Which Asian country opened the Duge Bridge, recognised as the world's highest road bridge at the time of its opening in 2016?

Introduction / Context:
This question relates to world geography and infrastructure, focusing on a record breaking bridge project. The Duge Bridge, also known as Beipanjiang Bridge Duge, gained attention as the world's highest road bridge at the time of its opening, making it a popular current affairs topic.

Given Data / Assumptions:

• The structure is named the Duge Bridge.
• It is described as the world's highest road bridge when opened.
• The options provide four Asian countries: China, Russia, Japan and India.

Concept / Approach:
China has invested heavily in large scale infrastructure, especially record setting bridges across deep valleys and rivers. The Duge Bridge is one of several megaprojects in mountainous regions connecting remote provinces through expressways.

Step-by-Step Solution:
Step 1: Recall that the Duge Bridge spans a deep gorge of the Beipan River in south western China.Step 2: The bridge deck stands hundreds of metres above the river, making it exceptionally high for a road bridge.Step 3: Media reports from around 2016 highlighted China opening the world's highest bridge to traffic, referring to the Duge Bridge.Step 4: Among the options, China is the only country that matches this famous project.Step 5: Therefore, the correct answer is China.

Verification / Alternative check:
One can mentally associate many record setting infrastructure projects, such as high speed rail and long bridges, with China. This includes not only sea bridges but also mountain expressway bridges, reinforcing the link between the Duge Bridge and China.

Why Other Options Are Wrong:
Option B is wrong because Russia, while large, is not associated with the Duge Bridge project.
Option C is wrong because Japan has impressive bridges but not this particular one.
Option D is wrong because India has other major bridges but not the Duge Bridge, which is firmly located in China.

Common Pitfalls:
Candidates may confuse different record holding bridges such as longest sea bridges, tallest pylons or highest rail bridges. Carefully reading that this is a road bridge and recalling news from China about bridges over deep gorges helps anchor the correct answer.

Final Answer:
The Duge Bridge, known as the world's highest road bridge at its opening, is located in China.
