[Q]: Passage: Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength. Question: What reflector can change the waves polarization?
[A]: ionosphere


[Q]: Passage: The Paymaster General Act 1782 ended the post as a lucrative sinecure. Previously, Paymasters had been able to draw on money from HM Treasury at their discretion. Now they were required to put the money they had requested to withdraw from the Treasury into the Bank of England, from where it was to be withdrawn for specific purposes. The Treasury would receive monthly statements of the Paymaster's balance at the Bank. This act was repealed by Shelburne's administration, but the act that replaced it repeated verbatim almost the whole text of the Burke Act. Question: After 1782, where would money from Paymasters' withdrawal requests go?
[A]:
the Bank of England
