Problem: Aspirated consonant:

So-called voiced aspirated consonants are nearly always pronounced instead with breathy voice, a type of phonation or vibration of the vocal folds. The modifier letter ⟨◌ʰ⟩ after a voiced consonant actually represents a breathy-voiced or murmured dental stop, as with the "voiced aspirated" bilabial stop ⟨bʰ⟩ in the Indo-Aryan languages. This consonant is therefore more accurately transcribed as ⟨b̤⟩, with the diacritic for breathy voice, or with the modifier letter ⟨bʱ⟩, a superscript form of the symbol for the voiced glottal fricative ⟨ɦ⟩.

A: a type of phonation or vibration of the vocal folds


Problem: In an effort at revitalizing the city, New Jersey voters in 1976 passed a referendum, approving casino gambling for Atlantic City; this came after a 1974 referendum on legalized gambling failed to pass. Immediately after the legislation passed, the owners of the Chalfonte-Haddon Hall Hotel began converting it into the Resorts International. It was the first legal casino in the eastern United States when it opened on May 26, 1978. Other casinos were soon constructed along the Boardwalk and, later, in the marina district for a total of eleven today. The introduction of gambling did not, however, quickly eliminate many of the urban problems that plagued Atlantic City. Many people have suggested that it only served to exacerbate those problems, as attested to by the stark contrast between tourism intensive areas and the adjacent impoverished working-class neighborhoods. In addition, Atlantic City has been less popular than Las Vegas, as a gambling city in the United States. Donald Trump helped bring big name boxing bouts to the city to attract customers to his casinos. The boxer Mike Tyson had most of his fights in Atlantic City in the 1980s, which helped Atlantic City achieve nationwide attention as a gambling resort. Numerous highrise condominiums were built for use as permanent residences or second homes. By end of the decade it was one of the most popular tourist destinations in the United States.

Question: Apart from residences for upper and middle class households, sanitation is insufficient in most residential areas. Private flush toilets are too expensive for virtually all residents in townships due to their water consumption and installation cost. As a result, access to improved sanitation has not increased much since independence: In Namibia's rural areas 13% of the population had more than basic sanitation, up from 8% in 1990. Many of Namibia's inhabitants have to resort to "flying toilets", plastic bags to defecate which after use are flung into the bush. The use of open areas close to residential land to urinate and defecate is very common and has been identified as a major health hazard.

Problem: Database:

The first task of a database designer is to produce a conceptual data model that reflects the structure of the information to be held in the database. A common approach to this is to develop an entity-relationship model, often with the aid of drawing tools. Another popular approach is the Unified Modeling Language. A successful data model will accurately reflect the possible state of the external world being modeled: for example, if people can have more than one phone number, it will allow this information to be captured. Designing a good conceptual data model requires a good understanding of the application domain; it typically involves asking deep questions about the things of interest to an organisation, like "can a customer also be a supplier?", or "if a product is sold with two different forms of packaging, are those the same product or different products?", or "if a plane flies from New York to Dubai via Frankfurt, is that one flight or two (or maybe even three)?". The answers to these questions establish definitions of the terminology used for entities (customers, products, flights, flight segments) and their relationships and attributes.
