The correct answers are:
B. the location of East Asia near multiple bodies of water makes the region more susceptible to natural hazards;
East Asia is surrounded by multiple bodies of water, where the water is predominantly warm, thus the air masses are warm and wet as well. Because of this, it is very easy for large storms and intensive rainfalls, as well as very strong winds to occur. Also, because of the multiple boundaries of the tectonic plates near the coast, there's lots of earthquakes, which are very damaging by them self, but also create tsunamis that are even more devastating.
D. there will be a decrease in rice consumption;
The biggest consumers in rice, China and India, are countries where the economies are constantly growing, people are getting more money, so the projection is that because of that trend, the consumption of rice will be decreasing. That is because the people will buy food that is more protein rich like the meat, experiment with tasty foods, include foreign cuisine, so there will be less space for the rice.
