Exacum and Biarum, are which type of items?
plants
Exacum
Exacum is a genus of plant in family Gentianaceae.
 It contains the following species (but this list is incomplete):
Biarum
Biarum is a genus of flowering plants in the Araceae family.
 It is composed of plants that are native to the Middle East, southern Europe (Spain, Portugal, Italy, Balkans), and North Africa.
 "Biarum" are often found growing in rock crevices and graveled soil composed largely of limestone.
Functional item
In the framework of Noam Chomsky's Minimalist Program, items of the lexicon are of two types: with or without substantive content.
 Items of the former category are called lexical items, whereas items of the latter category are functional items.
 Functional items carry the grammatical content of a sentence, which means that by taking them out of the sentence one would still understand the meaning, although it would not be grammatical.
 In other words, they are the 'glue' that holds the sentence together.
 Functional items can also be classified as closed class, that is, belonging to parts of speech that do not easily allow new members.
 If functional items are removed from a sentence, the words that would be left are the lexical items.
 The lexical items of a sentence are those that are used in telegraphic speech; functional items are the grammatical units that hold the sentence together and make it more fluid.
 Functional Items are feature sets.
 Functional items include two type of morphemes.
 Free morphemes, like modals, auxiliaries, determiners, complementizers, and bound morphemes such as nominal and verbal affixes.
 Though functional items have feature structure, the do not enter into θ-marking. Vickrey–Clarke–Groves auction
In auction theory, a Vickrey–Clarke–Groves (VCG) auction is a type of sealed-bid auction of multiple items.
 Bidders submit bids that report their valuations for the items, without knowing the bids of the other people in the auction.
 The auction system assigns the items in a socially optimal manner: it charges each individual the harm they cause to other bidders.
 It also gives bidders an incentive to bid their true valuations, by ensuring that the optimal strategy for each bidder is to bid their true valuations of the items.
 It is a generalization of a Vickrey auction for multiple items. Data item
A data item describes an atomic state of a particular object concerning a specific property at a certain time point.
 A collection of data items for the same object at the same time forms an object instance (or table row).
 Any type of complex information can be broken down to elementary data items (atomic state).
 Data items are identified by object (o), property (p) and time (t), while the value (v) is a function of o, p and t: v = F(o,p,t). Collection (abstract data type)
In computer science, a collection or container is a grouping of some variable number of data items (possibly zero) that have some shared significance to the problem being solved and need to be operated upon together in some controlled fashion.
 Generally, the data items will be of the same type or, in languages supporting inheritance, derived from some common ancestor type.
 A collection is a concept applicable to abstract data types, and does not prescribe a specific implementation as a concrete data structure, though often there is a conventional choice (see Container for type theory discussion). River crossing puzzle
A river crossing puzzle is a type of transport puzzle in which the object is to carry items from one river bank to another, usually in the fewest number of trips.
 The difficulty of the puzzle may arise from restrictions on which or how many items can be transported at the same time, or which or how many items may be safely left together.
 The setting may vary cosmetically, for example, by replacing the river by a bridge.
 The earliest known river-crossing problems occur in the manuscript "Propositiones ad Acuendos Juvenes" (English: Problems to sharpen the young ), traditionally said to be written by Alcuin.
 The earliest copies of this manuscript date from the 9th century; it contains three river-crossing problems, including the fox, goose and bag of beans puzzle and the jealous husbands problem. Combination meal
A combination meal, also referred to as a combo meal, is a type of meal that typically includes food items and a beverage.
 They are a common menu item at fast food restaurants, and other restaurants also purvey them.
 Combination meals may be priced lower compared to ordering items separately, but this is not always the case.
 A combination meal is also a meal in which the consumer orders items à la carte to create their own meal combination.
 The "casada" is a common type of lunch combination meal in Costa Rica and Panama. Flea market
A flea market (or swap meet) is a type of bazaar that rents or provides space to people who want to sell or barter merchandise.
 Used goods, cheap items, collectibles, and antiques are commonly sold.
 Many markets offer fresh produce or baked goods, plants from local farms and vintage clothes.
 Renters of the flea market tables are called vendors.
 It may be indoors, as in a warehouse or school gymnasium; or outdoors, as in a field or parking lot or under a tent.
 Flea markets can be held annually or semiannually, others may be conducted monthly, on weekends, or daily.
 Flea-market vendors may range from a family that is renting a table for the first time to sell a few unwanted household items, to scouts who rove the region buying items for sale from garage sales and other flea markets, and several staff watching the stalls. Clas Ohlson
