Problem: Spain is a unitary state with a high level of decentralisation, often regarded as a federal system in all but name or a "federation without federalism". The country has been quoted as being "an extraordinarily decentralized country", with the central government accounting for just 18% of public spending, 38% for the regional governments, 13% for the local councils, and the remaining 31% for the social security system. The current Spanish constitution has been implemented in such a way that, in many respects, Spain can be compared to countries which are undeniably federal.

Problem: The third-generation iPod had a weak bass response, as shown in audio tests. The combination of the undersized DC-blocking capacitors and the typical low-impedance of most consumer headphones form a high-pass filter, which attenuates the low-frequency bass output. Similar capacitors were used in the fourth-generation iPods. The problem is reduced when using high-impedance headphones and is completely masked when driving high-impedance (line level) loads, such as an external headphone amplifier. The first-generation iPod Shuffle uses a dual-transistor output stage, rather than a single capacitor-coupled output, and does not exhibit reduced bass response for any load.
What kind of headphones could partially mitigate the bass response issues of the 3rd gen iPods?

Answer: high-impedance

Problem: A culinary staple of North Carolina is pork barbecue. There are strong regional differences and rivalries over the sauces and methods used in making the barbecue. The common trend across Western North Carolina is the use of premium grade Boston butt. Western North Carolina pork barbecue uses a tomato-based sauce, and only the pork shoulder (dark meat) is used. Western North Carolina barbecue is commonly referred to as Lexington barbecue after the Piedmont Triad town of Lexington, home of the Lexington Barbecue Festival, which attracts over 100,000 visitors each October. Eastern North Carolina pork barbecue uses a vinegar-and-red-pepper-based sauce and the "whole hog" is cooked, thus integrating both white and dark meat.
What is another name for Western North Carolina Barbecue?
