Problem: Track lighting, invented by Lightolier, was popular at one period of time because it was much easier to install than recessed lighting, and individual fixtures are decorative and can be easily aimed at a wall. It has regained some popularity recently in low-voltage tracks, which often look nothing like their predecessors because they do not have the safety issues that line-voltage systems have, and are therefore less bulky and more ornamental in themselves. A master transformer feeds all of the fixtures on the track or rod with 12 or 24 volts, instead of each light fixture having its own line-to-low voltage transformer. There are traditional spots and floods, as well as other small hanging fixtures. A modified version of this is cable lighting, where lights are hung from or clipped to bare metal cables under tension.
What type of lighting uses lights that are hung or clipped to bare metal cables?
The answer is the following: cable lighting

Scientists have been studying the impact of climate change and water use. For example, each year more water is diverted from rivers for snowmaking in the ski resorts, the effect of which is yet unknown. Furthermore, the decrease of glaciated areas combined with a succession of winters with lower-than-expected precipitation may have a future impact on the rivers in the Alps as well as an effect on the water availability to the lowlands.

Input: Namibia
Compared to neighbouring countries, Namibia has a large degree of media freedom. Over the past years, the country usually ranked in the upper quarter of the Press Freedom Index of Reporters without Borders, reaching position 21 in 2010, being on par with Canada and the best-positioned African country. The African Media Barometer shows similarly positive results.[citation needed] However, as in other countries, there is still mentionable influence of representatives of state and economy on media in Namibia. In 2009, Namibia dropped to position 36 on the Press Freedom Index. In 2013, it was 19th. In 2014 it ranked 22nd

Where was Namibia ranked on Press Freedom in 2014?
Output: 22nd

Input: Article: Manhattan was on track to have an estimated 90,000 hotel rooms at the end of 2014, a 10% increase from 2013. In October 2014, the Anbang Insurance Group, based in China, purchased the Waldorf Astoria New York for US$1.95 billion, making it the world's most expensive hotel ever sold.

Now answer this question: The Waldorf Astoria hotel sold for how many dollars?

Output: 1.95 billion

Article: The Central Bank of Liberia is responsible for printing and maintaining the Liberian dollar, which is the primary form of currency in Liberia. Liberia is one of the world's poorest countries, with a formal employment rate of 15%. GDP per capita peaked in 1980 at US$496, when it was comparable to Egypt's (at the time). In 2011, the country's nominal GDP was US$1.154 billion, while nominal GDP per capita stood at US$297, the third-lowest in the world. Historically, the Liberian economy has depended heavily on foreign aid, foreign direct investment and exports of natural resources such as iron ore, rubber and timber.

Question: What does Liberia's economy heavily depends on?
Ans: foreign aid

Input: Antarctica
Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. In the Eocene epoch, about 40 Ma Australia-New Guinea separated from Antarctica, so that latitudinal currents could isolate Antarctica from Australia, and the first ice began to appear. During the EoceneOligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm and had been decreasing from earlier levels in the thousands of ppm.

When did Australia separate from Antarctica?
Output:
Eocene epoch
