Final answer:
Option D.
The main part of Georgia's economy historically included cattle, timber, and trade. Currently, the economy features a significant emphasis on manufacturing, particularly in biotechnology, telecommunications, aviation, and other industries, accounting for a sizable portion of the state's GDP.
Step-by-step explanation:
The main part of Georgia's economy has evolved significantly from its historical origins. Initially envisioned to produce luxury goods, the colony faced challenges with food scarcity and unsuitable soil for certain crops.
Over time, the economy shifted towards cattle, timber, and trade, including the Indian trade via Augusta, which emerged as a major center.
In more recent developments, Georgia has transitioned from a Soviet command economy to a free-market system, with agricultural products and tourism becoming primary activities.
However, manufacturing and industry have grown to account for almost one-third of the gross domestic product (GDP), focusing on sectors like biotechnology, telecommunications, aviation, and shipbuilding.
This industrial growth has resulted in manufacturing providing a significant value-added contribution to the state's economy.
Considering Georgia's economic activities and their historical and current contributions to the GDP, the main part of Georgia's economy today is not solely based on agriculture or tourism but has a significant emphasis on manufacturing.
Please mention the correct option in the final answer: Option D: Manufacturer.
