Input: Geological history of Earth
In contrast to the Proterozoic, Archean rocks are often heavily metamorphized deep-water sediments, such as graywackes, mudstones, volcanic sediments and banded iron formations. Greenstone belts are typical Archean formations, consisting of alternating high- and low-grade metamorphic rocks. The high-grade rocks were derived from volcanic island arcs, while the low-grade metamorphic rocks represent deep-sea sediments eroded from the neighboring island frogs and deposited in a forearc basin. In short, greenstone belts represent sutured protocontinents.

Low grade metamorphic rocks are composed of what, generally?
Output: deep-sea sediments

Input: Article: On January 21, 2014 IBM announced that company executives would forgo bonuses for fiscal year 2013. The move came as the firm reported a 5% drop in sales and 1% decline in net profit over 2012. It also committed to a $1.2bn plus expansion of its data center and cloud-storage business, including the development of 15 new data centers. After ten successive quarters of flat or sliding sales under Chief Executive Virginia Rometty IBM is being forced to look at new approaches. Said Rometty, "We've got to reinvent ourselves like we've done in prior generations."

Now answer this question: IBM committed to an expansion totaling this dollar amount in 2014?

Output: $1.2bn

Here is a question about this article: The governments of Australia and New Zealand responded to the 2011 fresh-water crisis by supplying temporary desalination plants, and assisted in the repair of the existing desalination unit that was donated by Japan in 2006. In response to the 2011 drought, Japan funded the purchase of a 100 m3/d desalination plant and two portable 10 m3/d plants as part of its Pacific Environment Community (PEC) program. Aid programs from the European Union and Australia also provided water tanks as part of the longer term solution for the storage of available fresh water.
What is the answer to this question: As aprt of what program did Japan fund a new desalination plant at Tuvalu?
****
So... Pacific Environment Community

The problem: Answer a question about this article:
H2 reacts with every oxidizing element. Hydrogen can react spontaneously and violently at room temperature with chlorine and fluorine to form the corresponding hydrogen halides, hydrogen chloride and hydrogen fluoride, which are also potentially dangerous acids.
What temperature does hydrogen react with these elements?
****
The answer: room temperature

The problem: Answer a question about this article:
Rather than teach small parts of a large number of subjects, Whitehead advocated teaching a relatively few important concepts that the student could organically link to many different areas of knowledge, discovering their application in actual life. For Whitehead, education should be the exact opposite of the multidisciplinary, value-free school model it should be transdisciplinary, and laden with values and general principles that provide students with a bedrock of wisdom and help them to make connections between areas of knowledge that are usually regarded as separate.
Whitehead's education style was to teach what?
****
The answer:
a relatively few important concepts
