1. **Problem Statement:** Determine which statement can be used to conclude that quadrilateral XYZW is a parallelogram.
2. **Key Concept:** A quadrilateral is a parallelogram if both pairs of opposite sides are congruent.
3. **Given Statements:**
- XW \cong YZ and XY \cong WZ
- XW \cong YZ and XY \cong WZ (repeated)
- XW \cong YZ and XY \cong YZ
- YN \cong NX and XN \cong NY
4. **Analysis:**
- The first statement says opposite sides XW and YZ are congruent, and opposite sides XY and WZ are congruent. This matches the parallelogram condition.
- The third statement says XY \cong YZ, which are adjacent sides, not opposite.
- The fourth statement involves segments related to diagonals intersecting at N, which does not directly prove parallelogram.
5. **Conclusion:** The correct statement to conclude XYZW is a parallelogram is:
$$\text{XW} \cong \text{YZ} \quad \text{and} \quad \text{XY} \cong \text{WZ}$$
This satisfies the condition that both pairs of opposite sides are congruent, which is a defining property of parallelograms.
