Problem: Utrecht:

The area surrounding Utrecht Centraal railway station and the station itself were developed following modernist ideas of the 1960s, in a brutalist style. This led to the construction of the shopping mall Hoog Catharijne (nl), music centre Vredenburg (Hertzberger, 1979), and conversion of part of the ancient canal structure into a highway (Catherijnebaan).

The music redeveloped music centre opened in 2014 where the original Vredenburg concert and rock and jazz halls are brought together in a single building.

What opened in the 20th century?

Question: This has led to public discussions if Greece, Portugal, and even Italy would be better off leaving the eurozone to regain economical and financial stability if they would not implement reforms to strengthen their competitiveness as part of the eurozone in time. Greece had the greatest need for reforms but also most problems to implement those, so the Greek exit, also called "Grexit", has been widely discussed. Germany, as a large and financially stable state being in the focus to be asked to guarantee or repay other states debt, has never pushed those exits. Their position is to keep Greece within the eurozone, but not at any cost. If the worst comes to the worst, priority should be given to the euro's stability.
Is there an answer to this question: What is Spain's position on whether or not Greece should be outside the eurozone?

Answer:
unanswerable
