Explanation
A socialist country is a country where the public or the government as a whole is solely responsible for the economy of the country.
A researcher doing a research study on the black market economy meets some sellers that illegally sells goods on the roads. She planned to meet them as their potential buyer and then influenced them to be her subject in her research study that she is doing.
She arranges a secure place to meet her potential subjects and she must be careful because these peoples are dangerous people and might harm her. She must stick to her work and ask the questions related to her study work and not involved in their business.
