Brass, which is an alloy of copper and zinc, has been used since at least the 10th century BC in Judea and by the 7th century BC in Ancient Greece. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century. The mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What early process was used to dissolve zinc?
Ah, so.. unanswerable

Problem: Political parties, still called factions by some, especially those in the governmental apparatus, are lobbied vigorously by organizations, businesses and special interest groups such as trade unions. Money and gifts-in-kind to a party, or its leading members, may be offered as incentives. Such donations are the traditional source of funding for all right-of-centre cadre parties. Starting in the late 19th century these parties were opposed by the newly founded left-of-centre workers' parties. They started a new party type, the mass membership party, and a new source of political fundraising, membership dues.
What do special interest groups receive for paying membership dues?
