Please answer this: Extract the answer to the question from the following context. Question: When did China start to suffer overpopulation? Context: China also began suffering from mounting overpopulation during this period. Population growth was stagnant for the first half of the 17th century due to civil wars and epidemics, but prosperity and internal stability gradually reversed this trend. The introduction of new crops from the Americas such as the potato and peanut allowed an improved food supply as well, so that the total population of China during the 18th century ballooned from 100 million to 300 million people. Soon all available farmland was used up, forcing peasants to work ever-smaller and more intensely worked plots. The Qianlong Emperor once bemoaned the country's situation by remarking "The population continues to grow, but the land does not." The only remaining part of the empire that had arable farmland was Manchuria, where the provinces of Jilin and Heilongjiang had been walled off as a Manchu homeland. The emperor decreed for the first time that Han Chinese civilians were forbidden to settle. Mongols were forbidden by the Qing from crossing the borders of their banners, even into other Mongol Banners and from crossing into neidi (the Han Chinese 18 provinces) and were given serious punishments if they did in order to keep the Mongols divided against each other to benefit the Qing.

Please answer this: Extract the answer to the question from the following context. Question: What was spawned from the next group of values? Context: A number of parties have collected survey data, from the public and from experts, to try and gauge the level of corruption and bribery, as well as its impact on political and economic outcomes. A second wave of corruption metrics has been created by Global Integrity, the International Budget Partnership, and many lesser known local groups. These metrics include the Global Integrity Index, first published in 2004. These second wave projects aim to create policy change by identifying resources more effectively and creating checklists toward incremental reform. Global Integrity and the International Budget Partnership each dispense with public surveys and instead uses in-country experts to evaluate "the opposite of corruption" – which Global Integrity defines as the public policies that prevent, discourage, or expose corruption. These approaches compliment the first wave, awareness-raising tools by giving governments facing public outcry a checklist which measures concrete steps toward improved governance.

Please answer this: Extract the answer to the question from the following context. Question: Of the works discussed, which title was written earliest? Context: Later Indian materialist Jayaraashi Bhatta (6th century) in his work Tattvopaplavasimha ("The upsetting of all principles") refuted the Nyaya Sutra epistemology. The materialistic Cārvāka philosophy appears to have died out some time after 1400. When Madhavacharya compiled Sarva-darśana-samgraha (a digest of all philosophies) in the 14th century, he had no Cārvāka/Lokāyata text to quote from, or even refer to.
