Problem: Separation of powers under the United States Constitution:

The Chief Justice presides in the Senate during a president's impeachment trial. The rules of the Senate, however, generally do not grant much authority to the presiding officer. Thus, the Chief Justice's role in this regard is a limited one.

Who has an unlimited role in this regard?
---
A: unanswerable

Problem: Orthodox Judaism:

In practice, the emphasis on strictness has resulted in the rise of "homogeneous enclaves" with other haredi Jews that are less likely to be threatened by assimilation and intermarriage, or even to interact with other Jews who do not share their doctrines. Nevertheless, this strategy has proved successful and the number of adherents to Orthodox Judaism, especially Haredi and Chassidic communities, has grown rapidly. Some scholars estimate more Jewish men are studying in yeshivot (Talmudic schools) and Kollelim (post-graduate Talmudical colleges for married (male) students) than at any other time in history.[citation needed]

What resulted in the rise of heterogeneous enclaves?
---
A: unanswerable

Problem: Alps:

The Alps are a source of minerals that have been mined for thousands of years. In the 8th to 6th centuries BC during the Hallstatt culture, Celtic tribes mined copper; later the Romans mined gold for coins in the Bad Gastein area. Erzberg in Styria furnishes high-quality iron ore for the steel industry. Crystals are found throughout much of the Alpine region such as cinnabar, amethyst, and quartz. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments.

The cinnabar deposits are found in what area?
---
A: Slovenia

Problem: Electric motor:

All the electromagnetic motors, and that includes the types mentioned here derive the torque from the vector product of the interacting fields. For calculating the torque it is necessary to know the fields in the air gap . Once these have been established by mathematical analysis using FEA or other tools the torque may be calculated as the integral of all the vectors of force multiplied by the radius of each vector. The current flowing in the winding is producing the fields and for a motor using a magnetic material the field is not linearly proportional to the current. This makes the calculation difficult but a computer can do the many calculations needed.

What needs to be known to calculate torque?
---
A:
fields in the air gap
