Factories and mines were not the only places where child labour was prevalent in the early 20th century. Home-based manufacturing across the United States and Europe employed children as well. Governments and reformers argued that labour in factories must be regulated and the state had an obligation to provide welfare for poor. Legislation that followed had the effect of moving work out of factories into urban homes. Families and women, in particular, preferred it because it allowed them to generate income while taking care of household duties.
Why would families perfer labour done at the home as opposed to the factory?
A: because it allowed them to generate income while taking care of household duties.

The location on the banks of the river Rhine allowed Utrecht to become an important trade centre in the Northern Netherlands. The growing town Utrecht was granted city rights by Henry V in 1122. When the main flow of the Rhine moved south, the old bed, which still flowed through the heart of the town became evermore canalized; and the wharf system was built as an inner city harbour system. On the wharfs storage facilities (werfkelders) were built, on top of which the main street, including houses was constructed. The wharfs and the cellars are accessible from a platform at water level with stairs descending from the street level to form a unique structure.[nb 2] The relations between the bishop, who controlled many lands outside of the city, and the citizens of Utrecht was not always easy. The bishop, for example dammed the Kromme Rijn at Wijk bij Duurstede to protect his estates from flooding. This threatened shipping for the city and led the city of Utrecht to commission a canal to ensure access to the town for shipping trade: the Vaartse Rijn, connecting Utrecht to the Hollandse IJssel at IJsselstein.
What was Utrecht granted in the 11th century?
A: unanswerable

Some 97 percent of male BYU graduates and 32 percent of female graduates took a hiatus from their undergraduate studies at one point to serve as LDS missionaries. In October 2012, the LDS Church announced at its general conference that young men could serve a mission after they turn 18 and have graduated from high school, rather than after age 19 under the old policy. Many young men would often attend a semester or two of higher education prior to beginning missionary service. This policy change will likely impact what has been the traditional incoming freshman class at BYU. Female students may now begin their missionary service anytime after turning 19, rather than age 21 under the previous policy. For males, a full-time mission is two years in length, and for females it lasts 18 months.
At what age, since 2012, are men allowed to serve a mission after high school graduation?
A: 18

While LEDs have the advantage over fluorescent lamps that they do not contain mercury, they may contain other hazardous metals such as lead and arsenic. Regarding the toxicity of LEDs when treated as waste, a study published in 2011 stated: "According to federal standards, LEDs are not hazardous except for low-intensity red LEDs, which leached Pb [lead] at levels exceeding regulatory limits (186 mg/L; regulatory limit: 5). However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), lead (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous."
According to a California study, what harmful metal is in most non-LEDs?
A:
unanswerable
