Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe taxa that are likely to become endangered in the near future.

2. **Identifying the Options**: The options provided are:
- 1st: Extinct
- 2nd: Rare
- 3rd: Vulnerable
- 4th: Living Fossil

3. **Analyzing Each Option**:
- **Extinct**: This term refers to species that no longer exist. It does not fit the context of species that are still alive but at risk.
- **Rare**: While this term indicates that a species is not commonly found, it does not specifically imply that the species is at risk of becoming endangered.
- **Vulnerable**: This term is used for species that are at risk of becoming endangered unless conservation efforts are made. It implies a higher likelihood of facing extinction in the near future.
- **Living Fossil**: This term refers to species that have remained relatively unchanged over long periods of geological time. It does not indicate a risk of endangerment.

4. **Selecting the Correct Answer**: Based on the definitions and implications of each term, "Vulnerable" is the most appropriate choice as it directly relates to species that are likely to become endangered.

5. **Conclusion**: Therefore, the correct answer is "Vulnerable".
