## Flowchart: Cognitive Process for Solving Percentage Problems
### Overview
The image depicts a flowchart illustrating the cognitive and neural processes involved in solving the percentage problem: "What percent is 120 of 90?" It breaks the solution into four stages: **Knowledge Recall**, **Semantic Understanding**, **Math**, and **Decision Making**. Each stage includes a brain diagram highlighting specific regions (frontal, parietal, temporal lobes, hippocampus) and explanatory text. A flowchart at the bottom visualizes the progression between stages using color-coded arrows.

### Components/Axes
1. **Stages**:
- **Knowledge Recall**: Formula for percentage calculation.
- **Semantic Understanding**: Identifying "part" (120) and "whole" (90).
- **Math**: Calculation of `120 / 90 * 100%`.
- **Decision Making**: Matching the result to the correct option.
2. **Brain Regions**:
- **Frontal Lobe** (green): Highlighted in Knowledge Recall and Decision Making.
- **Temporal Lobe** (orange): Highlighted in Semantic Understanding.
- **Parietal Lobe** (yellow): Highlighted in Math.
- **Hippocampus** (gray): Present in all brain diagrams.
3. **Flowchart Arrows**:
- Green (frontal lobe) → Orange (temporal lobe) → Yellow (parietal lobe) → Green (frontal lobe).

- **Brain Diagram**: Temporal lobe highlighted.
- **Hippocampus**: Labeled in the diagram.
#### Math
- **Text**: "Calculate 120 / 90 * 100% = 133 1/3%."
- **Brain Diagram**: Parietal lobe highlighted.
- **Hippocampus**: Labeled in the diagram.
#### Decision Making
- **Text**: "Option (A) corresponds to 133 1/3%."
- **Brain Diagram**: Frontal lobe highlighted.
- **Hippocampus**: Labeled in the diagram.
#### Flowchart
- **Arrows**:
- Green (frontal lobe) → Orange (temporal lobe): Knowledge Recall → Semantic Understanding.
- Orange (temporal lobe) → Yellow (parietal lobe): Semantic Understanding → Math.
- Yellow (parietal lobe) → Green (frontal lobe): Math → Decision Making.

### Key Observations
1. **Correct Answer**: Option (A) 133 1/3% is selected in the Decision Making stage.
2. **Cognitive Flow**: The problem-solving process progresses sequentially from recalling the formula to applying it and making a decision.
3. **Brain Region Roles**:
- Frontal lobe: Involved in formula recall and final decision.
- Temporal lobe: Processes semantic understanding of "part" and "whole."
- Parietal lobe: Handles mathematical computation.
- Hippocampus: Consistently present, suggesting memory integration across stages.

### Interpretation
The flowchart demonstrates how solving a percentage problem engages distributed neural networks:
- **Frontal Lobe**: Critical for both retrieving prior knowledge (formula) and making final decisions.
- **Temporal Lobe**: Specializes in contextual understanding of numerical relationships.
- **Parietal Lobe**: Dedicated to arithmetic operations.
- **Hippocampus**: Acts as a hub for integrating memory across stages.
The color-coded arrows in the flowchart reinforce the hypothesis that problem-solving is a modular process, with distinct brain regions handling specific cognitive tasks. The correct answer (A) emerges from this coordinated neural activity, emphasizing the interplay between memory, comprehension, computation, and decision-making.
