According to traditional general knowledge compilations, in which continent is the longest railway bridge of the world said to be located?

Introduction / Context:
This question reflects older style general knowledge about longest and largest structures. In many classic GK books, the longest railway bridge of the world is linked with a structure over the Lower Zambezi River, and the question is simplified by asking only for the continent where this bridge is located. Rather than focusing on up to date engineering records, the item expects aspirants to match the answer key used in those question banks, which identify Africa as the continent where the longest railway bridge, as described in that material, is found.

Given Data / Assumptions:

• The question stems from traditional GK, not necessarily from the latest construction statistics.
• Options are America, Africa, Europe and Malaysia (a country but used in exam options for region).
• We assume the reference is to an older record associated with the Lower Zambezi area.
• The expected exam answer is the continent where that bridge is situated.

Concept / Approach:
For this type of traditional question, the method is to recall the association used in practice sets rather than recomputing modern rankings. Several GK sources mention the Lower Zambezi railway bridge and state that the longest railway bridge is located in Africa. Although modern data might list different bridges and countries, exam questions that copy this older wording generally keep the same answer. Therefore, when presented with these four options, the safe and expected choice in competitive exams following that style is Africa as the location of the longest railway bridge.

Step-by-Step Solution:
Step 1: Recognise that this is a classical GK question which often appears unchanged across many practice books. Step 2: Recall that such books frequently mention a railway bridge over the Zambezi River in Africa as the example of longest railway bridge. Step 3: Map this information to the continental level and note that Zambezi flows in southern Africa. Step 4: Look at the options and identify Africa as the continent matching this reference. Step 5: Choose Africa as the correct answer in line with the conventional exam key.

Verification / Alternative check:
As a check, remember that newer world records for bridges are often associated with Asian countries such as China, but those bridges are not the subject of this specific old style question. Instead, exam books compiled many years ago most often mention Africa when they discuss the longest railway bridge. If a learner has practised similar questions in standard GK sets, they will have seen Africa given as the answer repeatedly, which supports selecting Africa here despite possible changes in actual record holders over time.

Why Other Options Are Wrong:
America does have many long bridges, but in this particular traditional GK item the bridge under discussion is not located in North or South America. Europe contains famous rail and road bridges, yet older exam books do not associate it with the longest railway bridge for this question. Malaysia is a country in Asia, not a continent, and including it as an option is mainly to test whether candidates recall that the expected answer is Africa rather than a specific Asian country.

Common Pitfalls:
One common error is to think of current engineering news, where new records are often in China, and then try to map those to the options, which can cause confusion. Another pitfall is to over analyse the wording and become distracted by the presence of Malaysia in the list. To avoid losing marks, aspirants should recognise that some general knowledge questions in exams are still based on older data and are best answered by recalling the standard key from trusted practice sources, which in this case clearly points to Africa.

Final Answer:
According to traditional general knowledge sources used in many exams, the longest railway bridge is located in Africa.
