Input: Read this: 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.
Question: What material were most mailed records made of?

QUES: David Archuleta's performance of John Lennon's "Imagine" was considered by many as one of the best of the season. Jennifer Lopez, who was brought in as a judge in season ten, called it a beautiful song-moment that she will never forget. Jason Castro's semi-final performance of "Hallelujah" also received considerable attention, and it propelled Jeff Buckley's version of the song to the top of the Billboard digital song chart. This was the first season in which contestants' recordings were released onto iTunes after their performances, and although sales information was not released so as not to prejudice the contest, leaked information indicated that contestants' songs frequently reached the top of iTunes sales charts.
Which David Archuletta cover was thought to be the best of the season by many?

In November 1795, there was a debate in Parliament on the high price of corn and Burke wrote a memorandum to Pitt on the subject. In December Samuel Whitbread MP introduced a bill giving magistrates the power to fix minimum wages and Fox said he would vote for it. This debate probably led Burke to editing his memorandum, as there appeared a notice that Burke would soon publish a letter on the subject to the Secretary of the Board of Agriculture, Arthur Young; but he failed to complete it. These fragments were inserted into the memorandum after his death and published posthumously in 1800 as, Thoughts and Details on Scarcity. In it, Burke expounded "some of the doctrines of political economists bearing upon agriculture as a trade". Burke criticised policies such as maximum prices and state regulation of wages, and set out what the limits of government should be:

Some of the comments on YouTube make you weep for the future of humanity just for the spelling alone, never mind the obscenity and the naked hatred".
