Problem: Due to industrial restructuring and loss of jobs in the auto industry, Detroit lost considerable population from the late 20th century to present. Between 2000 and 2010 the city's population fell by 25 percent, changing its ranking from the nation's 10th-largest city to 18th. In 2010, the city had a population of 713,777, more than a 60 percent drop from a peak population of over 1.8 million at the 1950 census. This resulted from suburbanization, industrial restructuring, and the decline of Detroit's auto industry. Following the shift of population and jobs to its suburbs or other states or nations, the city has focused on becoming the metropolitan region's employment and economic center. Downtown Detroit has held an increased role as an entertainment destination in the 21st century, with the restoration of several historic theatres, several new sports stadiums, and a riverfront revitalization project. More recently, the population of Downtown Detroit, Midtown Detroit, and a handful of other neighborhoods has increased. Many other neighborhoods remain distressed, with extensive abandonment of properties.
What is one of the problems that currently effects property values in Detroit?

Answer: abandonment of properties


Problem: Stems mainly provide support to the leaves and reproductive structures, but can store water in succulent plants such as cacti, food as in potato tubers, or reproduce vegetatively as in the stolons of strawberry plants or in the process of layering. Leaves gather sunlight and carry out photosynthesis. Large, flat, flexible, green leaves are called foliage leaves. Gymnosperms, such as conifers, cycads, Ginkgo, and gnetophytes are seed-producing plants with open seeds. Angiosperms are seed-producing plants that produce flowers and have enclosed seeds. Woody plants, such as azaleas and oaks, undergo a secondary growth phase resulting in two additional types of tissues: wood (secondary xylem) and bark (secondary phloem and cork). All gymnosperms and many angiosperms are woody plants. Some plants reproduce sexually, some asexually, and some via both means.
What are the stems used for in cacti?

Answer: store water


Problem: As Muslim institutions of higher learning, the madrasa had the legal designation of waqf. In central and eastern Islamic lands, the view that the madrasa, as a charitable endowment, will remain under the control of the donor (and their descendent), resulted in a "spurt" of establishment of madaris in the 11th and 12th centuries. However, in Western Islamic lands, where the Maliki views prohibited donors from controlling their endowment, madaris were not as popular. Unlike the corporate designation of Western institutions of higher learning, the waqf designation seemed to have led to the exclusion of non-orthodox religious subjects such a philosophy and natural science from the curricula. The madrasa of al-Qarawīyīn, one of the two surviving madaris that predate the founding of the earliest medieval universities and are thus claimed to be the "first universities" by some authors, has acquired official university status as late as 1947. The other, al-Azhar, did acquire this status in name and essence only in the course of numerous reforms during the 19th and 20th century, notably the one of 1961 which introduced non-religious subjects to its curriculum, such as economics, engineering, medicine, and agriculture. It should also be noted that many medieval universities were run for centuries as Christian cathedral schools or monastic schools prior to their formal establishment as universitas scholarium; evidence of these immediate forerunners of the university dates back to the 6th century AD, thus well preceding the earliest madaris. George Makdisi, who has published most extensively on the topic concludes in his comparison between the two institutions:
