In this problem, Barnard is using only a compass to construct the bisector of an angle, but he lacks a straightedge. The key question is whether Barnard can still complete the construction without a straightedge.

### Explanation:
To bisect an angle using only a compass:
1. **Step 1:** Use the compass to draw arcs from each arm of the angle, creating two points of intersection.
2. **Step 2:** Draw additional arcs from these intersection points, finding their intersection somewhere within the angle.

**What’s missing:** To finalize the construction, Barnard would typically use a straightedge to connect the vertex of the angle to the intersection of the arcs, forming the bisector.

Since Barnard does not have a straightedge, he cannot draw the straight line necessary to connect the vertex of the angle to the intersection point of the arcs.

### Correct Answer:
- **"Barnard cannot complete the construction. The remaining step is to connect the vertex of angle A to point B with a straightedge."**
