Question: Which war occured first, the Seven Years' war or the Napoleonic Wars? Passage 1:FranceUnited Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK). The historical ties between France and the UK, and the countries preceding them, are long and complex, including conquest, wars, and alliances at various points in history. The Roman era saw both areas, except northern England and Scotland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained. The Norman conquest of England in 1066 decisively shaped English history, as well as the English language. In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France. Some of the noteworthy conflicts include the Hundred Years' War and the French Revolutionary Wars which were French victories, and the Seven Years' War, Second Hundred Years' War and Napoleonic Wars, from which Britain emerged victorious.

In 1997, the team now consisting of Don Walchuk at third and Rudy Ramcharan at second placed fourth. At the 2002 Winter Olympics now with Carter Rycroft at second, the team won a silver medal. With Martin, Bartlett has been to seven Briers and has won two Canada Cups. Before Martin, Barlett played with Pat Ryan. He went to the 1985 Brier as his alternate player.
Passage 2:During the Middle Ages of Indian history, many faiths and sects sprang up in religious and social spheres of Hindu society. Their practitioners slowly migrated away from the teachings of the Vedas attaching greater significance to their founders and their preachings. From then onwards polytheism commenced. Great differences developed among the different sects and divided and weakened Hindu society. The caste system based on birth became strong and gave rise to further fragmentation. Like with any aging society without reforms, the customs gave way to superstition and ignorance wherein practice superseded reason and the spread of blind faith threatened degradation of "Hindu" society. The word Hindu is an improper word or misnomer- the correct word is Vedantic or Sanathana Dharma, a religion based upon the Vedas. The word Hindu does not appear any where in the Vedic texts or even the Bhagavad Gita. The word Hindu is a Persian word, used by the Muslims and the renaming of the Vedantic religion to "Hindu" demonstrates the level of weakening to the Vedantic faith. "Hinduism" needs reforms.
Passage 3:After her education from private teachers in Istanbul, she traveled to Paris, France in 1898 to meet her elder brother Ahmet Rza, who was a member of the Young Turks movement. She studied in Sorbonne University, and was affiliated to the Committee of Union and Progress (CUP). She was the only female member of the committee. In Paris, she wrote in two newspapers published by CUP in Paris namely Mechveret Supplement Francais in French and Sura'i Himmet in Turkish. In 1908, she returned to Istanbul, where she wrote in two newspapers; Hanmlara Mahsus Gazete ("Newspaper for Women") and Kadnlar Dunyas ("Ladies' World"). She also became the secretary general of Turkish Red Crescent between 19081913. During the last years of the Ottoman Empire, she worked hard to transform the Adile Sultan Palace, a royal palace in Istanbul, to a girls' school. With the help of her brother, she succeeded and the palace was used as Kandilli High School for Girls up to 1986, when it was partially burned down.

Question: What is the scientific name of the flowers solitary bees often visit? Passage 1:LCD Soundsystem released "Call the Police" and "American Dream" together as a digital double-A-side single on May 5, 2017, acting as the lead single from the album. The two songs were made available for listening once midnight was reached in one's time zone. The band promoted the songs by performing both during the May 6 episode of the 42nd season of Saturday Night Live. On August 4, the band rolled out an ice cream truck outside of the Lollapalooza festival in Chicago promoting the album. The truck played songs from the album in the form of ice cream jingles through its speaker. A Twitter account for the truck was also launched to provide updates on where its current location was. On August 16, "Tonite" was premiered on Zane Lowe's radio show on Beats 1. Along with the premiere was the release of a music video for the track, directed by Joel Kefali. It was also subsequently made available for streaming on Spotify. A virtual reality experience made to accompany the song, titled "Dance Tonite", was released to the public on August 22, though first previewed privately in June. Available to use in an Internet browser, the experience allowed people with room scale virtual reality kits, such as the Oculus Rift, to dance along to the track. Those with more simpler VR headsets, like the Daydream View, could view the experience as well the dance performances done by others. The band teamed up with the Puckney and Moniker design studios from Amsterdam for the project, alongside Google's data arts team. On August 31, the band released a 14-minute instrumental track called "Pulse (v.1)" as a free download. On Facebook, Murphy wrote that the track was "not precisely part of the record," but instead thought of it as an "addendum" meant to be played after the album's closing track, "Black Screen". It was originally left off of American Dream due to it not being able to fit on the vinyl format of the album. A music video for "Oh Baby", directed by Rian Johnson, was released on September 20, 2018. The video depicts an elderly couple, portrayed by Sissy Spacek and David Strathairn, who build a teleporter in their garage.
Passage 2:Asante began his senior career in England with Birmingham City. He made his first-team debut in the Europa League play-off round second leg against C.D. Nacional in August 2011, and made his debut in the Football League while on loan at Northampton Town in January 2012. He had spells on loan at Shrewsbury Town in both 201213 and 201314, but injury disrupted his progress, and he left Birmingham when his contract expired. Without a club while recovering from injury, he spent the latter part of the 201415 season with Kidderminster Harriers before moving on to Solihull Moors, with whom he won the National League North title. Asante signed for Grimsby Town in January 2017, after missing the first couple of months of 201718 recovering from injury, he went on loan to Solihull Moors, however, he left Grimsby by mutual consent in February 2018. He completed the season with Tamworth, and after a short spell on loan at Chester, he joined them permanently in January 2019.
Passage 3:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.
