Article: Since before 2000 BC, humans have utilized pesticides to protect their crops. The first known pesticide was elemental sulfur dusting used in ancient Sumer about 4,500 years ago in ancient Mesopotamia. The Rig Veda, which is about 4,000 years old, mentions the use of poisonous plants for pest control. By the 15th century, toxic chemicals such as arsenic, mercury, and lead were being applied to crops to kill pests. In the 17th century, nicotine sulfate was extracted from tobacco leaves for use as an insecticide. The 19th century saw the introduction of two more natural pesticides, pyrethrum, which is derived from chrysanthemums, and rotenone, which is derived from the roots of tropical vegetables. Until the 1950s, arsenic-based pesticides were dominant. Paul Müller discovered that DDT was a very effective insecticide. Organochlorines such as DDT were dominant, but they were replaced in the U.S. by organophosphates and carbamates by 1975. Since then, pyrethrin compounds have become the dominant insecticide. Herbicides became common in the 1960s, led by "triazine and other nitrogen-based compounds, carboxylic acids such as 2,4-dichlorophenoxyacetic acid, and glyphosate".

Question: What decade did herbicides become common?
Ans: 1960s


Here is a question about this article: 10th Street (40°44′03″N 74°00′11″W﻿ / ﻿40.7342580°N 74.0029670°W﻿ / 40.7342580; -74.0029670) begins at the FDR Drive and Avenue C. West of Sixth Avenue, it turns southward about 40 degrees to join the Greenwich Village street grid and continue to West Street on the Hudson River. Because West 4th Street turns northward at Sixth Avenue, it intersects 10th, 11th and 12th and 13th Streets in the West Village. The M8 bus operates on 10th Street in both directions between Avenue D and Avenue A, and eastbound between West Street and Sixth Avenue. 10th Street has an eastbound bike lane from West Street to the East River. In 2009, the two-way section of 10th Street between Avenue A and the East River had bicycle markings and sharrows installed, but it still has no dedicated bike lane. West 10th Street was previously named Amos Street for Richard Amos. The end of West 10th Street toward the Hudson River was once the home of Newgate Prison, New York City's first prison and the United States' second.
What is the answer to this question: Does the two-way section of 10th Street have a dedicated bike lane?
****
So... no


The problem: Answer a question about this article:
The term "great power" was first used to represent the most important powers in Europe during the post-Napoleonic era. The "Great Powers" constituted the "Concert of Europe" and claimed the right to joint enforcement of the postwar treaties. The formalization of the division between small powers and great powers came about with the signing of the Treaty of Chaumont in 1814. Since then, the international balance of power has shifted numerous times, most dramatically during World War I and World War II. While some nations are widely considered to be great powers, there is no definitive list of them. In literature, alternative terms for great power are often world power or major power, but these terms can also be interchangeable with superpower.
What is another term for Great Power?
****
The answer: superpower


Problem: Please answer a question about the following article about Muammar Gaddafi:
In 1977, Gaddafi dissolved the Republic and created a new socialist state, the Jamahiriya ("state of the masses"). Officially adopting a symbolic role in governance, he retained power as military commander-in-chief and head of the Revolutionary Committees responsible for policing and suppressing opponents. Overseeing unsuccessful border conflicts with Egypt and Chad, Gaddafi's support for foreign militants and alleged responsibility for the Lockerbie bombing led to Libya's label of "international pariah". A particularly hostile relationship developed with the United States and United Kingdom, resulting in the 1986 U.S. bombing of Libya and United Nations-imposed economic sanctions. Rejecting his earlier ideological commitments, from 1999 Gaddafi encouraged economic privatization and sought rapprochement with Western nations, also embracing Pan-Africanism and helping to establish the African Union. Amid the Arab Spring, in 2011 an anti-Gaddafist uprising led by the National Transitional Council (NTC) broke out, resulting in the Libyan Civil War. NATO intervened militarily on the side of the NTC, bringing about the government's downfall. Retreating to Sirte, Gaddafi was captured and killed by NTC militants.
In what year did Gaddafi found the Jamahiriya?
A: 1977

This battle is commemorated at River Raisin National Battlefield Park south of Detroit in Monroe County. Detroit was finally recaptured by the United States later that year.

In which battle did American troops suffer the highest casualties?
Answer: Battle of Frenchtown


Religious Jews have Minhagim, customs, in addition to Halakha, or religious law, and different interpretations of law. Different groups of religious Jews in different geographic areas historically adopted different customs and interpretations. On certain issues, Orthodox Jews are required to follow the customs of their ancestors, and do not believe they have the option of picking and choosing. For this reason, observant Jews at times find it important for religious reasons to ascertain who their household's religious ancestors are in order to know what customs their household should follow. These times include, for example, when two Jews of different ethnic background marry, when a non-Jew converts to Judaism and determines what customs to follow for the first time, or when a lapsed or less observant Jew returns to traditional Judaism and must determine what was done in his or her family's past. In this sense, "Ashkenazic" refers both to a family ancestry and to a body of customs binding on Jews of that ancestry. Reform Judaism, which does not necessarily follow those minhagim, did nonetheless originate among Ashkenazi Jews.
Reform Judaism originated among what type of Jew?
Ashkenazi Jews
