Здравствуйте, помогите, пожалуйста решить задание по английскому языку. Надо отметить высказывание является правдой, ложью, или не указано.
Russia is Taking the Global Step
1. When Russian companies step into a global marketplace, they find many of thesame challenges and issues that international players coming to Russia find. The laws and customs and systems are different. The Russian companies looking to move into markets in Asia and Europe, and in emerging markets, will need to understand a different business culture and legal framework, and ensure they have good advice on how best to work in that marketplace.
2. The attractions of Southeast Asia are the rapidly growing economies of the region. The traditional leading regional economies of Singapore, Malaysia and Thailand, Indonesia, which are setting ambitious infrastructure investment as the cornerstone of its economic growth plans, and Myanmar, which is coming in from decades of economic isolation, are getting increasing attention. The experience of companies moving into the Southeast Asian market has demonstrated a very good understanding of the market. It is known that one of the most important first steps is to get good local advice. Not only legal advice, but general advice to assist in taking political and legal risks.
3. Russian companies moving into Asian markets are often attracted to China primarily for its growth and size. But increasingly they are finding that investment opportunities in Southeast Asia are too good to be ignored and making the move. The future of Russian business will depend not only on Russia attracting international players to its markets, but also on Russian companies making greater inroads internationally. Only a decade ago it was only Russian energy giants, or resources producers, that had moved into the global marketplace. But more and more, they are being joined by infrastructure and construction companies, machinery and equipment manufacturers and Russian mobile telecommunications operators. More Russian corporate players can be expected to follow.
B. Mark the sentences
a) T ( True )
b) F ( False)
c) NG ( Not Given )
