Problem: Electric motor:

Nothing in the principle of any of the motors described above requires that the iron (steel) portions of the rotor actually rotate. If the soft magnetic material of the rotor is made in the form of a cylinder, then (except for the effect of hysteresis) torque is exerted only on the windings of the electromagnets. Taking advantage of this fact is the coreless or ironless DC motor, a specialized form of a PM DC motor. Optimized for rapid acceleration, these motors have a rotor that is constructed without any iron core. The rotor can take the form of a winding-filled cylinder, or a self-supporting structure comprising only the magnet wire and the bonding material. The rotor can fit inside the stator magnets; a magnetically soft stationary cylinder inside the rotor provides a return path for the stator magnetic flux. A second arrangement has the rotor winding basket surrounding the stator magnets. In that design, the rotor fits inside a magnetically soft cylinder that can serve as the housing for the motor, and likewise provides a return path for the flux.

What forms can the rotor take?
---
A: winding-filled cylinder, or a self-supporting structure


Problem: Some federal constitutions also provide that certain constitutional amendments cannot occur without the unanimous consent of all states or of a particular state. The US constitution provides that no state may be deprived of equal representation in the senate without its consent. In Australia, if a proposed amendment will specifically impact one or more states, then it must be endorsed in the referendum held in each of those states. Any amendment to the Canadian constitution that would modify the role of the monarchy would require unanimous consent of the provinces. The German Basic Law provides that no amendment is admissible at all that would abolish the federal system.
The US Constitution says what to amendments?

Answer: provides that no state may be deprived of equal representation in the senate without its consent


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The unicameral legislature (the Fono) consists of 49 members serving 5-year terms. Forty-seven are matai title-holders elected from territorial districts by Samoans; the other two are chosen by non-Samoans with no chiefly affiliation on separate electoral rolls. Universal suffrage was adopted in 1990, but only chiefs (matai) may stand for election to the Samoan seats. There are more than 25,000 matais in the country, about 5% of whom are women. The prime minister, chosen by a majority in the Fono, is appointed by the head of state to form a government. The prime minister's choices for the 12 cabinet positions are appointed by the head of state, subject to the continuing confidence of the Fono.
What do Samoans call their legislative body?
A: the Fono


Context and question: Phonology also includes topics such as phonotactics (the phonological constraints on what sounds can appear in what positions in a given language) and phonological alternation (how the pronunciation of a sound changes through the application of phonological rules, sometimes in a given order which can be feeding or bleeding,) as well as prosody, the study of suprasegmentals and topics such as stress and intonation.
Phonotactics, phonological alternation and stress are topics contained in what discipline?
Answer: unanswerable


Question: Despite trading for pitcher Matt Garza and signing free-agent slugger Carlos Peña, the Cubs finished the 2011 season 20 games under .500 with a record of 71-91. Weeks after the season came to an end, the club was rejuvenated in the form of a new philosophy, as new owner Tom Ricketts signed Theo Epstein away from the Boston Red Sox, naming him club President and giving him a five-year contract worth over $18 million, and subsequently discharged manager Mike Quade. Epstein, a proponent of sabremetrics and one of the architects of two world series titles in Boston brought along Jed Hoyer to fill the role of GM and hired Dale Sveum as manager. Although the team had a dismal 2012 season, losing 101 games (the worst record since 1966) it was largely expected. The youth movement ushered in by Epstein and Hoyer began as longtime fan favorite Kerry Wood retired in May, followed by Ryan Dempster and Geovany Soto being traded to Texas at the All-Star break for a group of minor league prospects headlined by Christian Villanueva. The development of Castro, Anthony Rizzo, Darwin Barney, Brett Jackson and pitcher Jeff Samardzija as well as the replenishing of the minor-league system with prospects such as Javier Baez, Albert Almora, and Jorge Soler became the primary focus of the season, a philosophy which the new management said would carry over at least through the 2013 season.
Is there an answer to this question: How much was the contract given to Theo Epstein worth?

Answer: $18 million


Question: Lie groups are of fundamental importance in modern physics: Noether's theorem links continuous symmetries to conserved quantities. Rotation, as well as translations in space and time are basic symmetries of the laws of mechanics. They can, for instance, be used to construct simple models—imposing, say, axial symmetry on a situation will typically lead to significant simplification in the equations one needs to solve to provide a physical description.v[›] Another example are the Lorentz transformations, which relate measurements of time and velocity of two observers in motion relative to each other. They can be deduced in a purely group-theoretical way, by expressing the transformations as a rotational symmetry of Minkowski space. The latter serves—in the absence of significant gravitation—as a model of space time in special relativity. The full symmetry group of Minkowski space, i.e. including translations, is known as the Poincaré group. By the above, it plays a pivotal role in special relativity and, by implication, for quantum field theories. Symmetries that vary with location are central to the modern description of physical interactions with the help of gauge theory.
Is there an answer to this question: What measures the time and velocity of two observers?

Answer:
unanswerable
