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.
What is the term for keys used for identification?
A: diagnostic keys

After the Union of Horodło the Lithuanian nobility acquired equal status with the Polish szlachta, and over time began to become more and more polonized, although they did preserve their national consciousness, and in most cases recognition of their Lithuanian family roots. In the 16th century some of the Lithuanian nobility claimed that they were of Roman extraction, and the Lithuanian language was just a morphed Latin language. This led to paradox: Polish nobility claimed own ancestry from Sarmatian tribes, but Sarmatians were considered enemies to Romans. Thus new Roman-Sarmatian theory was created. Strong cultural ties with Polish nobility led that in the 16th century the new term to name Lithuanian nobility appeared šlėkta—a direct loanword from Polish szlachta. From the view of historical truth Lithuanians also should use this term, šlėkta (szlachta), to name own nobility, but Lithuanian linguists forbade the usage of this Polish loanword. This refusal to use word szlachta (in Lithuanian text šlėkta) complicates all naming.
What is the new term used for the lithuanian nobility?
A: šlėkta

The Islamic Prophet Muhammad carried out a siege against the Banu Qaynuqa tribe known as the Invasion of Banu Qaynuqa in February 624  Muhammad ordered his followers to attack the Banu Qaynuqa Jews for allegedly breaking the treaty known as the Constitution of Medina by pinning the clothes of a Muslim woman, which led to her being stripped naked As a result, a Muslim killed a Jew in retaliation, and the Jews in turn killed the Muslim man. This escalated to a chain of revenge killings, and enmity grew between Muslims and the Banu Qaynuqa, leading to the siege of their fortress.:122 The tribe eventually surrendered to Muhammad, who initially wanted to kill the members of Banu Qaynuqa but ultimately yielded to Abdullah ibn Ubayy's insistence and agreed to expel the Qaynuqa.

The first settlement is defined as Paleapolis (Παλεάπολις), the Ancient Greek world for "old city", in order to distinguish it from a second settlement built during the 5th century BC, called Neapolis (Νεάπολις), "new city". The neapolis was erected towards the east and along with it, monumental walls around the whole settlement were built to prevent attacks from foreign threats. Some part of this structure can still be seen in the Cassaro district. This district was named after the walls themselves; the word Cassaro deriving from the Arab al-qsr (castle, stronghold). Along the walls there were few doors to access and exit the city, suggesting that trade even toward the inner part of the island occurred frequently. Moreover, according to some studies, it may be possible that there were some walls that divided the old city from the new one too. The colony developed around a central street (decumanus), cut perpendicularly by minor streets. This street today has become the Corso Vittorio Emanuele.
Which district was named for the walls surrounding it?
A:
Cassaro
