Here is a question about this article: Sugar, starch, cotton, linen, hemp, some types of rope, wood and particle boards, papyrus and paper, vegetable oils, wax, and natural rubber are examples of commercially important materials made from plant tissues or their secondary products. Charcoal, a pure form of carbon made by pyrolysis of wood, has a long history as a metal-smelting fuel, as a filter material and adsorbent and as an artist's material and is one of the three ingredients of gunpowder. Cellulose, the world's most abundant organic polymer, can be converted into energy, fuels, materials and chemical feedstock. Products made from cellulose include rayon and cellophane, wallpaper paste, biobutanol and gun cotton. Sugarcane, rapeseed and soy are some of the plants with a highly fermentable sugar or oil content that are used as sources of biofuels, important alternatives to fossil fuels, such as biodiesel.
What is the answer to this question: How is charcoal made?

So... pyrolysis of wood

Here is a question about this article: During the Eocene (56 million years ago - 33.9 million years ago), the continents continued to drift toward their present positions. At the beginning of the period, Australia and Antarctica remained connected, and warm equatorial currents mixed with colder Antarctic waters, distributing the heat around the world and keeping global temperatures high. But when Australia split from the southern continent around 45 Ma, the warm equatorial currents were deflected away from Antarctica, and an isolated cold water channel developed between the two continents. The Antarctic region cooled down, and the ocean surrounding Antarctica began to freeze, sending cold water and ice floes north, reinforcing the cooling. The present pattern of ice ages began about 40 million years ago.[citation needed]
What is the answer to this question: How long ago did Antarctica and Australia split?
****
So... around 45 Ma

Here is a question about this article: According to the Census Bureau, the median household income in 2013 was $36,836, down 7.9 percent from 2008 when the median household income was $40,008 (in 2013 dollars). For comparison, the median household income among metropolitan areas was $60,482, down 8.2 percent in the same period, and the national median household income was $55,250, down 7.0 percent from 2008. The city's wealth disparity is evident when neighborhoods are compared. Residents in Society Hill had a median household income of $93,720 while residents in one of North Philadelphia's districts reported the lowest median household income, $14,185.
What is the answer to this question: What was the median household income in 2013?
****
So...
$36,836
