The rainy weather helped construction move quickly.
The hot, humid weather made the work exhausting.
The dry season helped work, while the wet season prevented it.

Answer 1

The best answer is: "The dry season helped work, while the wet season prevented it."

Explanation: Panama’s climate is hot and humid year-round, and heavy rains in the wet season caused flooding, landslides, and mud that repeatedly washed out excavations and slowed or stopped work. The drier months allowed much more progress. The heat and humidity also made work exhausting and increased disease, so those factors mattered too.
