<sep>Use Sun's magnetic force
[A]:
No
