Completion of Incomplete Pattern Questions and Answers

Answer: D

The official key is option (D). The given figure is a triangle pointing right whose tip touches a vertical line, with a slanted line rising from the base of a right-angled shape beside it. In option (D) the large triangle on the left has its tip meeting the left side of the small square at the right, and that square contains a vertical side, a base and a slanted line rising from the lower left corner, the same shape as in the given figure and in the same orientation (rotation is not allowed). What was not confirmed in full is that the other three figures lack this part. The key is kept as printed because nothing contradicts it.

Answer: D

The key gives option 4. The figure X is a square split into four cells, in which three cells show the pattern of crossing lines and leaf (lens) shapes and the fourth is hidden. The missing cell has to complete the pattern in the same style as the other cells, so that the lens shapes and the diagonal lines continue across the cell borders. Of the four candidates only the one the key names carries the right line and the right lens, and the other three have lines in the wrong direction or too many lines. This is a figure completion question and the answer follows the official key.

Answer: D

The key gives option 4. The big figure is a grid of black and white squares with the bottom right block hidden. The blocks of the grid repeat as a pattern in which each coloured area continues across the grid, so the missing block must give the right arrangement of black and white squares. Among the four candidates the key names the fourth, which fits the pattern of the neighbouring blocks, while the others place a black or a white square where the pattern needs the opposite. The question is identical in wording to Q11, differing only in the figure.

Answer: C

The original image X, a small lens shape, is embedded in option 3. In an embedded-figure question the given figure must appear unchanged, with the same size and orientation, inside one of the larger figures. The third drawing contains the lens shape in the middle, where its outline is shared by other lines. The first, second and fourth drawings contain curved shapes that look like it but the lens in them is cut by lines, or has a different proportion, so X cannot be traced in them. The answer follows the official key.

Answer: B

Figure 1 contains X. In a question of this type, the given figure must appear unchanged, in the same size and orientation, inside one of the larger figures, with extra lines added around it. The nested squares of figure 1 enclose the same hand-drawn curve as X without altering it, which is why it is the keyed option. The official key names figure 1; figures 2, 3 and 4 are the other three candidates, in which X is not found intact. The way to check is to place X over each candidate and compare detail by detail: X must appear unchanged, not just similar in general shape, and the official key names figure 1 as the candidate where it does.

Answer: B

The S-shaped line X is embedded in option 2. X is a zigzag line with a long upper stroke, a turn and a lower stroke, and it has to be found with its shape unchanged inside the circular drawing. In the second circle, a line running from the top left, turning sharply and ending at the bottom, traces exactly the shape of X. In the other three circles the lines are drawn at different angles, or the turns fall in different places, so the shape cannot be traced. The answer follows the official key.
