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 is the force of gravity noted as?, Context: Since then, and so far, general relativity has been acknowledged as the theory that best explains gravity. In GR, gravitation is not viewed as a force, but rather, objects moving freely in gravitational fields travel under their own inertia in straight lines through curved space-time – defined as the shortest space-time path between two space-time events. From the perspective of the object, all motion occurs as if there were no gravitation whatsoever. It is only when observing the motion in a global sense that the curvature of space-time can be observed and the force is inferred from the object's curved path. Thus, the straight line path in space-time is seen as a curved line in space, and it is called the ballistic trajectory of the object. For example, a basketball thrown from the ground moves in a parabola, as it is in a uniform gravitational field. Its space-time trajectory (when the extra ct dimension is added) is almost a straight line, slightly curved (with the radius of curvature of the order of few light-years). The time derivative of the changing momentum of the object is what we label as "gravitational force".
[EX A]: The time derivative of the changing momentum of the object

[EX Q]: What and how do some like to view things?, Context: Vowel length is not always considered a distinctive feature in Dutch phonology, because it normally co-occurs with changes in vowel quality. One feature or the other may be considered redundant, and some phonemic analyses prefer to treat it as an opposition of tenseness. However, even if not considered part of the phonemic opposition, the long/tense vowels are still realised as phonetically longer than their short counterparts. The changes in vowel quality are also not always the same in all dialects, and in some there may be little difference at all, with length remaining the primary distinguishing feature. And while it is true that older words always pair vowel length with a change in vowel quality, new loanwords have reintroduced phonemic oppositions of length. Compare zonne(n) [ˈzɔnə] ("suns") versus zone [ˈzɔːnə] ("zone") versus zonen [ˈzoːnə(n)] ("sons"), or kroes [krus] ("mug") versus cruise [kruːs] ("cruise").
[EX A]: One feature or the other may be considered redundant, and some phonemic analyses prefer to treat it as an opposition of tenseness

[EX Q]: Which park in England has an alliterative name?, Context: Another green space in Newcastle is the Town Moor, lying immediately north of the city centre. It is larger than London's famous Hyde Park and Hampstead Heath put together and the freemen of the city have the right to graze cattle on it. The right incidentally extends to the pitch of St. James' Park, Newcastle United Football Club's ground, though this is not exercised, although the Freemen do collect rent for the loss of privilege. Honorary freemen include Bob Geldof, King Harald V of Norway, Bobby Robson, Alan Shearer, the late Nelson Mandela and the Royal Shakespeare Company. The Hoppings funfair, said to be the largest travelling funfair in Europe, is held here annually in June.
