question:
How was access gained to Alaska, Context: The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, provide the subject of ongoing research and discussion. According to archaeological and genetic evidence, North and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the land bridge of Beringia that joined Siberia to north west North America (Alaska). Alaska was a glacial refugia because it had low snowfall, allowing a small population to exist. The Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska (East Beringia) for thousands of years.
answer:
the land bridge


question:
__ died in the Tower of London., Context: Various owners leased it from royal landlords and the freehold was the subject of frenzied speculation during the 17th century. By then, the old village of Eye Cross had long since fallen into decay, and the area was mostly wasteland. Needing money, James I sold off part of the Crown freehold but retained part of the site on which he established a 4-acre (16,000 m2) mulberry garden for the production of silk. (This is at the northwest corner of today's palace.) Clement Walker in Anarchia Anglicana (1649) refers to "new-erected sodoms and spintries at the Mulberry Garden at S. James's"; this suggests it may have been a place of debauchery. Eventually, in the late 17th century, the freehold was inherited from the property tycoon Sir Hugh Audley by the great heiress Mary Davies.
answer:
Clement Walker


question:
What kind of process is clemency?, Context: The legal administration of the death penalty in the United States is complex. Typically, it involves four critical steps: (1) sentencing, (2) direct review, (3) state collateral review, and (4) federal habeas corpus. Recently, a narrow and final fifth level of process – (5) the Section 1983 challenge – has become increasingly important. (Clemency or pardon, through which the Governor or President of the jurisdiction can unilaterally reduce or abrogate a death sentence, is an executive rather than judicial process.) The number of new death sentences handed down peaked in 1995–1996 (309). There were 73 new death sentences handed down in 2014, the lowest number since 1973 (44).
answer:

executive
