Zorluk: OrtaSelecting Concluding Sentences and Transitions

Paragraph 1

Completed in 2012, the Tokyo Skytree stands as one of the tallest structures in the world, rising 634 meters above a city prone to frequent earthquakes. To prevent the tower from collapsing during seismic activity, engineers turned to traditional Japanese architecture for inspiration. Specifically, they analyzed the design of ancient five-story pagodas, which have withstood centuries of tremors. Pagodas feature a central pillar, known as a *shinbashira*, that is structurally independent of the surrounding stories. During an earthquake, the pillar and the outer frame sway out of phase with one another, effectively canceling out much of the seismic energy.

Paragraph 2

The Skytree incorporates a modern version of this system: a massive central concrete column that is connected to the outer steel truss only by fluid dampers. When seismic waves strike, the outer frame sways while the central column resists the motion, absorbing the energy through the dampers. Under extreme conditions, this system can reduce the overall movement of the tower by up to 50 percent. ___________

The writer wants to conclude the passage by emphasizing how the combination of ancient design and modern technology ensures the safety of the Skytree. Which choice best accomplishes this goal?

  1. A
    Traditional pagodas are architectural marvels, the Skytree successfully replicates their stability through the use of modern fluid dampers.
  2. B
    Modern engineers studied these ancient structures, and they will use this knowledge to ensure the Skytree survived future earthquakes.
  3. By adapting the timeless mechanics of the pagoda's central pillar to contemporary construction, this design ensures that the Skytree remains safe during major earthquakes.Cevap
  4. D
    The safety systems, that merge historical pagoda architecture with modern dampers, protect the Skytree from severe seismic damage.

Cevap

The option that begins with 'By adapting the timeless mechanics...' is the correct choice because it logically connects ancient pagoda principles with contemporary engineering to explain how the Skytree is kept safe.
The correct option successfully fulfills the writer's goal of demonstrating how ancient design (the pagoda's central pillar) combined with modern technology (contemporary construction) ensures the Skytree's safety (remains safe during major earthquakes). It is also grammatically correct.

Adım Adım Çözüm

1
Analyze the prompt's rhetorical goal.
The final sentence must emphasize the combination of ancient design, modern technology, and the resulting safety of the Skytree.
Understanding the specific parameters of the concluding sentence helps eliminate choices that introduce irrelevant details or omit necessary components.
2
Evaluate the grammar of each option.
Three options contain grammatical errors: a comma splice, an illogical tense shift, and misplaced commas around a restrictive relative clause.
ACT English questions require sentences to be both rhetorically effective and grammatically correct.
3
Compare the remaining grammatically correct option against the rhetorical goal.
The sentence combining the 'timeless mechanics of the pagoda' with 'contemporary construction' to ensure the Skytree 'remains safe' satisfies all criteria.
This confirms the correct option logically wraps up the passage's themes while maintaining grammatical precision.
