Problem: The Sumerian language is generally regarded as a language isolate in linguistics because it belongs to no known language family; Akkadian, by contrast, belongs to the Semitic branch of the Afroasiatic languages. There have been many failed attempts to connect Sumerian to other language groups. It is an agglutinative language; in other words, morphemes ("units of meaning") are added together to create words, unlike analytic languages where morphemes are purely added together to create sentences. Some authors have proposed that there may be evidence of a sub-stratum or add-stratum language for geographic features and various crafts and agricultural activities, called variously Proto-Euphratean or Proto Tigrean, but this is disputed by others.
What language has been proven to proceed Sumerian?

Problem: Inner and outer vestibules lead to the octagonal chapter house, which is of exceptional architectural purity. It is built in a Geometrical Gothic style with an octagonal crypt below. A pier of eight shafts carries the vaulted ceiling. To the sides are blind arcading, remains of 14th-century paintings and numerous stone benches above which are innovatory large 4-light quatre-foiled windows. These are virtually contemporary with the Sainte-Chapelle, Paris.
What kind of ceiling is in the chapter house?

Answer: vaulted

Problem: Summers are generally warm and sometimes hot. London's average July high is 24 C (75.2 F). On average London will see 31 days above 25 C (77.0 F) each year, and 4.2 days above 30.0 C (86.0 F) every year. During the 2003 European heat wave there were 14 consecutive days above 30 C (86.0 F) and 2 consecutive days where temperatures reached 38 C (100.4 F), leading to hundreds of heat related deaths. Winters are generally cool and damp with little temperature variation. Snowfall does occur from time to time, and can cause travel disruption when this happens. Spring and autumn are mixed seasons and can be pleasant. As a large city, London has a considerable urban heat island effect, making the centre of London at times 5 C (9 F) warmer than the suburbs and outskirts. The effect of this can be seen below when comparing London Heathrow, 15 miles west of London, with the London Weather Centre, in the city centre.
How far from the center of London is London Heathrow Airport?

Answer:
15 miles west
