PROBLEM: Context: Hubble measured the distances to galaxies. He also studied the motions of galaxies. In doing these things, Hubble noticed a relationship. This is now called Hubbles Law: The farther away a galaxy is, the faster it is moving away from us. There was only one conclusion he could draw from this. The universe is expanding! Figure 26.15 shows a simple diagram of the expanding universe. Imagine a balloon covered with tiny dots. When you blow up the balloon, the rubber stretches. The dots slowly move away from each other as the space between them increases. In an expanding universe, the space between galaxies is expanding. We see this as the other galaxies moving away from us. We also see that galaxies farther away from us move away faster than nearby galaxies. About 13.7 billion years ago, the entire universe was packed together. Everything was squeezed into a tiny volume. Then there was an enormous explosion. After this big bang, the universe expanded rapidly (Figure 26.16). All of the matter and energy in the universe has been expanding ever since. Scientists have evidence this is how the universe formed. One piece of evidence is that we see galaxies moving away from us. If they are moving apart, they must once have been together. Also, there is energy left over from this explosion throughout the universe. The theory for the origin of the universe is called the Big Bang Theory. In the first few moments after the Big Bang, the universe was extremely hot and dense. As the universe expanded, it became less dense. It began to cool. First protons, neutrons, and electrons formed. From these particles came hydrogen. Nuclear fusion created helium atoms. Some parts of the universe had matter that was densely packed. Enormous clumps of matter were held together by gravity. Eventually this material became the gas clouds, stars, galaxies, and other structures that we see in the universe today. We see many objects out in space that emit light. This matter is contained in stars, and the stars are contained in galaxies. Scientists think that stars and galaxies make up only a small part of the matter in the universe. The rest of the matter is called dark matter. Dark matter doesnt emit light, so we cant see it. We know it is there because it affects the motion of objects around it. For example, astronomers measure how spiral galaxies rotate. The outside edges of a galaxy rotate at the same speed as parts closer to the center. This can only be explained if there is a lot more matter in the galaxy than we can see. What is dark matter? Actually, we dont really know. Dark matter could just be ordinary matter, like what makes up Earth. The universe could contain lots of objects that dont have enough mass to glow on their own. There might just be a lot of black holes. Another possibility is that the universe contains a lot of matter that is different from anything we know. If it doesnt interact much with ordinary matter, it would be very difficult or impossible to detect directly. Most scientists who study dark matter think it is a combination. Ordinary matter is part of it. That is mixed with some kind of matter that we havent discovered yet. Most scientists think that ordinary matter is less than half of the total matter in the universe. We know that the universe is expanding. Astronomers have wondered if it is expanding fast enough to escape the pull of gravity. Would the universe just expand forever? If it could not escape the pull of gravity, would it someday start to contract? This means it would eventually get squeezed together in a big crunch. This is the opposite of the Big Bang. Scientists may now have an answer. Recently, astronomers have discovered that the universe is expanding even faster than before. What is causing the expansion to accelerate? One hypothesis is that there is energy out in the universe that we cant see. Astronomers call this dark energy. We know even less about dark energy than we know about dark matter. Some scientists think that dark energy makes up

PROBLEM: Context: The Caste War of Yucatan was a conflict that lasted from 1847 to 1901. It began with the revolt of native Maya people led by Maya chiefs Jacinto Pat and Cecilio Chi, against the population of European descent called "Yucatecos", who had political and economic control. A lengthy war ensued between the Yucateco forces in the north-west of the Yucatan and the independent Maya in the south-east. It officially ended with the occupation of the Maya capital of Chan Santa Cruz by the Mexican army in 1901, although skirmishes with villages and small settlements that refused to acknowledge Mexican control continued for over another decade. Adam Jones wrote: "This ferocious race war featured genocidal atrocities on both sides, with up to 200,000 killed." Because of the conflict, on November 24, 1902, Yucatan had a second territorial division when Porfirio Diaz decreed the creation of the Federal Territory of Quintana Roo, with capital in the port of Payo Obispo . In little more than half a century, Yucatan lost more than two thirds of its original territory. 
 Question: Who had control of the area after 1901?

SOLUTION: mexican army

PROBLEM: Context: The film opens with narration over a silhouette of Hill House at night. The narrator, Dr. John Markway (Richard Johnson) tells us, "An evil old house, the kind some people call haunted is like an undiscovered country waiting to be explored. Hill House had stood for 90 years and might stand for 90 more. Silence lay steadily against the wood and stone of Hill House. Whatever walked there walked alone." Title and credits follow, then narration continues, "Scandal, murder, insanity, suicide: The history of Hill House was ideal. It had everything I wanted..." The house was built in New England by a man named Hugh Crain for his wife and young daughter. A horse and carriage accident took the life of the first Mrs. Crain (an uncredited Pamela Buckley) before she even saw the house. Hugh Crain (an uncredited Howard Lang) and young daughter, Abigail (an uncredited Janet Mansell) said a few words over the body, but Hugh was left an embittered man. Crain married again, and the second Mrs. Crain (an uncredited Freda Knorr) also died, falling down the main staircase. Hugh Crain left Abigail with a nurse (an uncredited Susan Richards) and went to England where he died in a drowning accident. Abigail kept the same nursery room her entire life. By the time she was eighty (an uncredited Amy Dalby) she was a bedridden invalid. Her nurse-companion (an uncredited Rosemary Dorken) was a local girl and, it is with this young companion the evil reputation of Hill House really begins. The old lady died while calling for help. The companion was trysting on the verandah with a farm hand. The companion inherited Hill House and occupied it for many years, but eventually hanged herself. The house then passed to a distant relative, named Mrs. Sanderson (Fay Compton).Markway visits Mrs. Sanderson where he convinces her to let him use the house for psychic research. He explains, "I shall occupy the house with a group of carefully selected assistants...I must have specially qualified help to take notes and document any evidence of the supernatural I may find." Eldridge Harper (Ronald Adam), Mrs. Sanderson's lawyer, voices his concern about publicity seekers and the propriety of having women in the house. Harper suggests to Mrs. Sanderson that her nephew, Luke, joins the doctor at Hill House, as he expects to inherit the property. Mrs. Sanderson asks point blank, "Exactly what do you and your assistants expect to find at Hill House?" Markway replies, "Maybe only a few loose floorboards, and maybe, I only say maybe, the key to another world."Dr. Markway, taking a leave of absence from his university professorship, finalizes his list of assistants. Only two end up accepting, Eleanor Lance and Theodora (no last name).Eleanor Lance (Julie Harris) is living with her sister. She is nearly broke and weary after looking after her invalid mother non-stop for eleven years. Mother is now dead, and she fights with her sister over just about everything. She begs to use the car, which is after all, half hers. Her brother-in-law, Bud Fredericks (an uncredited Paul Maxwell) tries to act as mediator between Eleanor and his wife, Carrie (Diane Clare). He is sympathetic to Eleanor's plight, but their daughter, Dora (an uncredited Verina Greenlaw) takes her cues from her mother, and taunts her Aunt Eleanor. On the vacation plan, Bud sides with Eleanor, "I think you should have a vacation, Nell." Carrie objects, but Eleanor is not to be deterred and she shows her family how she reacts when pushed to her breaking point. She is normally quiet and meek, but when pushed is loud and assertive.Nell decides to take the car and confronts the garage attendant (an uncredited Claude Jones) for the keys. She departs Boston along U.S. 50 and Route 238 to Hill House. We hear Nell thinking and she reveals she will never return to live with her sister. In fact, most of what we learn of Eleanor is hearing her thoughts.Eleanor
