Answer: You can easily answer this question by looking for keywords in the paragraphs given.
Paragraph one talks about the SAVANNAH AND BRUNSWICK SHIPYARDS since we have the expression "coastal region", which could only refer to shipyards.
Paragraph two presents us the expression "military facilities" which could only refer to MILITARY BASES.
Paragraph three shows us "manufacturing plant", which could only refer to BELL BOMBER PLANT.
