Problem: Vinyl's lower surface noise level than shellac was not forgotten, nor was its durability. In the late 1930s, radio commercials and pre-recorded radio programs being sent to disc jockeys started being stamped in vinyl, so they would not break in the mail. In the mid-1940s, special DJ copies of records started being made of vinyl also, for the same reason. These were all 78 rpm. During and after World War II, when shellac supplies were extremely limited, some 78 rpm records were pressed in vinyl instead of shellac, particularly the six-minute 12-inch (30 cm) 78 rpm records produced by V-Disc for distribution to United States troops in World War II. In the 1940s, radio transcriptions, which were usually on 16-inch records, but sometimes 12-inch, were always made of vinyl, but cut at 33 1⁄3 rpm. Shorter transcriptions were often cut at 78 rpm.
By the mid 1940s what was the primary material records were made of?
The answer is the following: vinyl

Problem: About that time the "executionist movement" (Polish: "egzekucja praw"--"execution of the laws") began to take form. Its members would seek to curb the power of the magnates at the Sejm and to strengthen the power of king and country.
