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.
Why were new plants arriving in Europe in the 18th century?
****
The answer: newly discovered countries

Videoconferencing provides students with the opportunity to learn by participating in two-way communication forums. Furthermore, teachers and lecturers worldwide can be brought to remote or otherwise isolated educational facilities. Students from diverse communities and backgrounds can come together to learn about one another, although language barriers will continue to persist. Such students are able to explore, communicate, analyze and share information and ideas with one another. Through videoconferencing, students can visit other parts of the world to speak with their peers, and visit museums and educational facilities. Such virtual field trips can provide enriched learning opportunities to students, especially those in geographically isolated locations, and to the economically disadvantaged. Small schools can use these technologies to pool resources and provide courses, such as in foreign languages, which could not otherwise be offered.
What is a major barrier to videoconferencing between some communities?
****
The answer: language

The most common staple crops consumed during Han were wheat, barley, foxtail millet, proso millet, rice, and beans. Commonly eaten fruits and vegetables included chestnuts, pears, plums, peaches, melons, apricots, strawberries, red bayberries, jujubes, calabash, bamboo shoots, mustard plant and taro. Domesticated animals that were also eaten included chickens, Mandarin ducks, geese, cows, sheep, pigs, camels and dogs (various types were bred specifically for food, while most were used as pets). Turtles and fish were taken from streams and lakes. Commonly hunted game, such as owl, pheasant, magpie, sika deer, and Chinese bamboo partridge were consumed. Seasonings included sugar, honey, salt and soy sauce. Beer and wine were regularly consumed.
What type of partridge was commonly consumed?
****
The answer: Chinese bamboo

In response to attribution of recent climate change, the City of Melbourne, in 2002, set a target to reduce carbon emissions to net zero by 2020 and Moreland City Council established the Zero Moreland program, however not all metropolitan municipalities have followed, with the City of Glen Eira notably deciding in 2009 not to become carbon neutral. Melbourne has one of the largest urban footprints in the world due to its low density housing, resulting in a vast suburban sprawl, with a high level of car dependence and minimal public transport outside of inner areas. Much of the vegetation within the city are non-native species, most of European origin, and in many cases plays host to invasive species and noxious weeds. Significant introduced urban pests include the common myna, feral pigeon, brown rat, European wasp, common starling and red fox. Many outlying suburbs, particularly towards the Yarra Valley and the hills to the north-east and east, have gone for extended periods without regenerative fires leading to a lack of saplings and undergrowth in urbanised native bushland. The Department of Sustainability and Environment partially addresses this problem by regularly burning off. Several national parks have been designated around the urban area of Melbourne, including the Mornington Peninsula National Park, Port Phillip Heads Marine National Park and Point Nepean National Park in the south east, Organ Pipes National Park to the north and Dandenong Ranges National Park to the east. There are also a number of significant state parks just outside Melbourne. Responsibility for regulating pollution falls under the jurisdiction of the EPA Victoria and several local councils. Air pollution, by world standards, is classified as being good. Summer and autumn are the worst times of year for atmospheric haze in the urban area.
In what year did Melbourne set a target to reduce carbon emissions to net zero?
****
The answer:
2002
