Some important texts were created and studied by scholars. Philosophical works written by Yang Xiong (53 BC – 18 AD), Huan Tan (43 BC – 28 AD), Wang Chong (27–100 AD), and Wang Fu (78–163 AD) questioned whether human nature was innately good or evil and posed challenges to Dong's universal order. The Records of the Grand Historian by Sima Tan (d. 110 BC) and his son Sima Qian (145–86 BC) established the standard model for all of imperial China's Standard Histories, such as the Book of Han written by Ban Biao (3–54 AD), his son Ban Gu (32–92 AD), and his daughter Ban Zhao (45–116 AD). There were dictionaries such as the Shuowen Jiezi by Xu Shen (c. 58 – c. 147 AD) and the Fangyan by Yang Xiong. Biographies on important figures were written by various gentrymen. Han dynasty poetry was dominated by the fu genre, which achieved its greatest prominence during the reign of Emperor Wu.
Who had produced biographies of individuals of significant importance?
A: various gentrymen

Many early immigrant groups traveled to America to worship freely, particularly after the English Civil War and religious conflict in France and Germany. They included nonconformists like the Puritans, who were Protestant Christians fleeing religious persecution from the Anglican King of England. Despite a common background, the groups' views on religious toleration were mixed. While some such as Roger Williams of Rhode Island and William Penn of Pennsylvania ensured the protection of religious minorities within their colonies, others like the Plymouth Colony and Massachusetts Bay Colony had established churches. The Dutch colony of New Netherland established the Dutch Reformed Church and outlawed all other worship, though enforcement was sparse. Religious conformity was desired partly for financial reasons: the established Church was responsible for poverty relief, putting dissenting churches at a significant disadvantage.
 Who wasn't persecuting the Puritans?
A: unanswerable

At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.
When was a new sytle of carved top and back construction mandolins created?
A: end of the 19th century

Sleep does not affect acquisition or recall while one is awake. Therefore, sleep has the greatest effect on memory consolidation. During sleep, the neural connections in the brain are strengthened. This enhances the brain’s abilities to stabilize and retain memories. There have been several studies which show that sleep improves the retention of memory, as memories are enhanced through active consolidation. System consolidation takes place during slow-wave sleep (SWS). This process implicates that memories are reactivated during sleep, but that the process doesn’t enhance every memory. It also implicates that qualitative changes are made to the memories when they are transferred to long-term store during sleep. When you are sleeping, the hippocampus replays the events of the day for the neocortex. The neocortex then reviews and processes memories, which moves them into long-term memory. When you do not get enough sleep it makes it more difficult to learn as these neural connections are not as strong, resulting in a lower retention rate of memories. Sleep deprivation makes it harder to focus, resulting in inefficient learning. Furthermore, some studies have shown that sleep deprivation can lead to false memories as the memories are not properly transferred to long-term memory. Therefore, it is important to get the proper amount of sleep so that memory can function at the highest level. One of the primary functions of sleep is thought to be the improvement of the consolidation of information, as several studies have demonstrated that memory depends on getting sufficient sleep between training and test. Additionally, data obtained from neuroimaging studies have shown activation patterns in the sleeping brain that mirror those recorded during the learning of tasks from the previous day, suggesting that new memories may be solidified through such rehearsal.
