Input: Article: Some experiments on very resinous Longleaf Pine specimens indicate an increase in strength, due to the resin which increases the strength when dry. Such resin-saturated heartwood is called "fat lighter". Structures built of fat lighter are almost impervious to rot and termites; however they are very flammable. Stumps of old longleaf pines are often dug, split into small pieces and sold as kindling for fires. Stumps thus dug may actually remain a century or more since being cut. Spruce impregnated with crude resin and dried is also greatly increased in strength thereby.

Now answer this question: What is fat lighter practically impervious to in addition to termites?

Output: rot


Article: Like any plucked instrument, mandolin notes decay to silence rather than sound out continuously as with a bowed note on a violin, and mandolin notes decay faster than larger stringed instruments like the guitar. This encourages the use of tremolo (rapid picking of one or more pairs of strings) to create sustained notes or chords. The mandolin's paired strings facilitate this technique: the plectrum (pick) strikes each of a pair of strings alternately, providing a more full and continuous sound than a single string would.

Question: What is tremolo?
Ans: rapid picking of one or more pairs of strings


Here is a question about this article: About 1.7 to 5 billion cases of diarrhea occur per year. It is most common in developing countries, where young children get diarrhea on average three times a year. Total deaths from diarrhea are estimated at 1.26 million in 2013 – down from 2.58 million in 1990. In 2012, it is the second most common cause of deaths in children younger than five (0.76 million or 11%). Frequent episodes of diarrhea are also a common cause of malnutrition and the most common cause in those younger than five years of age. Other long term problems that can result include stunted growth and poor intellectual development.
What is the answer to this question: HOw many cases of diarrhea are there a year?
****
So... 1.7 to 5 billion cases


The problem: Answer a question about this article:
Antibacterial antibiotics are commonly classified based on their mechanism of action, chemical structure, or spectrum of activity. Most target bacterial functions or growth processes. Those that target the bacterial cell wall (penicillins and cephalosporins) or the cell membrane (polymyxins), or interfere with essential bacterial enzymes (rifamycins, lipiarmycins, quinolones, and sulfonamides) have bactericidal activities. Those that target protein synthesis (macrolides, lincosamides and tetracyclines) are usually bacteriostatic (with the exception of bactericidal aminoglycosides). Further categorization is based on their target specificity. "Narrow-spectrum" antibacterial antibiotics target specific types of bacteria, such as Gram-negative or Gram-positive bacteria, whereas broad-spectrum antibiotics affect a wide range of bacteria. Following a 40-year hiatus in discovering new classes of antibacterial compounds, four new classes of antibacterial antibiotics have been brought into clinical use in the late 2000s and early 2010s: cyclic lipopeptides (such as daptomycin), glycylcyclines (such as tigecycline), oxazolidinones (such as linezolid), and lipiarmycins (such as fidaxomicin).
What do anitibiotics mostly target?
****
The answer: bacterial functions or growth processes


Problem: Please answer a question about the following article about Multiracial American:
Racial discrimination continued to be enacted in new laws in the 20th century, for instance the one-drop rule was enacted in Virginia's 1924 Racial Integrity Law and in other southern states, in part influenced by the popularity of eugenics and ideas of racial purity. People buried fading memories that many whites had multiracial ancestry. Many families were multiracial. Similar laws had been proposed but not passed in the late nineteenth century in South Carolina and Virginia, for instance. After regaining political power in Southern states by disenfranchising blacks, white Democrats passed laws to impose Jim Crow and racial segregation to restore white supremacy. They maintained these until forced to change in the 1960s and after by enforcement of federal legislation authorizing oversight of practices to protect the constitutional rights of African Americans and other minority citizens.
When did Virginia add the one drop rule to their laws?
A: 1924


Question: Read this and answer the question

It combined the high speed of electronics with the ability to be programmed for many complex problems. It could add or subtract 5000 times a second, a thousand times faster than any other machine. It also had modules to multiply, divide, and square root. High speed memory was limited to 20 words (about 80 bytes). Built under the direction of John Mauchly and J. Presper Eckert at the University of Pennsylvania, ENIAC's development and construction lasted from 1943 to full operation at the end of 1945. The machine was huge, weighing 30 tons, using 200 kilowatts of electric power and contained over 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductors.

Where did John Mauchly and J. Presper Eckert build the ENIAC?
Answer:
University of Pennsylvania
