A. This fact was established in the 1730s by French survey expenditions to Equador near the Equator and Lapland in the Arctic, which found that around the middle of the earth the arc was about a kilometer shorter.
B. One of the unsettled scientific questions in the late 18th century was that exact nature of the shape of the earth.
C. The length of one-degree arc would be less near the equatorial latitudes than at the poles.
D. One way of doing that is to determine the length of the arc along a chosen longitude or meridian at one degree latitude separation.
E. While it was generally known that the earth was not a sphere but an ‘oblate spheroid’, more curved at the equator and flatter at the poles, the question of ‘how much more’ was yet to be established.
Statement B is the first sentence of the paragraph. It introduces the topic. This is followed by E, which dwells more on the 'unsettled scientific questions' talked about in B. Also there is link between statements E and D as D provides the solution to the question asked in E. This is followed by sentence C and A is the closing sentence of the paragraph.
