Here is a question about this article: On April 12, 1980, a military coup led by Master Sergeant Samuel Doe of the Krahn ethnic group overthrew and killed President William R. Tolbert, Jr.. Doe and the other plotters later executed a majority of Tolbert's cabinet and other Americo-Liberian government officials and True Whig Party members. The coup leaders formed the People's Redemption Council (PRC) to govern the country. A strategic Cold War ally of the West, Doe received significant financial backing from the United States while critics condemned the PRC for corruption and political repression.
What is the answer to this question: On what date was William R. Tolbert killed?
****
So... April 12, 1980

When did the Soviet Union break up?
****
The answer: December 25, 1991

Problem: Please answer a question about the following article about Child labour:
Out of former Soviet Union republics Uzbekistan continued and expanded the program of child labour on industrial scale to increase profits on the main source of Islam Karimov's income, cotton harvesting. In September, when school normally starts, the classes are suspended and children are sent to cotton fields for work, where they are assigned daily quotas of 20 to 60 kg of raw cotton they have to collect. This process is repeated in spring, when collected cotton needs to be hoed and weeded. In 2006 it is estimated that 2.7 million children were forced to work this way.
What are the 2016 estimates for child labour in regards to cotton picking?
A: 2.7 million

Question: Read this and answer the question

Hydrogen can be prepared in several different ways, but economically the most important processes involve removal of hydrogen from hydrocarbons. Commercial bulk hydrogen is usually produced by the steam reforming of natural gas. At high temperatures (10001400 K, 7001100 C or 13002000 F), steam (water vapor) reacts with methane to yield carbon monoxide and H
2.

The most economical way to prepare hydrogen involves removing it from what?
Answer: hydrocarbons

Problem: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
What type of charge did a particle have that behaved similarly to light quantum energy?
The answer is the following: neutral

Input: Article: By the end of 2011, total renewable power capacity worldwide exceeded 1,360 GW, up 8%. Renewables producing electricity accounted for almost half of the 208 GW of capacity added globally during 2011. Wind and solar photovoltaics (PV) accounted for almost 40% and 30% . Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% electricity from wind, solar, geothermal, and biomass.

Now answer this question: Renewables contributed what percentage to our energy consumption?

Output:
19 percent
