To determine the four contiguous words that share an underlying relationship, we need to look at the given grid and identify a set that is directly connected to one another. Here is the grid for reference:
[tex]\[
\begin{array}{|c|c|c|c|}
\hline \text{Bark} & \text{Scrap} & \text{Debris} & \text{Branch} \\
\hline \text{Boot} & \text{Head} & \text{Crate} & \text{Root} \\
\hline \text{Foot} & \text{Chest} & \text{Suitcase} & \text{Trunk} \\
\hline \text{Squander} & \text{Waste} & \text{Residue} & \text{Hand} \\
\hline
\end{array}
\][/tex]
### Step-by-step Solution:
1. Identify Potential Groups:
- Start by looking at the word "Bark" since it is given in the square mark ([tex]$\square$[/tex] Bark).
- Identify words with a direct connection (either above, below, left, or right but not diagonal).
2. Check Neighboring Words:
- From "Bark", we check the neighboring words: "Scrap" to the right, "Boot" below. None share an obvious relationship.
3. Consider Contextual Relationships:
- Think of the context where "Bark" appears. 'Bark' is part of a tree.
- Considering this, look for other tree-related terms: "Branch", "Root", "Trunk".
4. Check for Adjacency:
- "Branch" is in the same row as "Bark", three columns to the right.
- "Root" is directly below "Branch".
- "Trunk" is directly below "Root".
5. Verify Contiguity:
- Ensure all selected words form a contiguous, connected chain: Above, below, left or right orientations.
The group of words, "Bark", "Branch", "Root", and "Trunk" are all contiguous and form a coherent group related to parts of a tree. Based on this assessment, the coordinates of these words are:
- (0, 0) for "Bark"
- (0, 3) for "Branch"
- (1, 3) for "Root"
- (2, 3) for "Trunk"
Therefore, the four contiguous words that form a coherent group are located at:
[tex]\[\left[(0, 0), (0, 3), (1, 3), (2, 3)\right]\][/tex]
