Here is a question about this article: As female fetuses have two X chromosomes and male ones a XY pair, the chromosome Y is the responsible for producing male differentiation on the defect female development. The differentiation process is driven by androgen hormones, mainly testosterone and dihydrotestosterone (DHT). The newly formed testicles in the fetus are responsible for the secretion of androgens, that will cooperate in driving the sexual differentiation of the developing fetus, included its brain. This results in sexual differences between males and females. This fact has led some scientists to test in various ways the result of modifying androgen exposure levels in mammals during fetus and early life.
What is the answer to this question: What results in sexual differences in males and females?
****
So... secretion of androgens, that will cooperate in driving the sexual differentiation of the developing fetus, included its brain


Here is a question about this article: The U.S. Financial Crisis Inquiry Commission reported its findings in January 2011. It concluded that "the crisis was avoidable and was caused by: widespread failures in financial regulation, including the Federal Reserve’s failure to stem the tide of toxic mortgages; dramatic breakdowns in corporate governance including too many financial firms acting recklessly and taking on too much risk; an explosive mix of excessive borrowing and risk by households and Wall Street that put the financial system on a collision course with crisis; key policy makers ill prepared for the crisis, lacking a full understanding of the financial system they oversaw; and systemic breaches in accountability and ethics at all levels".
What is the answer to this question: Who was not prepared for the financial crisis in 2007 by lacking a full understanding of the financial system?
****
So... key policy makers


Here is a question about this article: Genetic studies on Ashkenazim have been conducted to determine how much of their ancestry comes from the Levant, and how much derives from European populations. These studies—researching both their paternal and maternal lineages—point to a significant prevalence of ancient Levantine origins. But they have arrived at diverging conclusions regarding both the degree and the sources of their European ancestry. These diverging conclusions focus particularly on the extent of the European genetic origin observed in Ashkenazi maternal lineages.
What is the answer to this question: Have studies on the genetics of the Ashkenazim come to similar or divergent conclusions regarding the degree and sources of their European ancestry?
****
So...
they have arrived at diverging conclusions
