Input: Read this: In infrared photography, infrared filters are used to capture the near-infrared spectrum. Digital cameras often use infrared blockers. Cheaper digital cameras and camera phones have less effective filters and can "see" intense near-infrared, appearing as a bright purple-white color. This is especially pronounced when taking pictures of subjects near IR-bright areas (such as near a lamp), where the resulting infrared interference can wash out the image. There is also a technique called 'T-ray' imaging, which is imaging using far-infrared or terahertz radiation. Lack of bright sources can make terahertz photography more challenging than most other infrared imaging techniques. Recently T-ray imaging has been of considerable interest due to a number of new developments such as terahertz time-domain spectroscopy.
Question: What is another name for terahertz radiation?

Output: far-infrared

QUES: Victoria wrote to her uncle Leopold, whom Victoria considered her "best and kindest adviser", to thank him "for the prospect of great happiness you have contributed to give me, in the person of dear Albert ... He possesses every quality that could be desired to render me perfectly happy. He is so sensible, so kind, and so good, and so amiable too.

QUES: The Cambrian is a major division of the geologic timescale that begins about 541.0 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.
What were the continents of the Cambrian area believed to have formerly been a part of?

ANS: Pannotia

Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. The city was originally laid out in a grid pattern with the North Carolina State Capitol in Union Square at the center. In the United States Civil War the city was spared from any significant battle, only falling in the closing days of the war, though it did not escape the economic hardships that plagued the rest of the American South during the Reconstruction Era. The twentieth century saw the opening of the Research Triangle Park in 1959, and with the jobs it created the region and city saw a large influx of population, making it one of the fastest growing communities in the United States by the early 21st century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year did Research Triangle Park close?
Ah, so.. unanswerable

Question: The Valencia Metro derailment occurred on 3 July 2006 at 1 pm. CEST (1100 UTC) between Jesus and Placa d'Espanya stations on Line 1 of the Metrovalencia mass transit system. 43 people were killed and more than ten were seriously injured. It was not immediately clear what caused the crash. Both the Valencian government spokesman Vicente Rambla and Mayor Rita Barbera called the accident a "fortuitous" event. However, the trade union CC.OO. accused the authorities of "rushing" to say anything but admit that Line 1 is in a state of "constant deterioration" with a "failure to carry out maintenance".
Try to answer this question if possible: How many people died when the Valencia metro derailed?
Answer: 43

Question: On 21 December 2011 the bank instituted a programme of making low-interest loans with a term of three years (36 months) and 1% interest to European banks accepting loans from the portfolio of the banks as collateral. Loans totalling 489.2 bn (US$640 bn) were announced. The loans were not offered to European states, but government securities issued by European states would be acceptable collateral as would mortgage-backed securities and other commercial paper that can be demonstrated to be secure. The programme was announced on 8 December 2011 but observers were surprised by the volume of the loans made when it was implemented. Under its LTRO it loaned 489bn to 523 banks for an exceptionally long period of three years at a rate of just one percent. The by far biggest amount of 325bn was tapped by banks in Greece, Ireland, Italy and Spain. This way the ECB tried to make sure that banks have enough cash to pay off 200bn of their own maturing debts in the first three months of 2012, and at the same time keep operating and loaning to businesses so that a credit crunch does not choke off economic growth. It also hoped that banks would use some of the money to buy government bonds, effectively easing the debt crisis.
