Passage Excerpt:
In the early 1900s, the construction of the Panama Canal required excavating millions of tons of earth through the Culebra Cut. Landslides were a constant hazard, repeatedly burying equipment and undoing months of progress. [1]
The writer wants to add a sentence at point [1] that emphasizes the immense scale of the excavation effort and the primary technology used to accomplish it. Which choice best fulfills this goal?
- To move the mountain of rock, crews operated over one hundred steam shovels, which filled up to 160 traincars daily with dug-up earth.Cevap
- BMany workers from the Caribbean and Europe traveled to Panama to join the workforce, seeking economic opportunities despite the harsh environment.
- CDue to these geologic hazards, the overall construction of the canal took nearly a decade longer than originally anticipated by American planners.
- DCrews worked day and night to clear the path, they relied on steam-powered machinery to scoop up the heavy rock.
Cevap
To move the mountain of rock, crews operated over one hundred steam shovels, which filled up to 160 traincars daily with dug-up earth.
The correct answer successfully fulfills the rhetorical goal by specifying the technology used (steam shovels) and presenting numbers that illustrate the massive scale of the work (over one hundred steam shovels and 160 traincars daily). It is also grammatically correct.
