Answer the question at the end by quoting:

Ibn Rushd (Arabic: bn rshd; full name Arabic: 'bw lwlyd mHmd bn Hmd bn rshd, translit. 'Abu l-Walid Muhammad Ibn 'Ahmad Ibn Rushd; 14 April 1126 - 10 December 1198), often Latinized as Averroes (), was a medieval Andalusian Moorish Arab polymath. He wrote on logic, Aristotelian and Islamic philosophy, Islamic theology, the Maliki school of Islamic jurisprudence, psychology, political theory, the theory of Andalusian classical music, geography, mathematics, as well as the medieval sciences of medicine, astronomy, physics, and celestial mechanics. Ibn Rushd was born in Cordoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco.
Ibn Rushd looked to Aristotle as to whether the world was eternal. In his Physics, the Greek philosopher argues that everything that comes into existence does so from a substratum. Therefore, if the underlying matter of the universe came into existence, it would come into existence from a substratum. But the nature of matter is precisely to be the substratum from which other things arise. Consequently, the underlying matter of the universe could have come into evidence only from an already existing matter exactly like itself; to assume that the underlying matter of the universe came into existence would require assuming that an underlying matter already existed. As this assumption is self-contradictory, Aristotle argued, matter must be eternal. Because in his eyes, "Aristotle demonstrated the eternity of matter", Ibn Rushd "abandon[ed] belief in the creation out of nothing." This is not to say that Ibn Rushd denied the Creation; rather, he proposed an eternal creation. Oliver Leaman explains Ibn Rushd's argument as such: We [as humans] can decide to do something, we can wait for a certain time before acting, we can wonder about our future actions; but such possibilities cannot arise for [an eternal, omnipotent, omnipresent] God. In his case there is no gap between desire and action, nothing stands in the way of his activity; and yet we are told by al-Ghazali that God suddenly created the world. What differentiates one time from another for God? What could motivate him to create the world at one particular time as opposed to another? For us, different times are different because they have different qualitative aspects, yet before the creation of the world, when there was nothing around to characterize one time as distinct from another, there is nothing to characterize one time over another as the time for creation to take place.

What was the eternity of the world?

Ibn Rushd looked to Aristotle as to whether the world was eternal. In his Physics, the Greek philosopher argues that everything that comes into existence does so from a substratum.

Some context: Harriet Tubman (born Araminta Ross, c. 1822 - March 10, 1913) was an American abolitionist. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry.
By 1840, Tubman's father, Ben, was manumitted from slavery at the age of 45, as stipulated in a former owner's will, though his actual age was closer to 55. He continued working as a timber estimator and foreman for the Thompson family, who had held him as a slave. Several years later, Tubman contacted a white attorney and paid him five dollars to investigate her mother's legal status. The lawyer discovered that a former owner had issued instructions that Rit, like her husband, would be manumitted at the age of 45. The record showed that a similar provision would apply to Rit's children, and that any children born after she reached 45 years of age were legally free, but the Pattison and Brodess families had ignored this stipulation when they inherited the slaves. Challenging it legally was an impossible task for Tubman. Around 1844, she married a free black man named John Tubman. Although little is known about him or their time together, the union was complicated because of her slave status. Since the mother's status dictated that of children, any children born to Harriet and John would be enslaved. Such blended marriages - free people of color marrying enslaved people - were not uncommon on the Eastern Shore of Maryland, where by this time, half the black population was free. Most African-American families had both free and enslaved members. Larson suggests that they might have planned to buy Tubman's freedom. Tubman changed her name from Araminta to Harriet soon after her marriage, though the exact timing is unclear. Larson suggests this happened right after the wedding, and Clinton suggests that it coincided with Tubman's plans to escape from slavery. She adopted her mother's name, possibly as part of a religious conversion, or to honor another relative.
How many times did Harriet Tubman get married?
A: she married a free black man named John Tubman.

IN: Kara (Hangul: kara, Japanese: kara, often stylized as KARA) was a South Korean pop girl group formed by DSP Media in 2007. The group's final lineup was composed of Park Gyuri, Han Seungyeon, Goo Hara and Heo Youngji. Members Nicole Jung and Kang Ji-young officially departed from the group in 2014, while Kim Sung-hee left in 2008. The group's name comes from the Greek word "chara" (khara, lit. "joy"), which they interpreted to mean "sweet melody".

The group was scheduled to have their comeback in March 2008 with their second album, however, member Kim Sung-hee suddenly announced that she would be leaving the group due to parental pressure because her participation in the group was contingent on the maintenance of her grades. In response, DSP stated that the second album that was recorded would be shelved and replaced by a mini-album to come in May; in addition, two members would join the group. Auditions were held, and the two new members were eventually revealed to be Goo Ha-ra and Kang Jiyoung. The group made their return in the music industry as a quintet on July 24, 2008 with "Rock U" on M! Countdown. They made their comeback with the "cute" and "playful" image which was the complete opposite of the group's original image from their debut. In the same month, their first mini-album titled Rock U was also released. The second season of Kara Self Camera was premiered on August 18, 2008, which chronicled how the group was adapting to their two new members. On November 29, 2008, DSP released a teaser video for their upcoming single, "Pretty Girl", which received over 40,000 hits within 12 hours. The full video was released on December 2, 2008 online and was positively received by the public. The EP, Pretty Girl, was released on December 4, embodying a "fun-party" concept. The group began its comeback on all major music shows on December 4, 2008, starting with M! Countdown. During their first national performance on KBS's Music Bank, member Goo Hara accidentally gasped "ah!" live on air due to slipping on falling confetti, and reportedly cried profusely afterwards. The incident became a hot issue to many viewers, but Goo Hara received comfort instead of criticism from the general public. Park Gyuri attributed their popularity increase to their "pretty but natural" appeal, while media reports gave credit to the band for finally finding its own identity in the music industry since the group's debut and to older male fans, most notably singer Shin Hae Chul. Due to their increasingly hectic schedule as their popularity rose, a few of the group's members were taken to the hospital on December 19 after a Music Bank rehearsal for cold symptoms and exhaustion.
