First question in Operator Precedence is confusing

[AMGitName]

Hello. The first question in SQL Deep Dive/Operator precendence/questions.sql is a bit misleading after the update.

* Select people either under 30 or over 50 with an income above 50000
[added later on] Include people that are 50
* that are from either Japan or Australia

There are 3 options to read this after the update for their location filter:

• People under 30 or over/at 50 from either Japan or Australia
• People over/at 50 from either Japan or Australia
• People at exactly 50 from either Japan or Australia

The solution clearly reveals the logic that should be applied (location should apply to the entire range group <30 and >=50).
Please consider question update to avoid confusion for the students.
