TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: What is sometimes combined with an RPG tube to keep from harming the user?, Context: Rocket-propelled grenades can be—and often are—used against hovering helicopters (e.g., by Somali militiamen during the Battle of Mogadishu (1993)). Firing an RPG at steep angles poses a danger to the user, because the backblast from firing reflects off the ground. In Somalia, militia members sometimes welded a steel plate in the exhaust end of an RPG's tube to deflect pressure away from the shooter when shooting up at US helicopters. RPGs are used in this role only when more effective weapons are not available.

SOLUTION: a steel plate in the exhaust end

PROBLEM: What are lifts?, Context: Stage lifts and orchestra lifts are specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage. For example, Radio City Music Hall has four such elevators: an orchestra lift that covers a large area of the stage, and three smaller lifts near the rear of the stage. In this case, the orchestra lift is powerful enough to raise an entire orchestra, or an entire cast of performers (including live elephants) up to stage level from below. There's a barrel on the background of the image of the left which can be used as a scale to represent the size of the mechanism

SOLUTION: specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage

PROBLEM: who is the last lady mentioned?, Context: In July 2002, Beyoncé continued her acting career playing Foxxy Cleopatra alongside Mike Myers in the comedy film, Austin Powers in Goldmember, which spent its first weekend atop the US box office and grossed $73 million. Beyoncé released "Work It Out" as the lead single from its soundtrack album which entered the top ten in the UK, Norway, and Belgium. In 2003, Beyoncé starred opposite Cuba Gooding, Jr., in the musical comedy The Fighting Temptations as Lilly, a single mother whom Gooding's character falls in love with. The film received mixed reviews from critics but grossed $30 million in the U.S. Beyoncé released "Fighting Temptation" as the lead single from the film's soundtrack album, with Missy Elliott, MC Lyte, and Free which was also used to promote the film. Another of Beyoncé's contributions to the soundtrack, "Summertime", fared better on the US charts.
