Input: The Glory of Melaka: In the early days, if you were not a pirate or a mosquito, Melaka was not much of a place to live. The land was infertile, just a swampy plain, the river small and sluggish. But it had a sheltered harbor, protected from the monsoons by neighboring Sumatra. Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean. The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese. In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka. They made Parameswara an offer he could not refuse: port facilities and an annual financial tribute in exchange for Chinese protection against the marauding Thais. In 1411, Parameswara took the money to Beijing himself, and the emperor gratefully made him a vassal king. Twenty years later, the Chinese withdrew again from the South Seas trade. The new ruler of Melaka, Sri Maharajah, switched his allegiance to the Muslim trading fraternity by marrying into the Muslim faith, wedding the daughter of a sultan in Sumatra. Islam won its place in Malaya not by conquestas had been the case in North Africa and Europebut by trade, dynastic alliances, and peaceful preaching. Bengali peddlers had already brought the faith to the east coast. In Melaka and throughout the peninsula, Islam thrived as a strong, male-dominated religion of individuality, offering dynamic leadership and preaching brotherhood and self-relianceall qualities ideally suited to the coastal trade. At the same time, Sufi mystics synthesized Islamic teaching with local Malay traditions of animistic magic and charisma, though Islam did not become the state religion until Muzaffar Shah became sultan of Melaka (14461459). But the key figure in the sultanate was Tun Perak, bendahara (prime minister) and military commander. He expanded Melaka's power along the west coast and down to Singapore and the neighboring Bintan islands. He also had orang laut pirates patrolling the seas to extort tribute from passing ships. After Ailied district chiefs had repelled assaults from Thai-controlled armies from Pahang, Tun Perak personally led a famous victory over a Thai fleet off Batu Pahat in 1456.

Does the response "Infertile land" correctly answer the question "Why was Melaka not an ideal place for most people to live in its early days?"?

(CNN) -- A Christian evangelical group said Thursday that a Bible school -- backed by American evangelist Franklin Graham -- was destroyed in the latest bombing raid to hit South Kordofan, an oil-rich Sudanese province that borders the newly created independent country of South Sudan. At least eight bombs were dropped in the area Wednesday during the school's first day of classes, according to a statement by Samaritan's Purse, Graham's Christian humanitarian group, which supports the school. Two bombs landed inside the compound -- located in the region's Nuba Mountains -- destroying two Heiban Bible College buildings and igniting grass fires across the area, the group said in a statement No injuries were reported. "It was a miracle that no one was injured," the statement added. Graham, who has called on the international community to take out Sudan's air assets and establish a no-fly zone in the region, said in a statement Thursday that he blamed Sudan's air force for the strike. At least four churches have been destroyed since August, the group said. "We are deeply concerned for the welfare and lives of the people of South Kordofan and we condemn the bombing of churches and Christian facilities," added Graham, son of the famed Rev. Billy Graham. More than 78,000 people have fled South Kordofan and Blue Nile states since August of last year after an armed rebellion took root, the United Nations reported. The Sudanese government is thought to have responded to the rebellion by conducting sustained air raids with the use of Russian-made Antonov bombers, which have raised concerns over civilian casualties. Decades of civil war between the north and south, costing as many as 2 million lives, formally ended with a U.S.-brokered peace treaty in 2005.

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.

Question: "What is the purpose of a compass and what does it detect?"

Response: "To detect Earths magnetic north pole and detect direction"

Problem: Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better.

Question: "What do we use electromagnetic energy for?"

Answer: "To make our lives better"

We were cornered in a sort of way already. But these butchers up the cavern had been surprised, they were probably scared, and they had no special weapons, only those little hatchets of theirs. And that way lay escape. Their sturdy little forms--ever so much shorter and thicker than the mooncalf herds--were scattered up the slope in a way that was eloquent of indecision. I had the moral advantage of a mad bull in a street. But for all that, there seemed a tremendous crowd of them. Very probably there was. Those Selenites down the cleft had certainly some infernally long spears. It might be they had other surprises for us.... But, confound it! if we charged up the cave we should let them up behind us, and if we didn't those little brutes up the cave would probably get reinforced. Heaven alone knew what tremendous engines of warfare--guns, bombs, terrestrial torpedoes--this unknown world below our feet, this vaster world of which we had only pricked the outer cuticle, might not presently send up to our destruction. It became clear the only thing to do was to charge! It became clearer as the legs of a number of fresh Selenites appeared running down the cavern towards us.

Question: "Where are the Selenites in relation to the narrator?"

Response: "Below the cavern"
