Explanation:

1. First option analysis: The Green Revolution increased agricultural productivity in Asia, so countries that were food importers (due to low production) could become self - sufficient or even exporters, so the first statement is correct.
2. Second option analysis: With the Green Revolution, agricultural productivity increased due to better seeds, fertilizers, etc. This led to more efficient farming, and as a result, a smaller percentage of the population is needed to work in agriculture (since more food can be produced with less labor), so this statement is correct.
3. Third option analysis: The Green Revolution promoted the use of modern agricultural techniques and inputs. This led to the growth of large - scale industrial farms (using mechanization, chemical fertilizers, pesticides, etc.) which often replaced small - scale traditional or organic farms, so this statement is correct.

Since all three statements are correct, the last option "all answers are correct" is the right choice.

Answer:

The correct option is the one with the text "all answers are correct". (Assuming the last option's box is to be checked, and if we consider the options as presented, the answer is the option stating "all answers are correct".)
