Sure, I can help you check your answers!

For question 3, the correct answer is A. household responsibility system.

To arrive at this answer, you can eliminate options C and D since they are not related to the context of agriculture in China during the 1980s. Option B, community, is also incorrect because the commune-based system was actually replaced by a system that shifted responsibilities from the community to individual households. This leaves us with the correct answer, A. household responsibility system.

For question 4, the correct answer is B. Vietnam's current level of rice exports challenges that of India.

To determine the correct answer, you can analyze each option. Option A, Vietnam is no longer a communist country, is incorrect as Vietnam is still considered a communist country. Option C, Hanoi is the main center of Vietnam's marketplace economy, is also incorrect because Ho Chi Minh City (formerly Saigon) is the main center of Vietnam's marketplace economy. Option D, Vietnamese farmers have long specialized in the production of Arabica coffee, is incorrect as Vietnam is actually one of the world's largest producers of Robusta coffee.

This leaves us with the correct answer, B. Vietnam's current level of rice exports challenges that of India, which is a true statement.

I hope this helps! Let me know if you have any other questions.
