Final answer:
The statement, "the bridge ahead allow room only for two lanes of traffic," is true (1) because the bridge ahead only accommodates two lanes of traffic.
Step-by-step explanation:
Bridges are engineered with specific lane capacities to ensure structural integrity and safety. In the case of a bridge allowing room for only two lanes of traffic, it means the width and load-bearing capacity are designed for two lanes, restricting additional lanes for safety reasons. Engineering considerations account for factors like weight distribution, the span of the bridge, and the materials used. Increasing the lanes might compromise the bridge's strength, potentially leading to structural issues or accidents due to overcrowding. Therefore, adhering to the designated lane capacity is crucial for maintaining the bridge's stability and ensuring the safety of commuters.
The restriction of two lanes on the bridge emphasizes the need for compliance with its designed capacity, preventing potential hazards that could arise from exceeding its limitations.
Correct answer is: 1) True
