Input: Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice.
"Water and wind erosion called the geographical features in Illinois. True or False?" is "True"?

Input: Expansion quickly peaked however, and the European powers who had carved up the New World set about testing each other in dynastic conflicts and colonial rivalry. The English were the main rivals of the Dutch on the high seas, and there were several wars between the two in the 17th and 18th centuries. In 16651667 the Dutch sailed up the River Medway and sank the British fleet moored there. The 18th century saw Amsterdam grow into the foremost financial center in the world, but the seeds of decline had already been planted. When the English colonies in New England rose up in revolt against the British, they found ready Ailies in the Dutch. From their colonies in the Caribbean they sent caches of arms and ammunition. The British were furious and went to war in 1780, destroying the Dutch navy and signaling a sudden decline in power and influence from which the Netherlands never recovered. Trade suffered to such an extent that in 1791 the VOC went into liquidation. In the latter part of the century there were anti-Orange demonstrations by pro-French factions in the country, and in 1795 Napoleon Bonaparte took the Netherlands in his epic march across Europe. Under the yoke of another foreign power, and with trade at an all time low, the Golden Age was truly dead. The Return of the House of Orange Napoleon installed his brother Louis as King of Holland and he chose to take the fine Town Hall on Dam Square as his palacenow the Koninklijk Palace. But only four years later he fled the city after civil disturbances broke out when he raised taxes. When Napoleon's bubble burst and French power began to wane, William of Orange emerged from exile and was proclaimed king in 1813. Amsterdam had to work its way out of economic decline, but throughout the 19th century the city grew steadily. Industrialization changed the city. With the building of the Central Station at the end of the century, Amsterdam turned its back on its seafaring past and looked towards the mechanical age for its future. The station was built over the old harbor wall and some of the oldest canals in the city center were filled in to allow better access to motorized vehicles. Dam Square was landlocked for the first time in its history.

Does the response "Industrialization" correctly answer the question "The building of the Central Station occurred at the end of which century?"?

The Dutch Take Over: Intent on capturing a piece of the Portuguese trade in pepper and other spices, the Java-based Dutch Ailied with the Malays in 1633 to blockade Melaka. The trade blockade was to last eight years, and ended in a seven-month siege. The Portuguese surrendered in 1641, wracked by malaria and dysentery and denied their usual reinforcements from Goa. By then, the city had become a stagnant backwater. Unlike the Portuguese, the Dutch decided to do business with the Malays of Johor, who controlled the southern half of the peninsula together with Singapore and the neighboring Riau islands. A trade treaty gave the Dutch command of the spice trade but reserved Johor's rights in tin exports from Perak, Selangor, and Klang. Without ever retrieving the supremacy of the old Melaka sultanate, Johor had become the strongest Asian power in the region. For the Dutch, Johor provided a buffer against other Europeans. Meanwhile, fresh blood came in with the migration into the southern interior of hardy Minangkabau farmers from Sumatra, while tough Bugis warriors from the east Indonesian Celebes (Sulawesi) roved the length and breadth of the peninsula. The Minangkabau custom of freely electing their leaders provided the model for rulership elections in modern federal Malaysia. Their confederation of States became today's Negeri Sembilan ("Nine States"), with Seremban as its capital. The name Minangkabau itself means roughly "buffalo horns" and is reflected in the distinctive upward curving roof in museums and government offices built in the traditional Minangkabau style. The Bugis were energetic merchants and great sailors. With the Dutch concentrating once more on Java and the Moluccas in the 18th century, the Bugis took advantage of the vacuum by raiding Perak and Kedah, imposing their chieftains in Selangor and becoming the power behind the throne in Johor. The Bugis in Johor's administration provided much of the spirit in that State's independent stand in the 19th and 20th centuries. Throughout this period, the east coast states enjoyed a relatively tranquil prosperity, Terengganu notably thriving from its textile industry and trading in pepper and gold with the Thais, Cambodians, and Chinese. The British, under the private auspices of the East India Company (EIC), were beginning to poke their noses into North Borneo.

Question: "During what centuries did Terengganu thrive from its textile industry and trading in pepper and gold?"

OPTIONS:
- no
- yes

Problem: Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

Question: "Electric current is a flow of electrons. Do electrons have a negative or positive charge?"

Answer: "Negative Only"

OPTIONS:
- no
- yes
Answer:
yes
