Input: Article: The most impressive and famous of Sumerian buildings are the ziggurats, large layered platforms which supported temples. Sumerian cylinder seals also depict houses built from reeds not unlike those built by the Marsh Arabs of Southern Iraq until as recently as 400 CE.

Sumerian temples and palaces made use of more advanced materials and techniques,[citation needed] such as buttresses, recesses, half columns, and clay nails.

Input: Article: In Europe, Dutch is the majority language in the Netherlands (96%) and Belgium (59%) as well as a minority language in Germany and northern France's French Flanders, where it is in the ultimate stage of language death. Though Belgium as a whole is multilingual, the two regions into which the country is divided (Flanders, francophone Wallonia, bilingual Brussels and small 'facility' zones) are largely monolingual. The Netherlands and Belgium produce the vast majority of music, films, books and other media written or spoken in Dutch. Dutch is a monocentric language, with all speakers using the same standard form (authorized by the Dutch Language Union) based on a Dutch orthography employing the Latin alphabet when writing. In stark contrast to its written uniformity, Dutch lacks a prestige dialect and has a large dialectal continuum consisting of 28 main dialects, which can themselves be further divided into at least 600 distinguishable varieties.

Now answer this question: What percentage of people in Belgium speak Dutch?

Output:
59%
