Select the most appropriate option to fill in blank 2.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. diversity.
The passage mentions a variety of industries, professional branches, and specializations, which points to a range of different domains.
Diversity refers to the presence of various different types or elements, which fits the context of a society with a wide range of human activities or interests.
Worry: Doesn’t fit in the context as it refers to concern or anxiety, not variety.
Difficulty: Refers to challenges, which doesn't align with the idea of a range of domains.
Uniformity: Refers to sameness or consistency, which contradicts the idea of variety.
Thus, "diversity" is the most appropriate choice.
