Problem: Electric motor:

Stepper motors can be rotated to a specific angle in discrete steps with ease, and hence stepper motors are used for read/write head positioning in computer floppy diskette drives. They were used for the same purpose in pre-gigabyte era computer disk drives, where the precision and speed they offered was adequate for the correct positioning of the read/write head of a hard disk drive. As drive density increased, the precision and speed limitations of stepper motors made them obsolete for hard drives—the precision limitation made them unusable, and the speed limitation made them uncompetitive—thus newer hard disk drives use voice coil-based head actuator systems. (The term "voice coil" in this connection is historic; it refers to the structure in a typical (cone type) loudspeaker. This structure was used for a while to position the heads. Modern drives have a pivoted coil mount; the coil swings back and forth, something like a blade of a rotating fan. Nevertheless, like a voice coil, modern actuator coil conductors (the magnet wire) move perpendicular to the magnetic lines of force.)

To what device does the term, "voice coil" historically refer?

A: the structure in a typical (cone type) loudspeaker


Problem: Mexico City:

Mexico City has numerous museums dedicated to art, including Mexican colonial, modern and contemporary art, and international art. The Museo Tamayo was opened in the mid-1980s to house the collection of international contemporary art donated by famed Mexican (born in the state of Oaxaca) painter Rufino Tamayo. The collection includes pieces by Picasso, Klee, Kandinsky, Warhol and many others, though most of the collection is stored while visiting exhibits are shown. The Museo de Arte Moderno (Museum of Modern Art) is a repository of Mexican artists from the 20th century, including Rivera, Orozco, Siqueiros, Kahlo, Gerzso, Carrington, Tamayo, among others, and also regularly hosts temporary exhibits of international modern art. In southern Mexico City, the Museo Carrillo Gil (Carrillo Gil Museum) showcases avant-garde artists, as does the University Museum/Contemporary Art (Museo Universitario Arte Contemporáneo – or MUAC), designed by famed Mexican architect Teodoro González de León, inaugurated in late 2008.

When was the Museo Tamayo opened?

A: mid-1980s


Problem: Child labour:

On 23 June 1757, the English East India Company defeated Siraj-ud-Daula, the Nawab of Bengal, in the Battle of Plassey. The British thus became masters of east India (Bengal, Bihar, Orissa) – a prosperous region with a flourishing agriculture, industry and trade. This led to a large amount of children being forced into labour due to the increasing need of cheap labour to produce large numbers of goods. Many multinationals often employed children because that they can be recruited for less pay, and have more endurance to utilise in factory environments. Another reason many Indian children were hired was because they lack knowledge of their basic rights, they did not cause trouble or complain, and they were often more trustworthy. The innocence that comes with childhood was utilised to make a profit by many and was encouraged by the need for family income.

How did India child workers act?
---
A: they did not cause trouble or complain


Problem: Orthodox Judaism:

Orthodox Judaism collectively considers itself the only true heir to the Jewish tradition. The Orthodox Jewish movements consider all non-Orthodox Jewish movements to be unacceptable deviations from authentic Judaism; both because of other denominations' doubt concerning the verbal revelation of Written and Oral Torah, and because of their rejection of Halakhic precedent as binding. As such, Orthodox Jewish groups characterize non-Orthodox forms of Judaism as heretical; see the article on Relationships between Jewish religious movements.

What do Orthodox Jewish movements consider all other non-orthodox moments?
---
A:
unacceptable
