Student A:Context: Post-glacial rebound (also called either isostatic rebound or crustal rebound) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostatic depression. Post-glacial rebound and isostatic depression are different parts of a process known as either glacial isostasy, glacial isostatic adjustment, or glacioisostasy. Glacioisostasy is the solid Earth deformation associated with changes in ice mass distribution. The most obvious and direct effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through processes known as ocean siphoning and continental levering, the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.

Student A:Radio personality, television producer and Chamber member Johnny Grant is generally credited with implementing the changes that resuscitated the Walk and established it as a significant tourist attraction. Beginning in 1968, he stimulated publicity and encouraged international press coverage by requiring that each recipient personally attend his or her star's unveiling ceremony. Grant later recalled that "it was tough to get people to come accept a star" until the neighborhood finally began its recovery in the 1980s. In 1980 he instituted a fee of $2,500, payable by the person or entity nominating the recipient, to fund the Walk of Fame's upkeep and minimize further taxpayer burden. The fee has increased incrementally over time; by 2002 it had reached $15,000, and stood at $30,000 in 2012. The current (2017) fee is $40,000.

At its founding, the UN had 51 member states; there are now 193. The headquarters of the UN is in Manhattan, New York City, and is subject to extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict. The UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organization in the world.
