Input: Article: A 2011 discovery in the Canadian province of New Brunswick uncovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago. Wood can be dated by carbon dating and in some species by dendrochronology to make inferences about when a wooden object was created.

Now answer this question: How many millions of years old were the plants that were discovered in New Brunswick?

Output: 395 to 400

Article: Native Americans in the United States make up 0.97% to 2% of the population. In the 2010 census, 2.9 million people self-identified as Native American, Native Hawaiian, and Alaska Native alone, and 5.2 million people identified as U.S. Native Americans, either alone or in combination with one or more ethnicity or other races. 1.8 million are recognized as enrolled tribal members.[citation needed] Tribes have established their own criteria for membership, which are often based on blood quantum, lineal descent, or residency. A minority of US Native Americans live in land units called Indian reservations. Some California and Southwestern tribes, such as the Kumeyaay, Cocopa, Pascua Yaqui and Apache span both sides of the USMexican border. Haudenosaunee people have the legal right to freely cross the USCanadian border. Athabascan, Tlingit, Haida, Tsimshian, Inupiat, Blackfeet, Nakota, Cree, Anishinaabe, Huron, Lenape, Mi'kmaq, Penobscot, and Haudenosaunee, among others live in both Canada and the US.

Question: Where do a minority of US Native Americans live?
Ans: Indian reservations

Here is a question about this article: The reign of the Qianlong Emperor (17351796) saw the apogee and initial decline in prosperity and imperial control. The population rose to some 400 million, but taxes and government revenues were fixed at a low rate, virtually guaranteeing eventual fiscal crisis. Corruption set in, rebels tested government legitimacy, and ruling elites did not change their mindsets in the face of changes in the world system. Following the Opium War, European powers imposed unequal treaties, free trade, extraterritoriality and treaty ports under foreign control. The Taiping Rebellion (185064) and Dungan Revolt (186277) in Central Asia led to the deaths of some 20 million people. In spite of these disasters, in the Tongzhi Restoration of the 1860s, Han Chinese elites rallied to the defense of the Confucian order and the Qing rulers. The initial gains in the Self-Strengthening Movement were destroyed in the First Sino-Japanese War of 1895, in which the Qing lost its influence over Korea and the possession of Taiwan. New Armies were organized, but the ambitious Hundred Days' Reform of 1898 was turned back by Empress Dowager Cixi, a ruthless but capable leader. When, in response to the violently anti-foreign Yihetuan ("Boxers"), foreign powers invaded China, the Empress Dowager declared war on them, leading to defeat and the flight of the Imperial Court to Xi'an.
What is the answer to this question: When was the Dungan Revolt?
****
So... (186277)

The problem: Answer a question about this article:
In biology, energy is an attribute of all biological systems from the biosphere to the smallest living organism. Within an organism it is responsible for growth and development of a biological cell or an organelle of a biological organism. Energy is thus often said to be stored by cells in the structures of molecules of substances such as carbohydrates (including sugars), lipids, and proteins, which release energy when reacted with oxygen in respiration. In human terms, the human equivalent (H-e) (Human energy conversion) indicates, for a given amount of energy expenditure, the relative quantity of energy needed for human metabolism, assuming an average human energy expenditure of 12,500 kJ per day and a basal metabolic rate of 80 watts. For example, if our bodies run (on average) at 80 watts, then a light bulb running at 100 watts is running at 1.25 human equivalents (100 80) i.e. 1.25 H-e. For a difficult task of only a few seconds' duration, a person can put out thousands of watts, many times the 746 watts in one official horsepower. For tasks lasting a few minutes, a fit human can generate perhaps 1,000 watts. For an activity that must be sustained for an hour, output drops to around 300; for an activity kept up all day, 150 watts is about the maximum. The human equivalent assists understanding of energy flows in physical and biological systems by expressing energy units in human terms: it provides a "feel" for the use of a given amount of energy.
What is often said to be stored by cells in the structures of molecules of substances such as carbohydrates, lipids and proteins?

The answer: Energy

Problem: Please answer a question about the following article about PlayStation 3:
At its press conference at the 2007 Tokyo Game Show, Sony announced DualShock 3 (trademarked DUALSHOCK 3), a PlayStation 3 controller with the same function and design as Sixaxis, but with vibration capability included. Hands-on accounts describe the controller as being noticeably heavier than the standard Sixaxis controller and capable of vibration forces comparable to DualShock 2. It was released in Japan on November 11, 2007; in North America on April 5, 2008; in Australia on April 24, 2008; in New Zealand on May 9, 2008; in mainland Europe on July 2, 2008, and in the United Kingdom and Ireland on July 4, 2008.
At what event at the Tokyo Game Show was the DualShock 3 first announced?
A: press conference

Question: Read this and answer the question

ReplayGain is a standard for measuring and storing the loudness of an MP3 file (audio normalization) in its metadata tag, enabling a ReplayGain-compliant player to automatically adjust the overall playback volume for each file. MP3Gain may be used to reversibly modify files based on ReplayGain measurements so that adjusted playback can be achieved on players without ReplayGain capability.

What program can be used to modify files based on ReplayGain measurements?
Answer:
MP3Gain
