Track 4 - Task 3 - Angle Discrimination
Task 3 - Angle Discrimination - You are shown all of the possible lines/angles at the bottom of the display. A single line is shown in the upper section. Your task is to decide which line at the bottom matches the angle of the line at the top. Keep in mind that if the angles are the same the two lines would have one of two possible relationships with each other. One, if the two lines are pointing straight up then, if you extended the length of them they would line up directly on top of each other. And two, for all other lines, the two lines will end up being parallel to each other. That means that if they were extended they would never cross, they would run side by side like railroad tracks.
On level three, one should use the process of elimination as an aid. You will be shown five drawings, each with two lines, that look like the hands on a clock. The center of the middle drawing is missing. The four drawings in the corners are all center pieces. One of them fits the drawing in the middle. By quick comparison of the drawings you can tell that some of the corner drawings could not be the answer, so you can eliminate them as possibilities. By doing this you narrow the choices and increase your chances of getting the answer correct. This is a very good technique to use in many different test situations.
