Question Clarity Concern – SAT Practice Problem

I came across a geometry question in your SAT practice materials that involves two intersecting triangles (WQX and YQZ). The solution assumes that the triangles are similar, but the problem does not explicitly state that WX∥YZWX \parallel YZWX∥YZ or provide sufficient information to confirm similarity.

I believe this could be confusing for students, as SAT questions typically do not require unstated assumptions. Could you clarify whether parallelism should have been given or provide an alternative explanation that does not rely on this assumption?

Thank you for your time and for the valuable resources you provide.
