4. what is the current condition of the towns of pripyat and chernobyl?

Brief Explanations:

Pripyat and Chernobyl were severely affected by the 1986 Chernobyl nuclear disaster. Pripyat is a ghost - town with abandoned buildings, overgrown vegetation, and still has high levels of radiation in some areas. Chernobyl also has abandoned structures, but there is a small population living in the area, mainly those involved in radiation monitoring and de - contamination efforts. The Exclusion Zone around them remains restricted, but has also become a site of scientific study and some tourism.

Answer:

Pripyat is a largely abandoned ghost - town with overgrown vegetation and residual radiation. Chernobyl has some abandoned structures, a small population involved in radiation - related work, and is part of a restricted Exclusion Zone that also sees scientific study and some tourism.
