The period between the foundation of the Han dynasty and Wang Mang's reign is known as the Western Han dynasty (simplified Chinese: ; traditional Chinese: ; pinyin: Xi Han) or Former Han dynasty (simplified Chinese: ; traditional Chinese: ; pinyin: Qianhan) (206 BC 9 AD). During this period the capital was at Chang'an (modern Xi'an). From the reign of Guangwu the capital was moved eastward to Luoyang. The era from his reign until the fall of Han is known as the Eastern Han dynasty (simplified Chinese: ; traditional Chinese: ; pinyin: Dong Han) or the Later Han dynasty (simplified Chinese: ; traditional Chinese: ; pinyin: Hou Han) (25220 AD).

Where was the capital located during the Western Han dynasty?
Answer: Chang'an

Problem: Plants synthesize a number of unique polymers like the polysaccharide molecules cellulose, pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin, a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when a plant sucks water through them under water stress. Lignin is also used in other cell types like sclerenchyma fibers that provide structural support for a plant and is a major constituent of wood. Sporopollenin is a chemically resistant polymer found in the outer cell walls of spores and pollen of land plants responsible for the survival of early land plant spores and the pollen of seed plants in the fossil record. It is widely regarded as a marker for the start of land plant evolution during the Ordovician period. The concentration of carbon dioxide in the atmosphere today is much lower than it was when plants emerged onto land during the Ordovician and Silurian periods. Many monocots like maize and the pineapple and some dicots like the Asteraceae have since independently evolved pathways like Crassulacean acid metabolism and the C4 carbon fixation pathway for photosynthesis which avoid the losses resulting from photorespiration in the more common C3 carbon fixation pathway. These biochemical strategies are unique to land plants.
What polymer is found in spores and pollen?
The answer is the following: Sporopollenin

The name Nigeria was taken from the Niger River running through the country. This name was allegedly coined in the late 19th century by British journalist Flora Shaw, she was inspired by the name of the river, in preference to terms such as "Central Sudan". The origin of the name ''Nigeria'' came from the name of the Niger River. The word ( Niger ) is an alteration of the Tuareg name egerew n-igerewen used by inhabitants along the middle reaches of the river around Timbuktu prior to 19th-century European colonialism. Egerew n-igerewen means River of the Rivers.
Which river reaches Timbuktu?
Niger

Input: Somalis
According to mtDNA studies by Holden (2005) and Richards et al. (2006), a significant proportion of the maternal lineages of Somalis consists of the M1 haplogroup. This mitochondrial clade is common among Ethiopians and North Africans, particularly Egyptians and Algerians. M1 is believed to have originated in Asia, where its parent M clade represents the majority of mtDNA lineages. This haplogroup is also thought to possibly correlate with the Afro-Asiatic language family:

What family of languages is the M1 haplogroup associated with?
Output: Afro-Asiatic

Input: Article: The album garnered critical acclaim. Ray of Light was honored with four Grammy Awards. In 2003, Slant Magazine called it "one of the great pop masterpieces of the '90s" and Rolling Stone listed it among "The 500 Greatest Albums of All Time". Commercially, the album peaked at number one in numerous countries and sold more than 16 million copies worldwide. The album's first single, "Frozen", became Madonna's first single to debut at number one in the UK, while in the U.S. it became her sixth number-two single, setting another record for Madonna as the artist with the most number two hits. The second single, "Ray of Light", debuted at number five on the Billboard Hot 100.

Now answer this question: How many albums did Ray of Light sell worldwide?

Output: 16 million copies

Problem: Further along these lines, The ethical problems brought up by IP rights are most pertinent when it is socially valuable goods like life-saving medicines are given IP protection. While the application of IP rights can allow companies to charge higher than the marginal cost of production in order to recoup the costs of research and development, the price may exclude from the market anyone who cannot afford the cost of the product, in this case a life-saving drug. "An IPR driven regime is therefore not a regime that is conductive to the investment of R&D of products that are socially valuable to predominately poor populations".:11089
For what type of goods are IP's ethical problems most pertinent?
The answer is the following:
socially valuable
