Input: Read this: Sicily fell under the control of the Holy Roman Empire in 1194. Palermo was the preferred city of the Emperor Frederick II. Muslims of Palermo emigrated or were expelled during Holy Roman rule. After an interval of Angevin rule (12661282), Sicily came under control of the Aragon and Barcelona dynasties.

QUES: In Austria, the Austrian Constitution of 1920 (based on a draft by Hans Kelsen) introduced judicial review of legislative acts for their constitutionality. This function is performed by the Constitutional Court (Verfassungsgerichtshof), which is also charged with the review of administrative acts on whether they violate constitutionally guaranteed rights. Other than that, administrative acts are reviewed by the Administrative Court (Verwaltungsgerichtshof). The Supreme Court (Oberste Gerichtshof (OGH)), stands at the top of Austria's system of "ordinary courts" (ordentliche Gerichte) as the final instance in issues of private law and criminal law.

QUES: Due to technical limitations, the original ReWritable CD could be written no faster than 4x speed. High Speed ReWritable CD has a different design, which permits writing at speeds ranging from 4x to 12x. Original CD-RW drives can only write to original ReWritable CDs. High Speed CD-RW drives can typically write to both original ReWritable CDs and High Speed ReWritable CDs. Both types of CD-RW discs can be read in most CD drives. Higher speed CD-RW discs, Ultra Speed (16x to 24x write speed) and Ultra Speed+ (32x write speed) are now available.
Why was the original ReWriteable CD written only at speeds faster than 4x?

Question: Czech contains ten basic vowel phonemes, and three more found only in loanwords. They are /a/, //, //, /o/, and /u/, their long counterparts /a/, //, /i/, /o/ and /u/, and three diphthongs, /ou/, /au/ and /u/. The latter two diphthongs and the long /o/ are exclusive to loanwords. Vowels are never reduced to schwa sounds when unstressed. Each word usually has primary stress on its first syllable, except for enclitics (minor, monosyllabic, unstressed syllables). In all words of more than two syllables, every odd-numbered syllable receives secondary stress. Stress is unrelated to vowel length, and the possibility of stressed short vowels and unstressed long vowels can be confusing to students whose native language combines the features (such as English).
Try to answer this question if possible: How many basic vowel phonemes are in English?
Answer: unanswerable

Problem: Lester Brown states that the market "does not incorporate the indirect costs of providing goods or services into prices, it does not value nature's services adequately, and it does not respect the sustainable-yield thresholds of natural systems". It also favors the near term over the long term, thereby showing limited concern for future generations. Tax and subsidy shifting can help overcome these problems, though is also problematic to combine different international normative regimes regulating this issue.
What can help over come the problems with the market?

Tax and subsidy shifting
