Problem: Beer is composed mostly of water. Regions have water with different mineral components; as a result, different regions were originally better suited to making certain types of beer, thus giving them a regional character. For example, Dublin has hard water well-suited to making stout, such as Guinness; while the Plzeň Region has soft water well-suited to making Pilsner (pale lager), such as Pilsner Urquell. The waters of Burton in England contain gypsum, which benefits making pale ale to such a degree that brewers of pale ales will add gypsum to the local water in a process known as Burtonisation.
What type of water is best for making pale lager?
The answer is the following: soft water

Problem: Most of Thailand's institutes of technology were developed from technical colleges, in the past could not grant bachelor's degrees; today, however, they are university level institutions, some of which can grant degrees to the doctoral level. Examples are Pathumwan Institute of Technology (developed from Pathumwan Technical School), King Mongkut's Institute of Technology Ladkrabang (Nondhaburi Telecommunications Training Centre), and King Mongkut's Institute of Technology North Bangkok (Thai-German Technical School).
What's the new name of Pathumwan Technical School?
The answer is the following: Pathumwan Institute of Technology

Problem: Population geneticists have debated whether the concept of population can provide a basis for a new conception of race. In order to do this, a working definition of population must be found. Surprisingly, there is no generally accepted concept of population that biologists use. Although the concept of population is central to ecology, evolutionary biology and conservation biology, most definitions of population rely on qualitative descriptions such as "a group of organisms of the same species occupying a particular space at a particular time" Waples and Gaggiotti identify two broad types of definitions for populations; those that fall into an ecological paradigm, and those that fall into an evolutionary paradigm. Examples of such definitions are:
What do Waples and Gaggiotti identify two broad types of?
The answer is the following: definitions for populations

Problem: The Sydney Mandolins (Artistic Director: Adrian Hooper) have contributed greatly to the repertoire through commissioning over 200 works by Australian and International composers. Most of these works have been released on Compact Disks and can regularly be heard on radio stations on the ABC and MBS networks. One of their members, mandolin virtuoso Paul Hooper, has had a number of Concertos written for him by composers such as Eric Gross. He has performed and recorded these works with the Sydney Symphony Orchestra and the Tasmanian Symphony Orchestra. As well, Paul Hooper has had many solo works dedicated to him by Australian composers e.g., Caroline Szeto, Ian Shanahan, Larry Sitsky and Michael Smetanin.
On what media was most of these work released?
The answer is the following:
Compact Disks
