Directions: The 3 - D problem figure shows a view of an object. Identify the correct front view, from amongst the answer figures, looking in the direction of arrow.
Show Hint
Two tall sloping posts with a ramp between them: from the front you see two full-height columns with a horizontal division line, and a lower central part joining them.
The object has two similar blocks, one at the left and one at the right, each about one unit wide and about twice as high at the back as at the front. Each has a vertical front face and a sloping face rising from the top of that front face to the back. Between them a ramp surface rises from the ground to about half the full height at the back. Looking along the arrow (from the front): 1. The left and right blocks both appear as full-height rectangles. On each of them a horizontal line is seen at half height, where the vertical front face ends and the sloping face begins. 2. The ramp between the blocks appears as a rectangle of half the full height, whose top edge is the back edge of the ramp. This top edge lines up with the horizontal lines on the two blocks, so a single horizontal line runs across the whole width at half height. 3. The two vertical lines are the inner edges of the blocks, and the central part is about twice as wide as each column. This is exactly the first answer figure: two full-height columns with a line at half height and a central part only half as high. Answer: (1) the first answer figure
