Problem: Comparsas are held throughout the week, consisting of large groups "of dancers dancing and traveling on the streets, followed by a Carrosa (carriage) where the musicians play. The Comparsa is a development of African processions where groups of devotees follow a given saint or deity during a particular religious celebration".

This simply means that a mixture of water paint and water or raw eggs is used to paint people on the streets, the goal being to paint as many people as you can".

During the 18th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters. The choice and sequence of the characters may be artificial in keys designed purely for identification (diagnostic keys) or more closely related to the natural or phyletic order of the taxa in synoptic keys. By the 18th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide. In 1753 Carl von Linné (Carl Linnaeus) published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature. This established a standardised binomial or two-part naming scheme where the first name represented the genus and the second identified the species within the genus. For the purposes of identification, Linnaeus's Systema Sexuale classified plants into 24 groups according to the number of their male sexual organs. The 24th group, Cryptogamia, included all plants with concealed reproductive parts, mosses, liverworts, ferns, algae and fungi.
How are the plants classified?
number of their male sexual organs


Input: Ottoman Empire
With Constantinople as its capital and control of lands around the Mediterranean basin, the Ottoman Empire was at the centre of interactions between the Eastern and Western worlds for six centuries. Following a long period of military setbacks against European powers, the Ottoman Empire gradually declined into the late nineteenth century. The empire allied with Germany in the early 20th century, with the imperial ambition of recovering its lost territories, joining in World War I to achieve this ambition on the side of Germany and the Central Powers. While the Empire was able to largely hold its own during the conflict, it was struggling with internal dissent, especially with the Arab Revolt in its Arabian holdings. Starting before the war, but growing increasingly common and violent during it, major atrocities were committed by the Ottoman government against the Armenians, Assyrians and Pontic Greeks. The Empire's defeat and the occupation of part of its territory by the Allied Powers in the aftermath of World War I resulted in the emergence of a new state, Turkey, in the Ottoman Anatolian heartland following the Turkish War of Independence, as well as the founding of modern Balkan and Middle Eastern states and the partitioning of the Ottoman Empire.

When did the Ottoman empire decline?
Output: into the late nineteenth century
