Which of the following is the most appropriate title of the passage?
The majestic structures of ancient Rome have survived for millennia. But how did their construction materials help to keep giant buildings like the Pantheon and the Colosseum standing for more than 2,000 years? Roman concrete, in many cases, has proven to be longer-lasting than modern concrete, which can deteriorate within decades. Now, scientists behind a new study say they have uncovered the mystery ingredient that allowed the Romans to make their construction material so durable and build elaborate structures in challenging places such as docks, sewers and earthquake zones. A research team analyzed 2,000-year-old concrete samples from a city wall in central Italy. They found that white chunks in the concrete, gave the concrete the ability to heal cracks that formed over time. The white chunks previously had been overlooked as evidence of poor-quality raw material.

The History of Roman Engineering

The Durability of Ancient Roman Concrete

The Use of Concrete in Modern Construction

The Challenge of Building Structures in Earthquake Zones

The Discovery of a New Type of Concrete in Ancient Rome

가장 적절한 제목은 "The Durability of Ancient Roman Concrete"(고대 로마 콘크리트의 내구성)이다.
지문은 로마 건축물이 오래 버틴 이유를 묻고, "white chunks"(흰 덩어리)가 "the ability to heal cracks"(균열을 메우는 능력)를 주었다고 설명한다. 글 전체가 콘크리트가 오래가는 이유를 다룬다.
"The History of Roman Engineering"은 공학사 전체를 뜻해 범위가 너무 넓다.
"The Use of Concrete in Modern Construction"은 틀리다. 현대 콘크리트는 비교 대상일 뿐이다.
"The Challenge of Building Structures in Earthquake Zones"는 지진 지대가 건설 장소의 예로만 나오므로 맞지 않는다.
"The Discovery of a New Type of Concrete in Ancient Rome"은 틀리다. 새 종류의 발견이 아니라 기존 콘크리트의 성분을 밝힌 내용이다.
