Q: Question: "Oracle Bone comes before modern?"  Context: "The use of such contractions is as old as Chinese characters themselves, and they have frequently been found in religious or ritual use. In the Oracle Bone script, personal names, ritual items, and even phrases such as 受又(祐) shòu yòu "receive blessings" are commonly contracted into single characters. A dramatic example is that in medieval manuscripts 菩薩 púsà "bodhisattva" (simplified: 菩萨) is sometimes written with a single character formed of a 2×2 grid of four 十 (derived from the grass radical over two 十). However, for the sake of consistency and standardization, the CPC seeks to limit the use of such polysyllabic characters in public writing to ensure that every character only has one syllable."  Answer:
A: Chinese characters

Q: Question: "How is the theory put into practice?"  Context: "Even though there is a broad scientific agreement that essentialist and typological conceptualizations of race are untenable, scientists around the world continue to conceptualize race in widely differing ways, some of which have essentialist implications. While some researchers sometimes use the concept of race to make distinctions among fuzzy sets of traits, others in the scientific community suggest that the idea of race often is used in a naive or simplistic way,[page needed] and argue that, among humans, race has no taxonomic significance by pointing out that all living humans belong to the same species, Homo sapiens, and subspecies, Homo sapiens sapiens."  Answer:
A: scientists around the world continue to conceptualize race in widely differing ways

Q: Question: "How does credit default swaps help AIG to do business?"  Context: "Another example relates to AIG, which insured obligations of various financial institutions through the usage of credit default swaps. The basic CDS transaction involved AIG receiving a premium in exchange for a promise to pay money to party A in the event party B defaulted. However, AIG did not have the financial strength to support its many CDS commitments as the crisis progressed and was taken over by the government in September 2008. U.S. taxpayers provided over $180 billion in government support to AIG during 2008 and early 2009, through which the money flowed to various counterparties to CDS transactions, including many large global financial institutions."  Answer:
A: receiving a premium in exchange for a promise to pay money to party A in the event party B defaulted

Q: Question: "Why is the nickname possibly not very valid?"  Context: "Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer."  Answer:
A:
about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer
