Problem: The New Delhi town plan, like its architecture, was chosen with one single chief consideration: to be a symbol of British power and supremacy. All other decisions were subordinate to this, and it was this framework that dictated the choice and application of symbology and influences from both Hindu and Islamic architecture.
What town plan was chosen with the chief consideration of displaying British power and superiority?
The answer is the following: The New Delhi town plan

Problem: In a famous paper of 1936 with Garrett Birkhoff, the first work ever to introduce quantum logics, von Neumann and Birkhoff first proved that quantum mechanics requires a propositional calculus substantially different from all classical logics and rigorously isolated a new algebraic structure for quantum logics. The concept of creating a propositional calculus for quantum logic was first outlined in a short section in von Neumann's 1932 work, but in 1936, the need for the new propositional calculus was demonstrated through several proofs. For example, photons cannot pass through two successive filters that are polarized perpendicularly (e.g., one horizontally and the other vertically), and therefore, a fortiori, it cannot pass if a third filter polarized diagonally is added to the other two, either before or after them in the succession, but if the third filter is added in between the other two, the photons will, indeed, pass through. This experimental fact is translatable into logic as the non-commutativity of conjunction . It was also demonstrated that the laws of distribution of classical logic, and , are not valid for quantum theory.
What concept was created for quatum logic?
The answer is the following: propositional calculus

Problem: If a state party's withdrawal is successful, its obligations under that treaty are considered terminated, and withdrawal by one party from a bilateral treaty of course terminates the treaty. When a state withdraws from a multi-lateral treaty, that treaty will still otherwise remain in force among the other parties, unless, of course, otherwise should or could be interpreted as agreed upon between the remaining states parties to the treaty.[citation needed]
What happens to a multilateral treaty's rights and obligations among the other parties when just one party withdraws?
The answer is the following: remain in force

Problem: The earthquake had a magnitude of 8.0 Ms and 7.9 Mw. The epicenter was in Wenchuan County, Ngawa Tibetan and Qiang Autonomous Prefecture, 80 km west/northwest of the provincial capital of Chengdu, with its main tremor occurring at 14:28:01.42 China Standard Time (06:28:01.42 UTC), on May 12, 2008 lasting for around 2 minutes, in the quake almost 80% of buildings were destroyed.
What percentage of buildings were destroyed?
The answer is the following:
80%
