QUES: Different linguists therefore take different approaches to the problem of assigning sounds to phonemes. For example, they differ in the extent to which they require allophones to be phonetically similar. There are also differing ideas as to whether this grouping of sounds is purely a tool for linguistic analysis, or reflects an actual process in the way the human brain processes a language.
The phonetical similarity of what thing causes disagreements between phenomes?

ANS: unanswerable

QUES: The most notable difference is that, contrary to other European heraldic systems, the Jews, Muslim Tatars or another minorities would be given the noble title. Also, most families sharing origin would also share a coat-of-arms. They would also share arms with families adopted into the clan (these would often have their arms officially altered upon ennoblement). Sometimes unrelated families would be falsely attributed to the clan on the basis of similarity of arms. Also often noble families claimed inaccurate clan membership. Logically, the number of coats of arms in this system was rather low and did not exceed 200 in late Middle Ages (40,000 in the late 18th century).
Coat of arms would be shared with who else?

ANS: most families sharing origin

QUES: The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE).
What is the name of the solar energy research facility in Japan?

ANS: NEDO

QUES: Present-day Slavic people are classified into West Slavic (chiefly Poles, Czechs and Slovaks), East Slavic (chiefly Russians, Belarusians, and Ukrainians), and South Slavic (chiefly Serbs, Bulgarians, Croats, Bosniaks, Macedonians, Slovenes, and Montenegrins), though sometimes the West Slavs and East Slavs are combined into a single group known as North Slavs. For a more comprehensive list, see the ethnocultural subdivisions. Modern Slavic nations and ethnic groups are considerably diverse both genetically and culturally, and relations between them – even within the individual ethnic groups themselves – are varied, ranging from a sense of connection to mutual feelings of hostility.
West Slavic people consist of which nationalities?

ANS:
Poles, Czechs and Slovaks
