It threatened the collapse of large financial institutions, which was prevented by the bailout of banks by national governments, but stock markets still dropped worldwide. In many areas, the housing market also suffered, resulting in evictions, foreclosures and prolonged unemployment. The crisis played a significant role in the failure of key businesses, declines in consumer wealth estimated in trillions of U.S. dollars, and a downturn in economic activity leading to the 2008–2012 global recession and contributing to the European sovereign-debt crisis. The active phase of the crisis, which manifested as a liquidity crisis, can be dated from August 9, 2007, when BNP Paribas terminated withdrawals from three hedge funds citing "a complete evaporation of liquidity".
What action in 2007 by national governments prevented the collapse of large financial institutions?
bailout of banks

Fortaleza del Cerro overlooks the bay of Montevideo. An observation post at this location was first built by the Spanish in the late 18th century. In 1802, a beacon replaced the observation post; construction of the fortress began in 1809 and was completed in 1839. It has been involved in many historical developments and has been repeatedly taken over by various sides. In 1907, the old beacon was replaced with a stronger electric one. It has been a National Monument since 1931 and has housed a military museum since 1916. Today it is one of the tourist attractions of Montevideo.
What replaced the observation post in 1802?
a beacon

In flood lamps used for photographic lighting, the tradeoff is made in the other direction. Compared to general-service bulbs, for the same power, these bulbs produce far more light, and (more importantly) light at a higher color temperature, at the expense of greatly reduced life (which may be as short as two hours for a type P1 lamp). The upper temperature limit for the filament is the melting point of the metal. Tungsten is the metal with the highest melting point, 3,695 K (6,191 °F). A 50-hour-life projection bulb, for instance, is designed to operate only 50 °C (122 °F) below that melting point. Such a lamp may achieve up to 22 lumens per watt, compared with 17.5 for a 750-hour general service lamp.
How does the color temperature differ for photographic lighting?
higher color temperature
