Input: Article: Article 10 of the Berne Convention mandates that national laws provide for limitations to copyright, so that copyright protection does not extend to certain kinds of uses that fall under what the treaty calls "fair practice," including but not limited to minimal quotations used in journalism and education. The laws implementing these limitations and exceptions for uses that would otherwise be infringing broadly fall into the categories of either fair use or fair dealing. In common law systems, these fair practice statutes typically enshrine principles underlying many earlier judicial precedents, and are considered essential to freedom of speech.

Now answer this question: What are these statutes essential to?

Output: freedom of speech

Input: Article: Charles Pollak (born Karol Pollak), the inventor of the first electrolytic capacitors, found out that the oxide layer on an aluminum anode remained stable in a neutral or alkaline electrolyte, even when the power was switched off. In 1896 he filed a patent for an "Electric liquid capacitor with aluminum electrodes." Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.

Now answer this question: Who invented the first electrolytic capacitor?

Output:
Charles Pollak
