Please answer this: Given the below context:  For several months after the permanent camp was built, the colonists took short trips to  explore their surroundings. At the end of October 1685, La Salle decided to undertake a longer expedition and reloaded the Belle with many of the remaining supplies. He took 50 men, plus the Belle's crew of 27 sailors, leaving behind 34 men, women, and children. Most of the men traveled with La Salle in canoes, while the Belle followed further off the coast. After three days of travel, they learned of hostile Native Americans in the area. Twenty of the Frenchmen attacked the Native American village, where they found Spanish artifacts. Several of the men died on this expedition from eating prickly pear. The Karankawa killed a small group of the men who had camped on shore, including the captain of the Belle.From January until March 1686, La Salle and most of his men searched overland for the Mississippi River, traveling towards the Rio Grande, possibly as far west as modern-day Langtry, Texas. The men questioned the local Native American tribes, asking for information on the locations of the Spaniards and the Spanish mines, offering gifts, and telling stories that portrayed the Spanish as cruel and the French as benevolent. When the group returned, they were unable to find the Belle where they had left her and were forced to walk back to the fort.The following month they traveled east, hoping to locate the Mississippi and return to Canada. During their travels, the group encountered the Caddo, who gave the Frenchmen a map depicting their territory, that of their neighbors, and the location of the Mississippi River. The Caddo often made friendship pacts with neighboring peoples and extended their policy of peaceful negotiation to the French. While visiting the Caddo, the French met Jumano traders, who reported on the activities of the Spanish in New Mexico. These traders later informed Spanish officials of the Frenchmen they had seen.

Please answer this: Given the below context:  Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present.  Guess a valid title for it!

Please answer this: Given the below context:  Drilling fluids are necessary for borehole stability in deep cores, and can also be used to circulate cuttings away from the bit.  Fluids used include water, ethanol/water and water/ethylene glycol mixtures, petroleum fuels, non-aromatic hydrocarbons, and n-butyl acetate. Water is the cheapest and cleanest option; it may be present on the glacial surface or may be created by thermal drilling.  In cold ice some form of antifreeze is necessary, or heat must be reapplied by reaming the hole periodically. Ethanol and water.  Ethanol acts as an anti-freeze in water; at sufficient concentrations it can reduce the freezing temperature of the mixture to well below any temperature likely to be encountered in ice drilling.  The concentration must be chosen to prevent the liquid freezing and also to maintain the borehole against the ice overburden pressure.  Because the density of the mixture decreases with lower temperatures, vertical convection will develop in boreholes where temperatures decrease with depth, as the lighter mixture rises.  This causes slush to form in the borehole, though successful drilling is still possible.  Ethanol is one of the cheapest options for a drilling fluid, and requires less storage space than other options because in use it is diluted with water.  A Soviet expedition left an 800 m borehole in Antarctica filled with ethanol and water at an ice temperature of −53 °C; after 11 months the borehole remained open and drilling was resumed with no problems.  A problem with this option is that the mixture will penetrate cores that have cracks. Ethylene glycol and water was used at Camp Century in 1966 in the lower part of the hole to dissolve the cuttings. Petroleum fuels.  This includes diesel, jet fuel, and kerosene. They are inexpensive and easily available, and were once in common use; disadvantages include flammability and the aromatics they contain, which are a health hazard. Non-aromatic hydrocarbons.  As of 2009 these had become the most commonly used drilling fluids; eliminating the...  Guess a valid title for it!
