Problem: Please answer a question about the following article about Universal Studios:
During the war years Universal did have a co-production arrangement with producer Walter Wanger and his partner, director Fritz Lang, lending the studio some amount of prestige productions. Universal's core audience base was still found in the neighborhood movie theaters, and the studio continued to please the public with low- to medium-budget films. Basil Rathbone and Nigel Bruce in new Sherlock Holmes mysteries (1942–46), teenage musicals with Gloria Jean, Donald O'Connor, and Peggy Ryan (1942–43), and screen adaptations of radio's Inner Sanctum Mysteries with Lon Chaney, Jr. (1943–45). Alfred Hitchcock was also borrowed for two films from Selznick International Pictures: Saboteur (1942) and Shadow of a Doubt (1943).
In what year was Shadow of a Doubt produced?
A: 1943
Problem: Please answer a question about the following article about United States Army:
The Pentagon bought 25,000 MRAP vehicles since 2007 in 25 variants through rapid acquisition with no long-term plans for the platforms. The Army plans to divest 7,456 vehicles and retain 8,585. Of the total number of vehicles the Army will keep, 5,036 will be put in storage, 1,073 will be used for training, and the remainder will be spread across the active force. The Oshkosh M-ATV will be kept the most at 5,681 vehicles, as it is smaller and lighter than other MRAPs for off-road mobility. The other most retained vehicle will be the Navistar MaxxPro Dash with 2,633 vehicles, plus 301 Maxxpro ambulances. Thousands of other MRAPs like the Cougar, BAE Caiman, and larger MaxxPros will be disposed of.
How many MRAP vehicles has the Pentagon bought since 2007?
A: 25,000
Problem: Please answer a question about the following article about Printed circuit board:
Surface-mount technology emerged in the 1960s, gained momentum in the early 1980s and became widely used by the mid-1990s. Components were mechanically redesigned to have small metal tabs or end caps that could be soldered directly onto the PCB surface, instead of wire leads to pass through holes. Components became much smaller and component placement on both sides of the board became more common than with through-hole mounting, allowing much smaller PCB assemblies with much higher circuit densities. Surface mounting lends itself well to a high degree of automation, reducing labor costs and greatly increasing production rates. Components can be supplied mounted on carrier tapes. Surface mount components can be about one-quarter to one-tenth of the size and weight of through-hole components, and passive components much cheaper; prices of semiconductor surface mount devices (SMDs) are determined more by the chip itself than the package, with little price advantage over larger packages. Some wire-ended components, such as 1N4148 small-signal switch diodes, are actually significantly cheaper than SMD equivalents.
What are SMDs?
A:
surface mount devices
