Extract the answer to the question from the following context. Question: What did the UNICEF study find? Context: Concerns have often been raised over the buying public's moral complicity in purchasing products assembled or otherwise manufactured in developing countries with child labour. However, others have raised concerns that boycotting products manufactured through child labour may force these children to turn to more dangerous or strenuous professions, such as prostitution or agriculture. For example, a UNICEF study found that after the Child Labour Deterrence Act was introduced in the US, an estimated 50,000 children were dismissed from their garment industry jobs in Bangladesh, leaving many to resort to jobs such as "stone-crushing, street hustling, and prostitution", jobs that are "more hazardous and exploitative than garment production". The study suggests that boycotts are "blunt instruments with long-term consequences, that can actually harm rather than help the children involved."

Extract the answer to the question from the following context. Question: What type of media did Norte Dame have for those who listened to news on ear buds but not visually Context: As at most other universities, Notre Dame's students run a number of news media outlets. The nine student-run outlets include three newspapers, both a radio and television station, and several magazines and journals. Begun as a one-page journal in September 1876, the Scholastic magazine is issued twice monthly and claims to be the oldest continuous collegiate publication in the United States. The other magazine, The Juggler, is released twice a year and focuses on student literature and artwork. The Dome yearbook is published annually. The newspapers have varying publication interests, with The Observer published daily and mainly reporting university and other news, and staffed by students from both Notre Dame and Saint Mary's College. Unlike Scholastic and The Dome, The Observer is an independent publication and does not have a faculty advisor or any editorial oversight from the University. In 1987, when some students believed that The Observer began to show a conservative bias, a liberal newspaper, Common Sense was published. Likewise, in 2003, when other students believed that the paper showed a liberal bias, the conservative paper Irish Rover went into production. Neither paper is published as often as The Observer; however, all three are distributed to all students. Finally, in Spring 2008 an undergraduate journal for political science research, Beyond Politics, made its debut.

Extract the answer to the question from the following context. Question: What was an issue? Context: A PM motor does not have a field winding on the stator frame, instead relying on PMs to provide the magnetic field against which the rotor field interacts to produce torque. Compensating windings in series with the armature may be used on large motors to improve commutation under load. Because this field is fixed, it cannot be adjusted for speed control. PM fields (stators) are convenient in miniature motors to eliminate the power consumption of the field winding. Most larger DC motors are of the "dynamo" type, which have stator windings. Historically, PMs could not be made to retain high flux if they were disassembled; field windings were more practical to obtain the needed amount of flux. However, large PMs are costly, as well as dangerous and difficult to assemble; this favors wound fields for large machines.
