Input: Article: The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.

Now answer this question: What did this new law require?

Output: all drugs introduced between 1938 and 1962 had to be effective

Input: Article: Thuringia's leading research centre is Jena, followed by Ilmenau. Both focus on technology, in particular life sciences and optics at Jena and information technology at Ilmenau. Erfurt is a centre of Germany's horticultural research, whereas Weimar and Gotha with their various archives and libraries are centres of historic and cultural research. Most of the research in Thuringia is publicly funded basic research due to the lack of large companies able to invest significant amounts in applied research, with the notable exception of the optics sector at Jena.

Now answer this question: Which universities are known for their historic and cultural aspects?

Output: Weimar and Gotha
