Answer:
In 2005, the largest portion of Ukraine's economy was the services sector. According to the World Bank, the services sector accounted for approximately 64% of Ukraine's GDP in 2005. This was followed by industry, which accounted for around 34% of GDP, and agriculture, which accounted for around 2% of GDP.
The services sector in Ukraine includes a wide range of industries, such as finance, real estate, trade, transportation, and hospitality. The growth of the services sector in Ukraine has been driven by factors such as increased consumer spending, rising tourism, and greater foreign investment in the country. However, the sector has also faced challenges such as corruption, lack of investment in infrastructure, and political instability.
