Problem: According to some estimates about 20% of the population lives on less than US$1.25 per day. Migration from Tajikistan and the consequent remittances have been unprecedented in their magnitude and economic impact. In 2010, remittances from Tajik labour migrants totaled an estimated $2.1 billion US dollars, an increase from 2009. Tajikistan has achieved transition from a planned to a market economy without substantial and protracted recourse to aid (of which it by now receives only negligible amounts), and by purely market-based means, simply by exporting its main commodity of comparative advantage — cheap labor. The World Bank Tajikistan Policy Note 2006 concludes that remittances have played an important role as one of the drivers of Tajikistan's robust economic growth during the past several years, have increased incomes, and as a result helped significantly reduce poverty.
What is the average amount lived on per day?
The answer is the following: US$1.25 per day

Problem: 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 differentiation process driven by?
The answer is the following: androgen hormones,

Problem: When Emperor Kammu moved the capital to Heian-kyō (Kyōto), which remained the imperial capital for the next 1,000 years, he did so not only to strengthen imperial authority but also to improve his seat of government geopolitically. Nara was abandoned after only 70 years in part due to the ascendancy of Dōkyō and the encroaching secular power of the Buddhist institutions there. Kyōto had good river access to the sea and could be reached by land routes from the eastern provinces. The early Heian period (784–967) continued Nara culture; the Heian capital was patterned on the Chinese Tang capital at Chang'an, as was Nara, but on a larger scale than Nara. Kammu endeavoured to improve the Tang-style administrative system which was in use. Known as the ritsuryō, this system attempted to recreate the Tang imperium in Japan, despite the "tremendous differences in the levels of development between the two countries". Despite the decline of the Taika-Taihō reforms, imperial government was vigorous during the early Heian period. Indeed, Kammu's avoidance of drastic reform decreased the intensity of political struggles, and he became recognized as one of Japan's most forceful emperors.
Kanmu modeled his government after what Chinese capital?
The answer is the following: Tang

Problem: Starting in 2002, Apple moved to eliminate CRT displays from its product line as part of aesthetic design and space-saving measures with the iMac G4. However, the new iMac with its flexible LCD flat-panel monitor was considerably more expensive on its debut than the preceding iMac G3, largely due to the higher cost of the LCD technology at the time. In order to keep the Macintosh affordable for the education market and due to obsolescence of the iMac G3, Apple created the eMac in April 2002 as the intended successor; however the eMac's CRT made it relatively bulky and somewhat outdated, while its all-in-one construction meant it could not be expanded to meet consumer demand for larger monitors. The iMac G4's relatively high prices were approaching that of laptops which were portable and had higher resolution LCD screens. Meanwhile, Windows PC manufacturers could offer desktop configurations with LCD flat panel monitors at prices comparable to the eMac and at much lower cost than the iMac G4. The flop of the Power Mac G4 Cube, along with the more expensive iMac G4 and heavy eMac, meant that Macintosh desktop sales never reached the market share attained by the previous iMac G3. For the next half-decade while Macintosh sales held steady, it would instead be the iPod portable music player and iTunes music download service that would drive Apple's sales growth.
What was the main problem with the eMac's CRT?
The answer is the following:
relatively bulky and somewhat outdated
