Answer 1

Hey mate here's your answer

The thief was so fast that the policeman could not catch him

Answer 2

We are suggested to end the sentence on- not catch him- in this query.

To get to the answer we need to examine the degree of the sentence and see if relatable change in the degree is possible. If not, we have to change the and then see if the output puts up or not. Else, we have to try conjunctions. Anyways, by inter-changing the subject and object in the statement, as well as maintaining the beforehand meaning, we reach to the final answer which is scripted beneath.

Answer: The thief was so fast that the policeman could not catch him.
