8. Why was the roadway so dangerous to build?

Answer: D

Explanation:

The roadway was dangerous to build because if it wasn't balanced, it would collapse.

The construction of the roadway was particularly hazardous due to the necessity of maintaining balance to prevent the bridge from collapsing into the bay. This critical aspect of engineering made the task one of the most dangerous parts of the entire build.

A) There weren't enough materials available to build the road.

This option is incorrect as the extract does not mention any shortage of materials during the construction of the roadway. The focus is on the dangers associated with the construction process itself, not on material availability.

B) The workers might get hit by passing cars.

While the extract discusses dangers involved in building the bridge, it does not indicate that workers were at risk of being struck by vehicles. The primary concern highlighted is related to the balance and structural integrity of the bridge rather than vehicular traffic.

C) The men would fall to their deaths.

Although falling is a significant risk associated with high-altitude construction, this option does not capture the specific reason for the roadway's danger as stated in the extract. The focus is on the balance of the structure, which is a more pressing issue than the threat of falling alone.

D) If the road wasn't balanced, it would collapse.

This is the correct answer because the extract explicitly states that maintaining balance was crucial to ensure the bridge wouldn't fall into the bay. This concern about structural integrity underscores the dangers faced by the workers during the construction of the roadway.

Conclusion

The correct answer emphasizes the importance of balance in the construction of the Golden Gate Bridge's roadway, which was vital to prevent collapse. Other options either misinterpret the risks involved or are not supported by the provided context, making them incorrect. Thus, option D is the only choice that accurately reflects the specific dangers faced by the builders.
