Problem: Zinc chloride is often added to lumber as a fire retardant and can be used as a wood preservative. It is also used to make other chemicals. Zinc methyl (Zn(CH3)
2) is used in a number of organic syntheses. Zinc sulfide (ZnS) is used in luminescent pigments such as on the hands of clocks, X-ray and television screens, and luminous paints. Crystals of ZnS are used in lasers that operate in the mid-infrared part of the spectrum. Zinc sulfate is a chemical in dyes and pigments. Zinc pyrithione is used in antifouling paints.
Where is zinc pyrithion used?
The answer is the following: antifouling paints.


Worldwide consumption of paper has risen by 400% in the past 40 years leading to increase in deforestation, with 35% of harvested trees being used for paper manufacture. Most paper companies also plant trees to help regrow forests. Logging of old growth forests accounts for less than 10% of wood pulp, but is one of the most controversial issues.
What percentage of wood pulp comes from old-growth trees?
10%


Input: Nintendo Entertainment System
The NES Test Station's front features a Game Pak slot and connectors for testing various components (AC adapter, RF switch, Audio/Video cable, NES Control Deck, accessories and games), with a centrally-located selector knob to chose which component to test. The unit itself weighs approximately 11.7 pounds without a TV. It connects to a television via a combined A/V and RF Switch cable. By actuating the green button, a user can toggle between an A/V Cable or RF Switch connection. The television it is connected to (typically 11" to 14") is meant to be placed atop it.

How large was the typical television recommended for the device?
Output: typically 11" to 14"


Input: Article: To maintain a high constant body temperature is energy expensive – mammals therefore need a nutritious and plentiful diet. While the earliest mammals were probably predators, different species have since adapted to meet their dietary requirements in a variety of ways. Some eat other animals – this is a carnivorous diet (and includes insectivorous diets). Other mammals, called herbivores, eat plants. A herbivorous diet includes subtypes such as fruit-eating and grass-eating. An omnivore eats both prey and plants. Carnivorous mammals have a simple digestive tract, because the proteins, lipids, and minerals found in meat require little in the way of specialized digestion. Plants, on the other hand, contain complex carbohydrates, such as cellulose. The digestive tract of an herbivore is therefore host to bacteria that ferment these substances, and make them available for digestion. The bacteria are either housed in the multichambered stomach or in a large cecum. The size of an animal is also a factor in determining diet type. Since small mammals have a high ratio of heat-losing surface area to heat-generating volume, they tend to have high energy requirements and a high metabolic rate. Mammals that weigh less than about 18 oz (500 g) are mostly insectivorous because they cannot tolerate the slow, complex digestive process of a herbivore. Larger animals, on the other hand, generate more heat and less of this heat is lost. They can therefore tolerate either a slower collection process (those that prey on larger vertebrates) or a slower digestive process (herbivores). Furthermore, mammals that weigh more than 18 oz (500 g) usually cannot collect enough insects during their waking hours to sustain themselves. The only large insectivorous mammals are those that feed on huge colonies of insects (ants or termites).

Now answer this question: What do the majority of mammals under 18 oz eat?

Output: insects


Article: Residents of Oklahoma City suffered substantial losses on April 19, 1995 when Timothy McVeigh detonated a bomb in front of the Murrah building. The building was destroyed (the remnants of which had to be imploded in a controlled demolition later that year), more than 100 nearby buildings suffered severe damage, and 168 people were killed. The site has been commemorated as the Oklahoma City National Memorial and Museum. Since its opening in 2000, over three million people have visited. Every year on April 19, survivors, families and friends return to the memorial to read the names of each person lost.

Question: What year did the memorial first opened?
Ans: 2000


Input: Georgian architecture
Georgian architecture was widely disseminated in the English colonies during the Georgian era. American buildings of the Georgian period were very often constructed of wood with clapboards; even columns were made of timber, framed up, and turned on an over-sized lathe. At the start of the period the difficulties of obtaining and transporting brick or stone made them a common alternative only in the larger cities, or where they were obtainable locally. Dartmouth College, Harvard University, and the College of William and Mary, offer leading examples of Georgian architecture in the Americas.

What was difficult to obtain and transport during the Georgian period?
Output:
brick or stone
