Answer:
Chang-bo got into trouble with the Ministry for the Protection of State Security because a neighbour reported about him when he blabbered that when boots are being produced in such large quantities then how come his children do not have any.
Step-by-step explanation:
'Nothing to Envy: Ordinary Lives in North Korea' is a novel written by Barbara Demick. The novel is based on the interviews of North Korean refugees, who escaped Noth Korea.
In the book, Chang-bo got into trouble with the Ministry for the Protection of State Security after he was reported by one of his neighbour. When one night Chang-bo alongwith his wife and several neighbours were watching TV, they stopped to watch a business report which was showing how large number of rubber boots were being produced by a shoe factory. After watching the report, Chang-bo wondered that how is it that such large amount of shoes are being produced and his children do not have any of these shoes. His statement got him into trouble with the Ministry as he was then reported by one of his neighbours to the Ministry for the Protection of State Security.
