English grammar — embedded question (no inversion and correct tense): Improve the sentence by fixing the underlined part. Original sentence: "We don't know how did the thief made an escape." Choose the best replacement for the highlighted portion.

Given data

• Main clause is declarative: "We don't know …"
• Subclause is an embedded wh-question describing a past event.

Concept/Approach
Embedded questions do not use subject–auxiliary inversion. Use the normal order: "how the thief made (an escape)".

Option analysis

Final Answer
how the thief made
