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

Ex Input:
How is a husband referred to?, Context: Knights Grand Cross and Knights Commander prefix Sir, and Dames Grand Cross and Dames Commander prefix Dame, to their forenames.[b] Wives of Knights may prefix Lady to their surnames, but no equivalent privilege exists for husbands of Knights or spouses of Dames. Such forms are not used by peers and princes, except when the names of the former are written out in their fullest forms. Clergy of the Church of England or the Church of Scotland do not use the title Sir or Dame as they do not receive the accolade (i.e., they are not dubbed "knight" with a sword), although they do append the post-nominal letters.

Ex Output:
no equivalent privilege exists for husbands

Ex Input:
How did ITV specifically think bid details had been leaked, Context: In the autumn of 1991, talks were held for the broadcast rights for Premier League for a five-year period, from the 1992 season. ITV were the current rights holders, and fought hard to retain the new rights. ITV had increased its offer from 18m to 34m per year to keep control of the rights. BSkyB joined forces with the BBC to make a counter bid. The BBC was given the highlights of most of the matches, while BSkyB paying 304m for the Premier League rights, would give them a monopoly of all live matches, up to 60 per year from the 1992 season. Murdoch described sport as a "battering ram" for pay-television, providing a strong customer base. A few weeks after the deal, ITV went to the High Court to get an injunction as it believed their bid details had been leaked before the decision was taken. ITV also asked the Office of Fair Trading to investigate since it believed Rupert Murdoch's media empire via its newspapers had influenced the deal. A few days later neither action took effect, ITV believed BSkyB was telephoned and informed of its 262m bid, and Premier League advised BSkyB to increase its counter bid.

Ex Output:
ITV believed BSkyB was telephoned and informed of its 262m bid, and Premier League advised BSkyB to increase its counter bid

Ex Input:
What did the principle of inertia do for general relativity?, Context: The concept of inertia can be further generalized to explain the tendency of objects to continue in many different forms of constant motion, even those that are not strictly constant velocity. The rotational inertia of planet Earth is what fixes the constancy of the length of a day and the length of a year. Albert Einstein extended the principle of inertia further when he explained that reference frames subject to constant acceleration, such as those free-falling toward a gravitating object, were physically equivalent to inertial reference frames. This is why, for example, astronauts experience weightlessness when in free-fall orbit around the Earth, and why Newton's Laws of Motion are more easily discernible in such environments. If an astronaut places an object with mass in mid-air next to himself, it will remain stationary with respect to the astronaut due to its inertia. This is the same thing that would occur if the astronaut and the object were in intergalactic space with no net force of gravity acting on their shared reference frame. This principle of equivalence was one of the foundational underpinnings for the development of the general theory of relativity.

Ex Output:
one of the foundational underpinnings
