In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[Q]: What type of ammunition would not have been common in 1940?, Context: Until the 1950s guns firing ballistic munitions were the standard weapon; guided missiles then became dominant, except at the very shortest ranges. However, the type of shell or warhead and its fuzing and, with missiles the guidance arrangement, were and are varied. Targets are not always easy to destroy; nonetheless, damaged aircraft may be forced to abort their mission and, even if they manage to return and land in friendly territory, may be out of action for days or permanently. Ignoring small arms and smaller machine-guns, ground-based air defence guns have varied in calibre from 20 mm to at least 150 mm.
[A]: guided missiles


[Q]: What was special about Deja Vu?, Context: The feminism and female empowerment themes on Beyoncé's second solo album B'Day were inspired by her role in Dreamgirls and by singer Josephine Baker. Beyoncé paid homage to Baker by performing "Déjà Vu" at the 2006 Fashion Rocks concert wearing Baker's trademark mini-hula skirt embellished with fake bananas. Beyoncé's third solo album I Am... Sasha Fierce was inspired by Jay Z and especially by Etta James, whose "boldness" inspired Beyoncé to explore other musical genres and styles. Her fourth solo album, 4, was inspired by Fela Kuti, 1990s R&B, Earth, Wind & Fire, DeBarge, Lionel Richie, Teena Marie with additional influences by The Jackson 5, New Edition, Adele, Florence and the Machine, and Prince.
[A]: paid homage to Baker


[Q]: Why are reversal ratings important?, Context: For maximum life, capacitors usually need to be able to handle the maximum amount of reversal that a system will experience. An AC circuit will experience 100% voltage reversal, while under-damped DC circuits will experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor. Reversal ratings will often affect the design considerations for the capacitor, from the choice of dielectric materials and voltage ratings to the types of internal connections used.
[A]:
affect the design considerations for the capacitor
