Short Answer 
To determine if Block 3 matches the original block O, first identify the three distinct shapes (circle, shape with three connected dots, shape with two connected dots) on Block O. Then, analyze Block 3, noting that it contains the same shapes but in a different orientation, and finally compare it with other blocks to confirm that Block 3 is the only one that replicates the original’s characteristics accurately.
Step 1: Identify the Shapes
Begin by carefully examining the original block O. It displays three distinct shapes on its sides:
- Circle
- Shape with three connected dots
- Shape with two connected dots
These shapes will be essential for comparison with the other blocks.
Step 2: Analyze Block 3 Orientation
Next, look closely at Block 3. It features the same three shapes as the original block O, but they are presented in a different orientation. Confirm that the arrangement includes:
- Circle
- Shape with three connected dots
- Shape with two connected dots
This step involves rotating the block in your mind to visualize how the shapes align with those in the original block.
Step 3: Compare with Other Blocks
Finally, compare Block 3 with the other blocks. Check if any of the other blocks match the original block O in terms of both shape presence and orientation. It’s important to note that:
- No other blocks should have the same shapes as the original.
- No other blocks should display the same arrangement or orientation.
Conclude that Block 3 is the only one that successfully replicates the characteristics of the original block O.
