Correct answer: A. Transparency and accountability
Explanation: The direct answer is A: transparency and accountability weaken. An elected government receives authority from voters, but election alone does not excuse it from explaining its actions. The reasoning is: people elect leaders; leaders make policies and use public authority; citizens need reliable information to examine those actions; if information is hidden, citizens cannot properly question performance or demand reasons. Therefore openness, or transparency, and responsibility to the public, or accountability, are both damaged. Option A is correct because these two democratic values are directly connected. Option B, hereditary right, belongs to succession by family and is not the issue here. Option C, state ceremony, refers to formal public events and does not show whether government work is open or answerable. Option D, linguistic diversity, means the presence of different languages; it is valuable but hiding information does not directly weaken it. Exam cue: elected government plus hidden information usually points to weak transparency and accountability.
