text_A: During the last three decades, the Dominican economy, formerly dependent on the export of agricultural commodities (mainly sugar, cocoa and coffee), has transitioned to a diversified mix of services, manufacturing, agriculture, mining, and trade. The service sector makes up the majority of total GDP, at 60%, with manufacturing making up another 22%; within the service sector, the sub-sectors of tourism, telecommunications, and finance are the primary components, but none alone makes up more than 10% of the sector. The Dominican Republic has a stock market, Bolsa de Valores de la Republica Dominicana (BVRD). and advanced telecommunication system and transportation infrastructure. High unemployment and income inequality are long-term challenges. International migration affects the Dominican Republic greatly, as it receives and sends large flows of migrants. Mass illegal Haitian immigration and the integration of Dominicans of Haitian descent are major issues. A large Dominican diaspora exists, mostly in the United States, contributes to development, sending billions of dollars to Dominican families in remittances.
text_B: Although the passage seems to be implying that tourism takes up X% of the total GDP that is captured by the service sector, and not X% of the total nation's GDP, if we assume that actually the latter is being implied by the passage, could we calculate that tourism, telecom and finance together could account for more than one third of the entire economy?
NO.
