Draw the structures of the missing reactants, intermediates, or products in the following mechanism, 

**Title: Exploring Reaction Mechanisms: Drawing Missing Structures**

**Objective:**  
To draw the structures of missing reactants, intermediates, or products in the provided reaction mechanism. Focus on including all lone pairs and ignoring stereochemistry and inorganic byproducts.

**Diagram Overview:**  
The mechanism involves a series of transformations starting with an alkene reacting with hydrobromic acid (HBr).

1. **Reactants & Initial Reaction:**  
   The structure features an alkene with a pi bond positioned for reaction with HBr. The lone pairs on bromine and the hydrogen are depicted.

2. **First Formed Intermediate:**  
   Following the initial reaction, an arrow indicates the formation of the first intermediate, which is represented by an empty, dashed box labeled "Draw First Formed Intermediate." 

3. **Rearrangement:**  
   A downward arrow labeled "Rearrangement" leads to another step in the mechanism.

4. **Most Stable Intermediate:**  
   A square labeled "Draw Most Stable Intermediate" indicates this next stage of the reaction mechanism.

5. **Formation of Major Product:**  
   The final step involves the reaction with a bromide ion (Br⁻), leading to the major product formation.

6. **Major Product:**  
   Another dashed box labeled "Draw Major Product" signifies where the final product should be detailed.

**Instructions:**  
- Visualize each step, focusing on electron movement and intermediate stability.
- Include all essential lone pairs.
- Explore how rearrangement stabilizes the intermediates.

**Conclusion:**  
Mastering these mechanisms will enhance your understanding of organic reactions, emphasizing the significance of intermediate structures and rearrangements in determining the reaction pathway and final products.
