Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the alternative name of the "copper wire test."

2. **Identifying the Test**: The copper wire test is specifically used for detecting halides in a sample.

3. **Naming the Test**: The copper wire test is also known as "Bilstein's test."

4. **Explanation of the Test**:
- In this test, a copper wire (often coated with copper(II) oxide) is heated in the presence of a halide.
- When the copper wire comes into contact with halides, it reacts to form copper halide.
- This reaction produces a characteristic green flame, which indicates the presence of halides.

5. **Conclusion**: Therefore, the copper wire test is called Bilstein's test.
