The correct answer is - long lines in stores.
The perestroika is one of those policies in the socialist countries that was very damaging to the economy and general welfare of the countries and their populations. It was a policy with which there was a planned production of goods for the needs of the country, but very often the plans were made in the sense that there will be no problems and obstacles in the production, which very often didn't turned out as such, so there was a lack of lots of products. This meant only limited amount of products for the people and the common picture were very long lines in the stores and people hoping that there will be enough for everyone.
