**Violaxanthin Structure and Isomerism Analysis**

The image presents the chemical structure of **violaxanthin**, a type of terpenoid compound. The structure is detailed as a series of connected carbon rings and chains, with multiple double bonds and functional groups, notably hydroxyl (OH) groups. Additionally, there are methyl (CH₃) groups attached at various positions on the carbon chain, contributing to the compound's structural complexity.

**Questions:**

1. **How many double bonds in this terpenoid compound are capable of *cis/trans* isomerism?**
   - [Input box for answer]

2. **Of these, how many are in the *cis* configuration?**
   - [Input box for answer]

**Instructions:**

- Analyze the chemical structure carefully to count the number of double bonds, specifically identifying those that allow for *cis/trans* isomerism. 
- Determine which of these double bonds exist in the *cis* configuration.

**Options:**

- Click on "Submit Answer" to validate your input.
- Alternatively, select "Try Another Version" if you wish to attempt a different version of the question.
