Concept:The sentence must be rearranged by swapping wrongly placed words to make it grammatically correct and meaningful.
Explanation:The original sentence is:
"The indigenous (A) of the new policy was bolster (B) to protect implementation (C) industries and intended (D) the national economy."
Here, "indigenous" does not fit at the beginning, and "bolster" does not fit after "was".
The correct sentence should start with "implementation" and use "intended" after "was".
So, interchange A with C: "indigenous" and "implementation" swap places.
Also, interchange B with D: "bolster" and "intended" swap places.
After doing both swaps, the sentence becomes:
"The implementation of the new policy was intended to protect indigenous industries and bolster the national economy."
This is grammatically correct and meaningful.
Answer:Option A — A-C and B-D
