In this experiment, there are eight pairs of photographs, giving eight points along the orbit of Mars. If you were given more pairs of photographs would the result be better or worse

With the increase in the number of pairs, there will be more points thus these will lead to better result.

Explanation:

As the number of pairs of photographs have increased there are more points to work with. as the number of points is more, the interpolation for estimation of the orbit is better and thus the result is better for more pair of photographs.
