Please answer this: Extract the answer to the question from the following context. Question: The improvement of the damping of spurious resonances can be attributed to what? Context: Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances. Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around 1930 and the velocity or ribbon microphone in 1932. Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications.

Answer: Magnetic pickups became more common and were better designed

Problem: Extract the answer to the question from the following context. Question: When are the oldest fossils of placental animals from? Context: Recent molecular phylogenetic studies suggest that most placental orders diverged about 100 to 85 million years ago and that modern families appeared in the period from the late Eocene through the Miocene. But paleontologists object that no placental fossils have been found from before the end of the Cretaceous. The earliest undisputed fossils of placentals come from the early Paleocene, after the extinction of the dinosaurs. In particular, scientists have recently identified an early Paleocene animal named Protungulatum donnae as one of the first placental mammals. The earliest known ancestor of primates is Archicebus achilles from around 55 million years ago. This tiny primate weighed 2030 grams (0.71.1 ounce) and could fit within a human palm.

A: early Paleocene

Problem: Given the question: Extract the answer to the question from the following context. Question: What is one the key factors in corruption in societies? Context: Corruption facilitates environmental destruction. While corrupt societies may have formal legislation to protect the environment, it cannot be enforced if officials can easily be bribed. The same applies to social rights worker protection, unionization prevention, and child labor. Violation of these laws rights enables corrupt countries to gain illegitimate economic advantage in the international market.

The answer is:
officials can easily be bribed

input question: Extract the answer to the question from the following context. Question: What did his father want? Context: Since there were few posts in Hungary for mathematicians, and those were not well-paid, his father wanted von Neumann to follow him into industry and therefore invest his time in a more financially useful endeavor than mathematics. So it was decided that the best career path was to become a chemical engineer. This was not something that von Neumann had much knowledge of, so it was arranged for him to take a two-year non-degree course in chemistry at the University of Berlin, after which he sat the entrance exam to the prestigious ETH Zurich, which he passed in September 1923. At the same time, von Neumann also entered Pazmany Peter University in Budapest, as a Ph.D. candidate in mathematics. For his thesis, he chose to produce an axiomatization of Cantor's set theory. He passed his final examinations for his Ph.D. soon after graduating from ETH Zurich in 1926. He then went to the University of Gottingen on a grant from the Rockefeller Foundation to study mathematics under David Hilbert.???

Extract the answer to the question from the following context. Question: What is a treaty that doesn't require accompanying laws? Context: Treaties may be seen as 'self-executing', in that merely becoming a party puts the treaty and all of its obligations in action. Other treaties may be non-self-executing and require 'implementing legislation'a change in the domestic law of a state party that will direct or enable it to fulfill treaty obligations. An example of a treaty requiring such legislation would be one mandating local prosecution by a party for particular crimes.

Answer: self-executing

Q: Extract the answer to the question from the following context. Question: What was the first step Russia took toward an autonomous model? Context: The post-Imperial nature of Russian subdivision of government changed towards a generally autonomous model which began with the establishment of the USSR (of which Russia was governed as part). It was liberalized in the aftermath of the Soviet Union, with the reforms under Boris Yeltsin preserving much of the Soviet structure while applying increasingly liberal reforms to the governance of the constituent republics and subjects (while also coming into conflict with Chechen secessionist rebels during the Chechen War). Some of the reforms under Yeltsin were scaled back by Vladimir Putin.
A:
the establishment of the USSR
