Problem: METRO began light rail service on January 1, 2004, with the inaugural track ("Red Line") running about 8 miles (13 km) from the University of HoustonDowntown (UHD), which traverses through the Texas Medical Center and terminates at NRG Park. METRO is currently in the design phase of a 10-year expansion plan that will add five more lines. and expand the current Red Line. Amtrak, the national passenger rail system, provides service three times a week to Houston via the Sunset Limited (Los AngelesNew Orleans), which stops at a train station on the north side of the downtown area. The station saw 14,891 boardings and alightings in fiscal year 2008. In 2012, there was a 25 percent increase in ridership to 20,327 passengers embarking from the Houston Amtrak station.
When did Houston start using light rail lines?
The answer is the following: January 1, 2004

Various models of climate change have been projected into the 22nd century for the Alps, with an expectation that a trend toward increased temperatures will have an effect on snowfall, snowpack, glaciation, and river runoff.
What will have an effect on snowfall, snowpack, glaciation, and river runoff?
increased temperatures

Input: War on Terror
In a major split in the ranks of Al Qaeda's organization, the Iraqi franchise, known as Al Qaeda in Iraq covertly invaded Syria and the Levant and began participating in the ongoing Syrian Civil War, gaining enough support and strength to re-invade Iraq's western provinces under the name of the Islamic State of Iraq and the Levant (ISIS/ISIL), taking over much of the country in a blitzkrieg-like action and combining the Iraq insurgency and Syrian Civil War into a single conflict. Due to their extreme brutality and a complete change in their overall ideology, Al Qaeda's core organization in Central Asia eventually denounced ISIS and directed their affiliates to cut off all ties with this organization. Many analysts[who?] believe that because of this schism, Al Qaeda and ISIL are now in a competition to retain the title of the world's most powerful terrorist organization.

With support from Syrians, what did the Iraq branch of Al Qaeda rename themselves to?
Output: Islamic State of Iraq and the Levant (ISIS/ISIL)

Input: Article: From November 17, 1947 to December 23, 1947, John Bardeen and Walter Brattain at AT&T's Bell Labs in the United States performed experiments and observed that when two gold point contacts were applied to a crystal of germanium, a signal was produced with the output power greater than the input. Solid State Physics Group leader William Shockley saw the potential in this, and over the next few months worked to greatly expand the knowledge of semiconductors. The term transistor was coined by John R. Pierce as a contraction of the term transresistance. According to Lillian Hoddeson and Vicki Daitch, authors of a biography of John Bardeen, Shockley had proposed that Bell Labs' first patent for a transistor should be based on the field-effect and that he be named as the inventor. Having unearthed Lilienfeld's patents that went into obscurity years earlier, lawyers at Bell Labs advised against Shockley's proposal because the idea of a field-effect transistor that used an electric field as a "grid" was not new. Instead, what Bardeen, Brattain, and Shockley invented in 1947 was the first point-contact transistor. In acknowledgement of this accomplishment, Shockley, Bardeen, and Brattain were jointly awarded the 1956 Nobel Prize in Physics "for their researches on semiconductors and their discovery of the transistor effect."

Now answer this question: Why was the term transistor used?

Output: a contraction of the term transresistance

Article: The new head of state, Ibrahim Babangida, declared himself president and commander in chief of the armed forces and the ruling Supreme Military Council. He set 1990 as the official deadline for a return to democratic governance. Babangida's tenure was marked by a flurry of political activity: he instituted the International Monetary Fund's Structural Adjustment Program (SAP) to aid in the repayment of the country's crushing international debt, which most federal revenue was dedicated to servicing. He enrolled Nigeria in the Organisation of the Islamic Conference, which aggravated religious tensions in the country.

Question: What did Babangida set up to help pay Nigeria's national debt?
Ans: International Monetary Fund's Structural Adjustment Program

Input: Modern history
Over the course of the 20th century, the world's per-capita gross domestic product grew by a factor of five, much more than all earlier centuries combined (including the 19th with its Industrial Revolution). Many economists make the case that this understates the magnitude of growth, as many of the goods and services consumed at the end of the 20th century, such as improved medicine (causing world life expectancy to increase by more than two decades) and communications technologies, were not available at any price at its beginning. However, the gulf between the world's rich and poor grew wider, and the majority of the global population remained in the poor side of the divide.

What has Modern medicine increased the average life expectancy by?
Output:
two decades
