Input: Read this: Of numerous relationships between male slaveholders, overseers, or master's sons and women slaves, the most notable is likely that of President Thomas Jefferson with his slave Sally Hemings. As noted in the 2012 collaborative Smithsonian-Monticello exhibit, Slavery at Monticello: The Paradox of Liberty, Jefferson, then a widower, took Hemings as his concubine for nearly 40 years. They had six children of record; four Hemings children survived into adulthood, and he freed them all, among the very few slaves he freed. Two were allowed to "escape" to the North in 1822, and two were granted freedom by his will upon his death in 1826. Seven-eighths white by ancestry, all four of his Hemings children moved to northern states as adults; three of the four entered the white community, and all their descendants identified as white. Of the descendants of Madison Hemings, who continued to identify as black, some in future generations eventually identified as white and "married out", while others continued to identify as African American. It was socially advantageous for the Hemings children to identify as white, in keeping with their appearance and the majority proportion of their ancestry. Although born into slavery, the Hemings children were legally white under Virginia law of the time.

Input: Read this: The financial crisis was not widely predicted by mainstream economists except Raghuram Rajan, who instead spoke of the Great Moderation. A number of heterodox economists predicted the crisis, with varying arguments. Dirk Bezemer in his research credits (with supporting argument and estimates of timing) 12 economists with predicting the crisis: Dean Baker (US), Wynne Godley (UK), Fred Harrison (UK), Michael Hudson (US), Eric Janszen (US), Steve Keen (Australia), Jakob Brøchner Madsen & Jens Kjaer Sørensen (Denmark), Kurt Richebächer (US), Nouriel Roubini (US), Peter Schiff (US), and Robert Shiller (US). Examples of other experts who gave indications of a financial crisis have also been given. Not surprisingly, the Austrian economic school regarded the crisis as a vindication and classic example of a predictable credit-fueled bubble that could not forestall the disregarded but inevitable effect of an artificial, manufactured laxity in monetary supply, a perspective that even former Fed Chair Alan Greenspan in Congressional testimony confessed himself forced to return to.
Question: How did the Austrian economic school regard the crisis?

Output: as a vindication


Input: Read this: Between January and May 1673, the Dutch East India Company forcibly took the island, before English reinforcements restored English East India Company control. The company experienced difficulty attracting new immigrants, and sentiments of unrest and rebellion fomented among the inhabitants. Ecological problems, including deforestation, soil erosion, vermin and drought, led Governor Isaac Pyke to suggest in 1715 that the population be moved to Mauritius, but this was not acted upon and the company continued to subsidise the community because of the island's strategic location. A census in 1723 recorded 1,110 people, including 610 slaves.
Question: What did the English East India Company have difficulty attracting?

Output: new immigrants


Input: Read this: Yale seniors at graduation smash clay pipes underfoot to symbolize passage from their "bright college years," though in recent history the pipes have been replaced with "bubble pipes". ("Bright College Years," the University's alma mater, was penned in 1881 by Henry Durand, Class of 1881, to the tune of Die Wacht am Rhein.) Yale's student tour guides tell visitors that students consider it good luck to rub the toe of the statue of Theodore Dwight Woolsey on Old Campus. Actual students rarely do so. In the second half of the 20th century Bladderball, a campus-wide game played with a large inflatable ball, became a popular tradition but was banned by administration due to safety concerns. In spite of administration opposition, students revived the game in 2009, 2011, and 2014, but its future remains uncertain.
Question: What do juniors crush to celebrate graduation?
