Background: Eratosthenes of Cyrene (; Greek: Eratosthenes o Kurenaios, IPA:
Context: Eratosthenes now continued from his knowledge about the Earth. Using his discoveries and knowledge of its size and shape, he began to sketch it. In the Library of Alexandria he had access to various travel books, which contained various items of information and representations of the world that needed to be pieced together in some organized format. In his three-volume work Geography (Greek: [Geographika] ), he described and mapped his entire known world, even dividing the Earth into five climate zones: two freezing zones around the poles, two temperate zones, and a zone encompassing the equator and the tropics. He had invented geography. He created terminology that is still used today. He placed grids of overlapping lines over the surface of the Earth. He used parallels and meridians to link together every place in the world. It was now possible to estimate one's distance from remote locations with this network over the surface of the Earth. In the Geography the names of over 400 cities and their locations were shown: this had never been achieved before. Unfortunately, his Geography has been lost to history, but fragments of the work can be pieced together from other great historians like Pliny, Polybius, Strabo, and Marcianus. The first book was something of an introduction and gave a review of his predecessors, recognizing their contributions that he compiled in the library. In this book Eratosthenes denounced Homer as not providing any insight into what he now described as geography. His disapproval of Homer's topography angered many who believed the world depicted in the Odyssey to be legitimate. He also commented on the ideas of the nature and origin of the Earth: he had thought of Earth as an immovable globe; while on its surface was a place that was changing. He had hypothesized that at one time the Mediterranean was a vast lake that covered the countries that surrounded it; and had only become connected to the ocean to the west when a passage had opened up sometime in its history. In the second book is his discovery about the circumference of the Earth. This is where, according to Pliny, "The world was grasped." Eratosthenes described his famous story of the well in Syene, described above. This book would now be considered a text on mathematical geography. His third book of the Geography contained political geography. He cited countries and used parallel lines to divide the map into sections, to give accurate descriptions of the realms. This was a breakthrough, and can be considered the beginning of geography.
Question: Were his maps accurate?
Answer: even dividing the Earth into five climate zones: two freezing zones around the poles, two temperate zones, and a zone encompassing the equator and the tropics.

Background: Andrea Jane Corr MBE (born 17 May 1974) is an Irish musician, songwriter, and actress. Corr debuted in 1990 as the lead singer of the Celtic folk rock and pop rock group The Corrs along with her three elder siblings Caroline, Sharon, and Jim. Aside from singing lead vocals Corr plays the tin whistle, the ukulele, and the piano.
Context: While her siblings were on hiatus to raise their families, Andrea launched a solo career. She released her first album, Ten Feet High, on 25 June 2007. It was produced by Nellee Hooper, who has worked with Gwen Stefani and Madonna; Bono was an executive producer. Her first single, "Shame on You" was an up-tempo pop song about men and women going to war and leaving behind partners they may never see again. It received positive reviews from music critics; IndieLondon described the song as a "slick package" that was "polished, well produced and with a message that's difficult to ignore". Losing Today's David Adair gave the song a strong review, writing that Corr's vocals were "crisp and uplifting". Liverpool's Daily Post gave the song a three-star rating, commenting that it was "deceptively upbeat", which masked its "heavier message about conscription and war". On 10 April 2009 Andrea announced on Claudia Winkleman's BBC Radio 2 show that she would be releasing a second album of old songs and covers. She spoke of her disappointment and how 'gutted' she had been when her 2007 album Ten Feet High had failed to gain commercial success. She also spoke at length of her experiences while acting in the play Dancing at Lughnasa and how it has given her hope for upcoming projects, including a second solo album of 'old songs'. In late January 2011, her new album was announced for "early summer", and a downloadable MP3 of her cover of John Lennon's Number 9 Dream was made available to subscribers. Lifelines was released on 30 May. In the summer of 2012, she re-recorded the track "Pale Blue Eyes" (which had first appeared on her album "Lifelines") with German electronic musician Christopher von Deylen, better known under his alias Schiller. It was released in Germany on 5 October on the Schiller album Sonne.
Question: Why did Corr take on a solo career?
Answer: While her siblings were on hiatus to raise their families, Andrea launched a solo career.

Background: The Corrs are an Irish band that combine pop rock with traditional Irish themes within their music. The group consists of the Corr siblings; Andrea (lead vocals, tin whistle, ukulele); Sharon (violin, vocals); Caroline (drums, percussion, piano, bodhran, vocals) and Jim (guitar, piano, keyboards, vocals). They are from Dundalk, County Louth, Ireland. The Corrs have released seven studio albums and numerous singles, which have reached Platinum in many countries, and have sold 40 million albums worldwide.
Context: Jason Flom, Atlantic Records's head of A&R, recommended that they meet David Foster, a Canadian musician, producer, composer and arranger. The Corrs played live for Foster and he agreed to sign them to Atlantic Records. They extended their stay in the US for over five months to record their debut album, Forgiven, Not Forgotten. It featured six instrumental selections among its Celtic-influenced tracks. The album sold well in Ireland, Australia, Japan, Norway and Spain. Major success in the US and the UK, however, was not immediately forthcoming. Eventually, the album reached Platinum status in the UK and Australia, and 4x Platinum in Ireland, making it one of the most successful debuts by an Irish group. The Corrs' next album, 1997's Talk on Corners, was produced by Glen Ballard, who was respected for his collaboration with Alanis Morissette. The Corrs also collaborated with Carole Bayer Sager, Oliver Leiber, Rick Nowels and Billy Steinberg. The album met with lukewarm response. It was successful in Ireland and entered the Australian album charts at number 3. After the band recorded a version of Dreams for a Fleetwood Mac tribute album, they re-released Talk on Corners, with new remixes of "What Can I Do?", "So Young" and "Runaway". The special edition topped the charts worldwide and again reached multi-Platinum status in the UK and Australia. In June 1998, The Corrs participated in the Pavarotti and Friends for the Children of Liberia charity concert. The concert was held in Modena, Italy and was hosted by Luciano Pavarotti. Other performers included Jon Bon Jovi, Celine Dion, Spice Girls and Stevie Wonder. The concert aimed to raise money to build the Pavarotti and Friends Liberian Children's Village, to provide refuge for children in Liberia. The following year, The Corrs received a BRIT Award for Best International Band. They performed live on MTV's Unplugged on 5 October 1999 at Ardmore Studios, Co. Wicklow, Ireland. The resulting CD and DVD sold 2.7 million copies and featured live performances of previously released songs, plus a new song, "Radio", later featured on their third album, In Blue.
Question: Did the album later do better on the charts?
Answer:
Eventually, the album reached Platinum status in the UK and Australia, and 4x Platinum in Ireland, making it one of the most successful debuts by an Irish group.
