Zorluk: KolayExplicit Main Idea

Run-flat tire inserts are critical safety components that allow tactical wheeled vehicles to maintain mobility after suffering severe tire damage. When a conventional pneumatic tire is punctured by ballistics or road hazards, it rapidly deflates and collapses, leaving the wheel rim unprotected and immobilizing the vehicle. In contrast, run-flat systems feature a rigid internal ring mounted directly onto the wheel rim inside the tire. Even if total air pressure is lost, this reinforced composite ring supports the vehicle's weight and enables the crew to drive safely out of hostile danger zones.

Which of the following statements best expresses the main idea of the passage?

  1. Run-flat tire inserts enable tactical vehicles to keep moving even after sustaining severe tire damage.Cevap
  2. B
    A rigid internal ring is mounted directly onto the wheel rim inside the tire.
  3. C
    All military combat vehicles must replace pneumatic tires with solid non-pneumatic tires to withstand battlefield threats.
  4. D
    Conventional pneumatic tires rapidly deflate and collapse when punctured by debris or ballistics.

Cevap

Run-flat tire inserts enable tactical vehicles to keep moving even after sustaining severe tire damage.
The passage opens with an explicit topic sentence stating that run-flat tire inserts allow tactical wheeled vehicles to maintain mobility after sustaining severe damage. The rest of the paragraph describes how these inserts function to achieve that specific outcome, making this option the definitive main idea.

Adım Adım Çözüm

1
Locate the topic sentence containing the central claim of the passage.
The opening sentence explicitly asserts that run-flat tire inserts are critical safety components allowing tactical wheeled vehicles to maintain mobility following severe damage.
Expository paragraphs frequently state their central point in the first sentence before providing supporting descriptions.
2
Evaluate the remaining sentences to verify if they support this central claim.
The subsequent sentences explain the problem of tire deflation and describe how the internal ring mechanically supports the vehicle during pressure loss.
Supporting details serve to explain and reinforce the main idea rather than replace it.
3
Select the option that directly paraphrases the explicit main idea.
The statement expressing that run-flat tire inserts enable tactical vehicles to keep moving after tire damage matches the core message.
The correct answer must encompass the entire scope of the text rather than isolated facts.
