Step 1: Compare first few letters
All words begin with “Pre” except "Praise" which begins with "Pra".
In dictionary order, "Pra" comes before "Pre".
So the first word is Praise (b).
Step 2: Arrange remaining “Pre...” words
We now arrange: Preach (a), Precinct (c), Precept (d).
Compare letter by letter:
- Prea... (Preach) comes before Prec... (Precinct, Precept).
Step 3: Order Precinct and Precept
Between “Precept” and “Precinct”: “Prece” (Precept) comes before “Preci” (Precinct) in the dictionary.
Step 4: Final sequence
2 (Praise), 1 (Preach), 4 (Precept), 3 (Precinct).
\[
\boxed{2, 1, 4, 3}
