Input: Article: In other cities, class conflict was more evident. Over a quarter of London's population had left the city by November 1940. Civilians left for more remote areas of the country. Upsurges in population south Wales and Gloucester intimated where these displaced people went. Other reasons, including industry dispersal may have been a factor. However, resentment of rich self-evacuees or hostile treatment of poor ones were signs of persistence of class resentments although these factors did not appear to threaten social order. The total number of evacuees numbered 1.4 million, including a high proportion from the poorest inner-city families. Reception committees were completely unprepared for the condition of some of the children. Far from displaying the nation's unity in time of war, the scheme backfired, often aggravating class antagonism and bolstering prejudice about the urban poor. Within four months, 88% of evacuated mothers, 86% of small children, and 43% of school children had been returned home. The lack of bombing in the Phoney War contributed significantly to the return of people to the cities, but class conflict was not eased a year later when evacuation operations had to be put into effect again.

Now answer this question: How much of the population returned in four months?

Output: 88% of evacuated mothers, 86% of small children, and 43% of school children


Article: Her Diamond Jubilee in 2012 marked 60 years on the throne, and celebrations were held throughout her realms, the wider Commonwealth, and beyond. In a message released on Accession Day, she stated: "In this special year, as I dedicate myself anew to your service, I hope we will all be reminded of the power of togetherness and the convening strength of family, friendship and good neighbourliness ... I hope also that this Jubilee year will be a time to give thanks for the great advances that have been made since 1952 and to look forward to the future with clear head and warm heart". She and her husband undertook an extensive tour of the United Kingdom, while her children and grandchildren embarked on royal tours of other Commonwealth states on her behalf. On 4 June, Jubilee beacons were lit around the world. On 18 December, she became the first British sovereign to attend a peacetime Cabinet meeting since George III in 1781.

Question: How many years has Elizabeth been Queen?
Ans: 60 years


Here is a question about this article: In winter, the Piedmont is colder than the coast, with temperatures usually averaging in the upper 40s–lower 50s °F (8–12 °C) during the day and often dropping below the freezing point at night. The region averages around 3–5 in (8–13 cm) of snowfall annually in the Charlotte area, and slightly more north toward the Virginia border. The Piedmont is especially notorious for sleet and freezing rain. Freezing rain can be heavy enough to snarl traffic and break down trees and power lines. Annual precipitation and humidity are lower in the Piedmont than in the mountains or the coast, but even at its lowest, the average is 40 in (1,020 mm) per year.
What is the answer to this question: What do the temperatures often drop to at night in the piedmont region in the winter?
****
So... below the freezing point


The problem: Answer a question about this article:
LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
Zener diodes below what voltage are not widely available?
****
The answer: 3 V


Problem: Please answer a question about the following article about Georgian architecture:
In the early decades of the twentieth century when there was a growing nostalgia for its sense of order, the style was revived and adapted and in the United States came to be known as the Colonial Revival. In Canada the United Empire Loyalists embraced Georgian architecture as a sign of their fealty to Britain, and the Georgian style was dominant in the country for most of the first half of the 19th century. The Grange, for example, a manor built in Toronto, was built in 1817. In Montreal, English born architect John Ostell worked on a significant number of remarkable constructions in the Georgian style such as the Old Montreal Custom House and the Grand séminaire de Montréal.
What Toronto building was built in 1817?
A: The Grange


Question: Read this and answer the question

Humans regard certain insects as pests, and attempt to control them using insecticides and a host of other techniques. Some insects damage crops by feeding on sap, leaves or fruits. A few parasitic species are pathogenic. Some insects perform complex ecological roles; blow-flies, for example, help consume carrion but also spread diseases. Insect pollinators are essential to the life-cycle of many flowering plant species on which most organisms, including humans, are at least partly dependent; without them, the terrestrial portion of the biosphere (including humans) would be devastated. Many other insects are considered ecologically beneficial as predators and a few provide direct economic benefit. Silkworms and bees have been used extensively by humans for the production of silk and honey, respectively. In some cultures, people eat the larvae or adults of certain insects.

By what method do humans often try to control the spread of insects?
Answer:
insecticides
