Explanation:

1. For "Rice is the chief food for about... world."

The word "chief" here describes the importance of rice as a food. The option "most important, main" matches the meaning of "chief" in this context (the first option refers to a leader, which is not relevant here).

"Pride" in this sentence is the feeling the girl has from her grandmother's praise. "A feeling of deep pleasure or satisfaction" fits, while "tears of sadness" is the opposite of the positive feeling here.

"Public" here means the general community of people. "A community of people as a whole" is correct; the second option describes an amusement park - like place, but "public" refers to people, not the place.

Answer:

most important, main (the second option)

2. For "The little girl smiled with pride when her grandmother... her on the skirt she had made in sewing class."
