The\u00a0object can pass through the opening in any orientation, but it cannot be rotated while it is passing\u00a0through. The external outline of the object is the exact size and shape of the opening without being\u00a0too big or small or having extra protrusions. In the example below, the cube could fit through any\u00a0of the apertures, but the only correct answer is the square projection of the cube that is an exact fit.<br \/>\n<div  class='avia-image-container  av-styling-    avia-builder-el-0  el_before_av_image  avia-builder-el-first  avia-align-center '  itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\"  ><div class='avia-image-container-inner'><div class='avia-image-overlay-wrap'><img class='wp-image-0 avia-img-lazy-loading-not-0 avia_image' src=\"http:\/\/www.kaptest.com\/blog\/prep\/wp-content\/uploads\/sites\/21\/2016\/09\/DAT-Keyhole-A.png\" alt='' title=''   itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><br \/>\nNote that none of the features present within an object, such as overlapping shapes, appear in the\u00a0answer choices; instead, the focus is merely on the outline alone. Because of this, the correct opening\u00a0generally corresponds with one of three projections (reductions of 3D images to flat, 2D images)\u00a0that can be drawn for the object: the top-bottom projection, the front-back projection, or the side\u00a0projection. One way to visualize these projections is to think of what shadow would be created if\u00a0you were to shine a bright light on the object from one direction. Regardless of how you visualize\u00a0the projections, the most efficient way to arrive at the correct answer is to determine the three main\u00a0projections of the object and pick the choice that matches one of these. The following example\u00a0illustrates this technique:<br \/>\n<div  class='avia-image-container  av-styling-    avia-builder-el-1  el_after_av_image  el_before_av_sidebar  avia-align-center '  itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\"  ><div class='avia-image-container-inner'><div class='avia-image-overlay-wrap'><img class='wp-image-0 avia-img-lazy-loading-not-0 avia_image' src=\"http:\/\/www.kaptest.com\/blog\/prep\/wp-content\/uploads\/sites\/21\/2016\/09\/DAT-Keyhole-B.png\" alt='' title=''   itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><br \/>\nThe correct choice is therefore (E). Note how choice (D) is a distractor designed to trap test takers\u00a0who go for the obvious features of the object without paying attention to the finer aspects; this is a\u00a0common perceptual ability trap.<br \/>\nIf you have difficulty visualizing the correct projection, try to imagine what would happen if you\u00a0were to flatten the object against the wall relative to the top\/bottom, front\/back, or left\/right sides.\u00a0Whichever way you crush the original object, the part that remains will represent a correct aperture\u00a0for the problem. A good example of this occurs when crushing a soft drink can. If you crush it from\u00a0top to bottom, you are left with a circular disc. If you crush it from left to right or from front to back,\u00a0though, you are instead left with a rectangular piece. Therefore, if your original object is a circular\u00a0cylinder, the correct projection would be either a rectangle or a circle.<br \/>\nWith practice, focusing on the three main projections will allow you to spend no more than the\u00a0recommended 12.5 minutes on the 15 questions in the Keyholes subsection, which equates to 50\u00a0seconds per question.<br \/>\n<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For each Keyhole question in the PAT of the DAT, you are presented with a 3D object and must determine which of the\u00a0five openings in the answer choices would allow the object to pass through with a perfect fit.
