For reasons that remain obscure, the planet's thermosphere is at an anomalously high temperature of about 750 K. The planet is too far from the Sun for this heat to be generated by ultraviolet radiation. One candidate for a heating mechanism is atmospheric interaction with ions in the planet's magnetic field. Other candidates are gravity waves from the interior that dissipate in the atmosphere. The thermosphere contains traces of carbon dioxide and water, which may have been deposited from external sources such as meteorites and dust.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where would gravity waves in Neptune's interior appear?
Ah, so.. unanswerable

This age saw the Greeks move towards larger cities and a reduction in the importance of the city-state. These larger cities were parts of the still larger Kingdoms of the Diadochi. Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors. An important factor in maintaining Greek identity was contact with barbarian (non-Greek) peoples, which was deepened in the new cosmopolitan environment of the multi-ethnic Hellenistic kingdoms. This led to a strong desire among Greeks to organize the transmission of the Hellenic paideia to the next generation. Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How did the cites remind themselves of their beginnings ?
Ah, so.. Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors.

Another body established under the Good Friday Agreement, the British–Irish Council, is made up of all of the states and territories of the British Isles. The British–Irish Parliamentary Assembly (Irish: Tionól Pharlaiminteach na Breataine agus na hÉireann) predates the British–Irish Council and was established in 1990. Originally it comprised 25 members of the Oireachtas, the Irish parliament, and 25 members of the parliament of the United Kingdom, with the purpose of building mutual understanding between members of both legislatures. Since then the role and scope of the body has been expanded to include representatives from the Scottish Parliament, the National Assembly for Wales, the Northern Ireland Assembly, the States of Jersey, the States of Guernsey and the High Court of Tynwald (Isle of Man).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many Oireachtas members where there in the original British-Irish Parliamentary Assembly?
Ah, so..
25
