Question number 71-73 are based on the following passage.
The study of the analog position of mental representation has many fascinating branches which help illuminate the inner workings of our minds and how we perceive images in our mind's eye. This theory points to the link between the time it takes to solve mental problems and their complexity.
In a now-famous study, Stephen Kosslyn asked subjects to imagine an animal, such as a rabbit, next to either an elephant or a fly. When the image was formed, Kosslyn would ask whether or not the target animal had a particular attribute. For example, Kosslyn might say, -elephant, rabbit, and then - leg. He found that it took subjects longer to answer when the target animal was next to the large animal than when it was next to the small animal. Kosslyn interpreted this to mean that subjects had to zoom in on the image to detect the particular feature. Just as one has difficulty seeing details on small objects, so the subjects could not simply mentally -see details on the smaller object in their mental image.
Second, Kosslyn and colleagues demonstrated that the time it takes to scan between two points depends on the distance between the two points [in a memorized image]. In one experiment, subjects memorized an array of letters separated by different distances. Kosslyn found that the farther apart the letters were from each other, the longer it took to answer questions about one of the letters. One of the principal hypotheses of the analog position of mental representation, which is the idea that mental processing requires one to move sequentially through all intervening steps to solve a problem, is that mental images have regular properties.
In a similar experiment, Kosslyn had subjects memorize pictures of objects like a plane or a motorboat. Then he had them focus on one part of the object (e.g., the motor) and move to another (e.g., the anchor). He found that the time it took to determine whether the second part was present depended on the distance between the two parts in the memorized picture.
Using a completely different paradigm, Shepard and Feng tested the amount of time that it would take for subjects to specify whether two arrows on unfolded blocks matched up. They found a linear relationship between the number of folds between the arrows and the time it took to make this judgment, suggesting that subjects went through a discrete series of organized steps in order to solve this problem.
The final type of experiment showing that mental images have regular properties is perhaps the most famous: mental rotation experiments. In 1971, Shepard and Metzler tested subjects' abilities to make complex figure comparisons. They presented su bjects with a t h ree dimensional - standard figure and a comparison figure which was either identical to the sta ndard figure, or its mirror image; the comparison stimulus was rotated, either clockwise or into third dimension. Shepard and Metzler found that the time needed to judge whether the comparison stimulus was identical or a mirror image depended directly on the size of the angle between the target orientation and the orientation of the standard.

believe that there is no relationship between distance and time
have to keep time with a metronome set up by the experimenter
form a mental picture of the scene and go through all intervening positions in the picture
are tricked by the experimenter into taking a longer time
tend to forget things quickly
