Kelly should position the ruler such that the border of the ruler would be against the thing. The parallax error occurs whenever the distance of objects is measured to be less or more than the initial length of this same object.Whenever a viewer watches an element at such an oblique angle corresponding towards the scale, it appeared together in changed or modified location on some kind of scale.

Thus the approach above is right.

Answer from: memester74

To minimize parallax, she should Place the ruler in such a way that the edge is against the object.

Explanation:

When the measurement of the length of an object is lesser or greater than the original length of that object, then the Parallax error happens. The main reason for the occurrence of this type of error is due to the wrong position of eyes to the measurement marking angle. On a scale, an object appears at a different or modified position,When a person views an object at an oblique angle corresponding to the scale. This is where the parallax error comes in existence.

This error can be minimized by placing the device used for measurement on the edge. This will result in making the same level for the device for measurement and the object that is to be measured.
