Context and question: Critics such as economist Paul Krugman and U.S. Treasury Secretary Timothy Geithner have argued that the regulatory framework did not keep pace with financial innovation, such as the increasing importance of the shadow banking system, derivatives and off-balance sheet financing. A recent OECD study suggest that bank regulation based on the Basel accords encourage unconventional business practices and contributed to or even reinforced the financial crisis. In other cases, laws were changed or enforcement weakened in parts of the financial system. Key examples include:
Which group's study suggested that Basel accords encourage unconventional business practices?
Answer: OECD
Context and question: Interspecific crop diversity is, in part, responsible for offering variety in what we eat. Intraspecific diversity, the variety of alleles within a single species, also offers us choice in our diets. If a crop fails in a monoculture, we rely on agricultural diversity to replant the land with something new. If a wheat crop is destroyed by a pest we may plant a hardier variety of wheat the next year, relying on intraspecific diversity. We may forgo wheat production in that area and plant a different species altogether, relying on interspecific diversity. Even an agricultural society which primarily grows monocultures, relies on biodiversity at some point.
What has some responsibility for offering variety in monoculture?
Answer: unanswerable
Context and question: The most important demographic influence in the modern Portuguese seems to be the oldest one; current interpretation of Y-chromosome and mtDNA data suggests that the Portuguese have their origin in Paleolithic peoples that began arriving to the European continent around 45,000 years ago. All subsequent migrations did leave an impact, genetically and culturally, but the main population source of the Portuguese is still Paleolithic. Genetic studies show Portuguese populations not to be significantly different from other European populations.
What is the main population source of the Portuguese people?
Answer:
Paleolithic
