It's easy to overlook the importance in outlining a process for evaluating each rung in the ladder.
Adding this nuance to the question serves to invite deeper thought and avoid assigning a motivation-based rating (like when you give the Uber driver 5 stars when what you felt was actually just "satisfactory").
A more basic rating question can invite other kinds of influence, such as a motivation in how they'd like their life to be perceived rather than how they genuinely feel it to be.
In surveys with less nuance the data tends to correlate around the extremes.
