Question

Shown on the left is a pattern printed by repeated use of a single printing block. Which of the printing blocks shown on the right can be used to print the pattern?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is A, D

To determine which printing block(s) can be used to create the pattern shown, let's analyze both the given pattern and the available blocks. Here is the process:

1. The given pattern involves repeated geometric shapes with specific orientations. Carefully observe the arrangement and orientation of each shape.
2. Compare each available printing block with the given pattern to see if it can replicate part or the entire pattern by repeated use: 

• The block in Fig 1 matches a segment of the pattern upon repetition. The orientation and shape of elements align perfectly.

• The block in Fig 4 also matches a segment of the pattern. This block can overlay with Fig 1 to cover the entire pattern successfully.

1. Therefore, by combining repetitions of the blocks in Fig 1 and Fig 4, we can recreate the entire pattern shown on the left.

Thus, the correct blocks to print the pattern are Fig 1 and Fig 4.
