Question: What level of classification are both Combretum and Astragalus?
Context: The Manual Ability Classification System (MACS) is a medical classification system used to describe how children aged from 4 to 18 years old with cerebral palsy use their hands with objects during activities of daily living, with a focus on the use of both hands together.  Like the Gross Motor Function Classification System (GMFCS), there are five levels - level I being the least impaired, only finding difficulty in tasks needing speed and accuracy, and level V being the most impaired, not being able to handle objects and having severely limited abilities for even simple actions. Wachau is one of Austria's most established and notable wine regions, specializing in dry wines made from Riesling and Grüner Veltliner.  Located in Lower Austria along the Danube, west of Vienna and Krems an der Donau, it is one of the westernmost wine producing regions in Austria with only a few scattered plantings in Tyrol being further west.  While most of Austria follows a wine classification systems based on ripeness and harvest must weight that parallels the German wine classification system, Wachau wines have a unique classification system.  The three classification levels for Wachau wine include "Steinfeder" for wines up to 11.5% alcohol level, "Federspiel" for wines between 11.5–12.5% and "Smaragd" that must have a minimum of 12.5% alcohol level.  Despite its renown, the Wachau is a small wine region that usually accounts for only around 3% of Austria's wine production. Astragalus is a large genus of about 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae.  It is the largest genus of plants in terms of described species.  The genus is native to temperate regions of the Northern Hemisphere.  Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ("A. gummifer", "A. tragacanthus").  Some pale-flowered vetches are similar in appearance, but vetches are more vine-like. Gara-Gel State Reserve or Qaragol State Reserve was established on the area of 240 hectares in 1987 for protection and preservation of rare ecological system of the lake of glacial origin and natural complexes surrounding the water basin.  The lake feeds mainly from rains and spring water.  Lake Ishigli-Gara-Gel is situated at a height of 2, 658 m above sea level in the southern part of the Karabakh volcanic plateau near the foothills of several mountains with a height of 3, 200-3, 500 m. the lake is a relict water reservoir, which was formed in the crater of an extinct volcano.  The length of the lake is 1,950 m, its maximum width is 1, 250 m, length of its coastline is 5, 500 m, maximum depth – 7.8 m, volume of water – 10 million m3, area of the lake 13 km2.  Water flow is mainly due to melted snow and rainwater, partially spring water.  In terms of botany and geography the Karabakh Plateau is situated between the Caucasian and Armenian-Iran provinces, which determines the specifics of the local flora.  The flora of the reserve includes 102 species and subspecies of vascular plants from 68 general and 27 families.  The lack of flora is explained by the fact that the reserve covers only the lake, and many rare and endemic species grow beyond the reserve area, but close to its borders.  The vegetation of the coastal area of the lake is represented mainly by meadows with the dominance of Trifolium and Tragacantha and Astragalus.  The swamp flora and vegetation are limited because of the height of the area.  There are only two species of plants in the lake: Polygonum amphibium and Ranunclus.  In 1967, a type of Sevan trout, included in the Red Book, was introduced into the lake.  The reserve is an inter-republic reserve.  The reserve is under occupation.  Adjacent to the borders of the reserve there are areas with rare and endangered species of plants such as Euphrasia, Potentilla and others. A hierarchical classifier is a classifier that maps input data into defined subsumptive output categories.  The classification occurs first on a low-level with highly specific pieces of input data.  The classifications of the individual pieces of data are then combined systematically and classified on a higher level iteratively until one output is produced.  This final output is the overall classification of the data.  Depending on application-specific details, this output can be one of a set of pre-defined outputs, one of a set of on-line learned outputs, or even a new novel classification that hasn't been seen before.  Generally, such systems rely on relatively simple individual units of the hierarchy that have only one universal function to do the classification.  In a sense, these machines rely on the power of the hierarchical structure itself instead of the computational abilities of the individual components.  This makes them relatively simple, easily expandable, and very powerful. Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae.  The genus comprises about 370 species of trees and shrubs, roughly 300 of which are native to tropical and southern Africa, about 5 to Madagascar, some 25 to tropical Asia and approximately 40 to tropical America.  The genus is absent from Australia.  Though somewhat reminiscent of willows ("Salix") in their habitus, they are not particularly close relatives of these. A voice type is a particular human singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points ("passaggio"), such as breaks and lifts within the voice.  Other considerations are physical characteristics, speech level, scientific testing, and vocal register.  A singer's voice type is identified by a process known as voice classification, by which the human voice is evaluated and thereby designated into a particular voice type.  The discipline of voice classification developed within European classical music and is not generally applicable to other forms of singing.  Voice classification is often used within opera to associate possible roles with potential voices.  Several different voice classification systems are available to identify voice types, including the German "Fach" system and the choral music system among many others; no system is universally applied or accepted. The European Union uses a classification for subnational territory called "Nomenclature des Unites Territriales Statistques" (commonly abbreviated as NUTS).  The NUTS 1 classification is applied to a group of regions, NUTS 2 for regions and NUTS 3 as subdivisions of regions.  There are also two levels (NUTS 4 and 5) which relate to local administrative unit levels.  Countries agree a NUTS classification with the European Commission.  Geddes notes that NUTS level 2 is "particularly important", because they often exist as territorial-government divisions and are used for regional policies by countries.  NUTS 1 typically has a population of 3-7 million; NUTS 2 0.8-3 million; and NUTS 3 150,000-800,000.  As of 2015, there are 98 regions at NUTS 1 level, 276 regions at NUTS 2 level and 1,342 regions at NUTS 3 level "(as a result, statistics at the NUTS level 3 are found as an external link to this article)".  The EU is based on the classification of NUTS 2 regions as: less developed regions, transition regions and more developed regions. In 1984, the International Organization for Succulent Plant Study set up a working party, now called the International Cactaceae Systematics Group, to produce a consensus classification of the cactus family, down to the level of genus.  Their classification has been used as the basis for systems published since the mid-1990s.  Treatments in the 21st century have generally divided the family into around 125–130 genera and 1,400–1,500 species, which are then arranged in a number of tribes and subfamilies.  However, subsequent molecular phylogenetic studies have shown that a very high proportion of the higher taxa (genera, tribes and subfamilies) are not monophyletic, i.e. they do not contain all of the descendants of a common ancestor.  , the internal classification of the family Cactaceae remained uncertain and subject to change.  A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Para-archery classification is the classification system for para-archery used to create a level playing field for archers with a different range of disabilities.  Governance in the sport is through the International Archery Federation.  Early classification systems for the sport were created during the 1940s and based on medical classification.  This has subsequently changed to a functional mobility classification with the exception of blind archery.
