Question: KerPlunk and Ludo, are both which type of items?
Context: 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. 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. Ludo , (from Latin "ludo", "I play") is a strategy board game for two to four players, in which the players race their four tokens from start to finish according to the rolls of a single die.  Like other cross and circle games, Ludo is derived from the Indian game Pachisi, but simpler.  The game and its variations are popular in many countries and under various names. 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). 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. 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. 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). Ludo Troch is a film editor with more than sixty film credits.  His editing credits include "Le Concert", "Séraphine", "Live and Become", "Everybody's Famous! ", "Violette" and "The History of Love".  Troch received the César Award for Best Editing for "Cavale" (2002).  He was also nominated for the Magritte Award for Best Editing three times for his work in "Le Concert", "One Night" and "Not My Type". KerPlunk is a children's game first marketed by the Ideal Toy Company in 1967.  The game consists of a transparent plastic tube, plastic rods called "straws" (normally numbering 26 to 30 in total and of various colours – yellow and red predominantly) and several dozen marbles.  The base contains four separate numbered trays and the straws are passed through holes in the middle of the tube to form a lattice.  The marbles are then placed in the top of the tube and held in place by the lattice.  The onomatopoeic name of the game derives from the sound of the marbles tumbling to the base of the tube during play. German submarine "U-3003" was a Type XXI U-boat (one of the ""Elektroboote"") of Nazi Germany's "Kriegsmarine", built for service in World War II.  She was ordered on 6 November 1943, and was laid down on 27 May 1944 at AG Weser, Bremen as yard number 1162.  She was launched on 18 July 1944, and commissioned under the command of "Kapitänleutnant" Ludo Kregelin, on 22 August 1944.
