Question: The evolution of seed plants and later angiosperms appears to be the result of two distinct rounds of whole genome duplication events. These occurred at 319 million years ago and 192 million years ago. Another possible whole genome duplication event at 160 million years ago perhaps created the ancestral line that led to all modern flowering plants. That event was studied by sequencing the genome of an ancient flowering plant, Amborella trichopoda, and directly addresses Darwin's "abominable mystery."

Answer: How many distinct rounds of genome duplication events are suspected in the evolution of seed plants?

Question: The design and function of department stores in Germany followed the lead of London, Paris and New York. Germany used to have a number of department stores; nowadays only a few of them remain. Next to some smaller, independent department stores these are Karstadt (in 2010 taken over by Nicolas Berggruen, also operating the KaDeWe in Berlin, the Alsterhaus in Hamburg and the Oberpollinger in Munich), GALERIA Kaufhof (part of the Metro AG). Others like Hertie, Wertheim and Horten AG were taken over by others and either fully integrated or later closed.

Answer: What cities influenced how department stores in Germany operated?

Question: The 1971 Local Government White Paper proposed abolishing county boroughs, which would have left Plymouth, a town of 250,000 people, being administered from a council based at the smaller Exeter, on the other side of the county. This led to Plymouth lobbying for the creation of a Tamarside county, to include Plymouth, Torpoint, Saltash, and the rural hinterland. The campaign was not successful, and Plymouth ceased to be a county borough on 1 April 1974 with responsibility for education, social services, highways and libraries transferred to Devon County Council. All powers returned when the city become a unitary authority on 1 April 1998 under recommendations of the Banham Commission.

Answer:
What was the population of Plymouth in 1971?
