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

[EX Q]: What would an engine driver have to do to adjust the more modern type of valve?, Context: Steam engines frequently possess two independent mechanisms for ensuring that the pressure in the boiler does not go too high; one may be adjusted by the user, the second is typically designed as an ultimate fail-safe. Such safety valves traditionally used a simple lever to restrain a plug valve in the top of a boiler. One end of the lever carried a weight or spring that restrained the valve against steam pressure. Early valves could be adjusted by engine drivers, leading to many accidents when a driver fastened the valve down to allow greater steam pressure and more power from the engine. The more recent type of safety valve uses an adjustable spring-loaded valve, which is locked such that operators may not tamper with its adjustment unless a seal illegally is broken. This arrangement is considerably safer.[citation needed]
[EX A]: seal illegally is broken

[EX Q]: Which team's coach had nothing to do with the incident ?, Context: On Saturday, July 23, 1989, much of America learned of the AFL for an unintended reason, when the Pittsburgh Gladiators' head coach, Joe Haering, made football history by punching commissioner Jim Foster during a game with the Chicago Bruisers. The national media ran with the story, including a photo in USA Today. The game was played between the two teams in Sacramento's Arco Arena, as part of the AFL's 'Barnstorming America' tour. Foster had walked onto the field of play to mediate an altercation between the two teams when Haering, a former NFL assistant, punched him in the jaw. Haering was suspended without pay.
[EX A]: the Chicago Bruisers

[EX Q]: what is the first amount mentioned?, Context: Despite limited natural resources, intensive development of the agricultural and industrial sectors over the past decades has made Israel largely self-sufficient in food production, apart from grains and beef. Imports to Israel, totaling $77.59 billion in 2012, include raw materials, military equipment, investment goods, rough diamonds, fuels, grain, consumer goods. Leading exports include electronics, software, computerized systems, communications technology, medical equipment, pharmaceuticals, fruits, chemicals, military technology, and cut diamonds; in 2012, Israeli exports reached $64.74 billion.
