Frequently I'm confused by the comparison SC s.
Here we like to compare the surface velocity of the equator to that of other latitude.
Now I failed to understand how A compares perfectly?
Aided by the boost it received from being launched near the equator, where the surface velocity of the earth is greater than at other latitudes, the French rocket Ariane carried a communications satellite nearly 25,000 miles into space.
(A) where the surface velocity of the earth is greater than
at other latitudes
(B) where the surface velocity is greater for the earth than other latitudes are
(C) where the earth’s surface has a greater velocity than other latitudes have
(D) with the earth’s surface velocity greater there than
at other latitudes
(E) the surface velocity of earth being greater there than other latitudes
We are left with A and E as we need 'at' for comparison to be correct ..... comaparing 'at equator' and 'at other latitudes'
other options compare the surface velocity of the equator to that of other latitude
Now out of A and E ---- equator is a place. Hence, 'where' is correct and in addition to that i feel 'the surface velocity of the earth' is better than 'earth’s surface velocity'.
