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. 

Question: "What do we know and don't about the Earth and magnets?"

Answer: "By studying earthquake waves they were able to learn about Earths interior"

Response: no


As where to guard the walls, full many a foss Begirds some stately castle, sure defence Affording to the space within, so here Were model'd these; and as like fortresses E'en from their threshold to the brink without, Are flank'd with bridges; from the rock's low base Thus flinty paths advanc'd, that 'cross the moles And dikes, struck onward far as to the gulf, That in one bound collected cuts them off.  Such was the place, wherein we found ourselves From Geryon's back dislodg'd.  The bard to left Held on his way, and I behind him mov'd.  On our right hand new misery I saw, New pains, new executioners of wrath, That swarming peopled the first chasm.  Below Were naked sinners.  Hitherward they came, Meeting our faces from the middle point, With us beyond but with a larger stride.  E'en thus the Romans, when the year returns Of Jubilee, with better speed to rid The thronging multitudes, their means devise For such as pass the bridge; that on one side All front toward the castle, and approach Saint Peter's fane, on th' other towards the mount. 

Question: "Which way did the naked sinners come?"

Answer: "Sinners came from above"

Response: no


What a time of it Dawson's Landing was having!  All its life it had been asleep, but now it hardly got a chance for a nod, so swiftly did big events and crashing surprises come along in one another's wake: Friday morning, first glimpse of Real Nobility, also grand reception at Aunt Patsy Cooper's, also great robber raid; Friday evening, dramatic kicking of the heir of the chief citizen in presence of four hundred people; Saturday morning, emergence as practicing lawyer of the long-submerged Pudd'nhead Wilson; Saturday night, duel between chief citizen and titled stranger.  The people took more pride in the duel than in all the other events put together, perhaps.  It was a glory to their town to have such a thing happen there.  In their eyes the principals had reached the summit of human honor.  Everybody paid homage to their names; their praises were in all mouths.  Even the duelists' subordinates came in for a handsome share of the public approbation: wherefore Pudd'nhead Wilson was suddenly become a man of consequence.  When asked to run for the mayoralty Saturday night, he was risking defeat, but Sunday morning found him a made man and his success assured. 

Question: "Why did Dawson's Landing wake up?"

Answer: "Real Nobility, grand reception, robber raid, kicking, duel"

Response: yes


As food is pushed along, it undergoes digestion. Digestion is the process of breaking down food into nutrients. There are two types of digestion: mechanical digestion and chemical digestion. Mechanical digestion occurs when large chunks are turned into smaller chucks. Perhaps not surprisingly, this happens when you chew your food. Once you swallow the food, your stomach also does some of this work. Chemical digestion occurs when food is broken down into useful nutrients. This is a chemical process that begins as you start to chew your food. The saliva in your mouth starts this process. Once you swallow, the acid in your stomach further breaks down food. From the stomach, the foods moves into the small intestine. In the small intestines, another set of chemicals goes to work. Are you surprised? Your small intestine, and not your stomach, does most of the work! 

Question: "What type of digestion happens when you chew your food?"

Answer: "Mechanical Digestion"

Response:
yes
