TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What determines the model of forces?, Context: For certain physical scenarios, it is impossible to model forces as being due to gradient of potentials. This is often due to macrophysical considerations that yield forces as arising from a macroscopic statistical average of microstates. For example, friction is caused by the gradients of numerous electrostatic potentials between the atoms, but manifests as a force model that is independent of any macroscale position vector. Nonconservative forces other than friction include other contact forces, tension, compression, and drag. However, for any sufficiently detailed description, all these forces are the results of conservative ones since each of these macroscopic forces are the net results of the gradients of microscopic potentials.

SOLUTION: gradient of potentials

PROBLEM: what group is mentioned second to last?, Context: During the Republic, any person who wished to hold public office had to conform to the Reformed Church and take an oath to this effect. The extent to which different religions or denominations were persecuted depended much on the time period and regional or city leaders. In the beginning, this was especially focused on Roman Catholics, being the religion of the enemy. In 17th-century Leiden, for instance, people opening their homes to services could be fined 200 guilders (a year's wage for a skilled tradesman) and banned from the city. Throughout this, however, personal freedom of religion existed and was one factor – along with economic reasons – in causing large immigration of religious refugees from other parts of Europe.

SOLUTION: people opening their homes

PROBLEM: How many total people live in Warsaw?, Context: Warsaw (Polish: Warszawa [varˈʂava] ( listen); see also other names) is the capital and largest city of Poland. It stands on the Vistula River in east-central Poland, roughly 260 kilometres (160 mi) from the Baltic Sea and 300 kilometres (190 mi) from the Carpathian Mountains. Its population is estimated at 1.740 million residents within a greater metropolitan area of 2.666 million residents, which makes Warsaw the 9th most-populous capital city in the European Union. The city limits cover 516.9 square kilometres (199.6 sq mi), while the metropolitan area covers 6,100.43 square kilometres (2,355.39 sq mi).

SOLUTION:
2.666 million residents
