The collateralized debt obligation in particular enabled financial institutions to obtain investor funds to finance subprime and other lending, extending or increasing the housing bubble and generating large fees. This essentially places cash payments from multiple mortgages or other debt obligations into a single pool from which specific securities draw in a specific sequence of priority. Those securities first in line received investment-grade ratings from rating agencies. Securities with lower priority had lower credit ratings but theoretically a higher rate of return on the amount invested.

What securities had lower credit ratings but potentially a higher rate of return?
Output: Securities with lower priority

Input: Antarctica
In 1983, the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. A coalition of international organizations launched a public pressure campaign to prevent any minerals development in the region, led largely by Greenpeace International, which established its own scientific stationWorld Park Basein the Ross Sea region and conducted annual expeditions to document environmental effects of humans on Antarctica. In 1988, the Convention on the Regulation of Antarctic Mineral Resources (CRAMRA) was adopted. The following year, however, Australia and France announced that they would not ratify the convention, rendering it dead for all intents and purposes. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. The Protocol on Environmental Protection to the Antarctic Treaty (the "Madrid Protocol") was negotiated as other countries followed suit and on 14 January 1998 it entered into force. The Madrid Protocol bans all mining in Antarctica, designating Antarctica a "natural reserve devoted to peace and science".

What was the alternate treaty offered by Australia and France?
Output: Madrid Protocol

Input: Oklahoma
The western edge of the Oklahoma panhandle is out of alignment with its Texas border. The Oklahoma/New Mexico border is actually 2.1 to 2.2 miles east of the Texas line. The border between Texas and New Mexico was set first as a result of a survey by Spain in 1819. It was then set along the 103rd Meridian. In the 1890s, when Oklahoma was formally surveyed using more accurate surveying equipment and techniques, it was discovered that the Texas line was not set along the 103rd Meridian. Surveying techniques were not as accurate in 1819, and the actual 103rd Meridian was approximately 2.2 miles to the east. It was much easier to leave the mistake as it was than for Texas to cede land to New Mexico to correct the original surveying error. The placement of the Oklahoma/New Mexico border represents the true 103rd Meridian.

When was the border between TX and NM first determined?
Output: 1819
