In contrast to the Fed, the ECB normally does not buy bonds outright. The normal procedure used by the ECB for manipulating the money supply has been via the so-called refinancing facilities. In these facilities, bonds are not purchased but used in reverse transactions: repurchase agreements, or collateralised loans. These two transactions are similar, i.e. bonds are used as collaterals for loans, the difference being of legal nature. In the repos the ownership of the collateral changes to the ECB until the loan is repaid.
Who buys the bonds instead of using them in reverse transactions?
the Fed

Input: Middle Ages
Depopulation, deurbanisation, invasion, and movement of peoples, which had begun in Late Antiquity, continued in the Early Middle Ages. The barbarian invaders, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle Eastonce part of the Eastern Roman Empirecame under the rule of the Caliphate, an Islamic empire, after conquest by Muhammad's successors. Although there were substantial changes in society and political structures, the break with Antiquity was not complete. The still-sizeable Byzantine Empire survived in the east and remained a major power. The empire's law code, the Code of Justinian, was rediscovered in Northern Italy in 1070 and became widely admired later in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions. Monasteries were founded as campaigns to Christianise pagan Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th and early 9th century. It covered much of Western Europe, but later succumbed to the pressures of internal civil wars combined with external invasionsVikings from the north, Magyars from the east, and Saracens from the south.

In what century did the Caliphate conquer North Africa?
Output: 7th

Input: Article: Forms of corruption vary, but include bribery, extortion, cronyism, nepotism, gombeenism, parochialism patronage, influence peddling, graft, and embezzlement. Corruption may facilitate criminal enterprise such as drug trafficking, money laundering, and human trafficking, though is not restricted to these activities. Misuse of government power for other purposes, such as repression of political opponents and general police brutality, is also considered political corruption.

Now answer this question: The repression of what is also considered political corruption?

Output: political opponents

Question: What was the name of the person who published a report in the China Digital Times?
Ans: Book Blade

Here is a question about this article: In 2001, Lee was inducted into the Alabama Academy of Honor. In the same year, Chicago mayor Richard M. Daley initiated a reading program throughout the city's libraries, and chose his favorite book, To Kill a Mockingbird, as the first title of the One City, One Book program. Lee declared that "there is no greater honor the novel could receive". By 2004, the novel had been chosen by 25 communities for variations of the citywide reading program, more than any other novel. David Kipen of the National Endowment of the Arts, who supervised The Big Read, states "people just seem to connect with it. It dredges up things in their own lives, their interactions across racial lines, legal encounters, and childhood. It's just this skeleton key to so many different parts of people's lives, and they cherish it."
What is the answer to this question: By 2004, how many communities were using the book as part of their reading programs?
****
So... 25

Article: Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.

Question: Precipitation hardening alloys are sometimes also?
Ans:
heat-treatable alloys
