Read the given passage carefully and select the best answer to each question out of the five given alternatives.
Despite facing challenges at the domestic level along with a rapidly transforming global landscape, the U.S. economy is still the largest and most important in the world. The U.S. economy represents about 20% of the total global output and is still larger than that of China. Moreover, according to the IMF, the U.S. has the sixth highest per capita GDP (PPP). The U.S. economy features a highly-developed and technologically-advanced services sector, which accounts for about 80% of its output. The U.S. economy is dominated by services-oriented companies in areas such as technology, financial services, healthcare and retail. Large U.S. corporations also play a major role on the global stage, with more than a fifth of companies on the Fortune Global 500 coming from the United States.
Even though the services sector is the main engine of the economy, the U.S. also has an important manufacturing base, which represents roughly 15% of output. The U.S. is the second largest manufacturer in the world and a leader in higher-value industries such as automobiles, aerospace, machinery, telecommunications and chemicals. Meanwhile, agriculture represents less than 2% of output. However, large amounts of arable land, advanced farming technology and generous government subsidies make the U.S. a net exporter of food and the largest agricultural exporting country in the world.
The U.S. economy maintains its powerhouse status through a combination of characteristics. The country has access to abundant natural resources and a sophisticated physical infrastructure. It also has a large, well-educated and productive workforce. Moreover, the physical and human capital is fully leveraged in a free-market and business-oriented environment. The government and the people of the United States both contribute to this unique economic environment. The government provides political stability, a functional legal system, and a regulatory structure that allow the economy to flourish. The general population, including a diversity of immigrants, brings a solid work ethic, as well as a sense of entrepreneurship and risk-taking to the mix. Economic growth in the United States is constantly being driven forward by ongoing innovation, research and development as well as capital investment.
The correct answer is option 4, i.e, 'Wither'.
'Flourish' means 'to grow' or 'to prosper'.
'Oversee' means 'to supervise'.
'Authority' means 'power'.
'Primary' means 'main'.
'Wither' means 'to fade' or 'to perish'.
'Often' means 'frequently'.
The sentence suggests that the government provides political stability, a functional legal system, and a regulatory structure that allow the economy to grow.
The word that carries the most opposite meaning is 'wither', making option 4 as the correct answer.
