To answer the question:
When Aleph constructs \( \overline{ZR} \), a line segment bisector of \( \overline{XY} \), it means that point Z is the midpoint of segment \( XY \). This implies that point Z divides the segment \( XY \) into two equal parts.
Given that \( XY = 22 \) units, the length of each half, which is also \( ZY \), would be:
\[ ZY = \frac{XY}{2} = \frac{22}{2} = 11 \text{ units} \]
Thus, the correct responses are:
- Point Z is the midpoint of \( \overline{XY} \).
- \( ZY = 11 \text{ units} \).
Put together, the final response would be: "Point Z is the midpoint of \( \overline{XY} \). ZY = 11 units."
