Digital SAT Reading and Writing Practice Question #1278

While researching an architectural preservation project, a student has taken the following notes: • The Roman Pantheon was completed around 125 CE under Emperor Hadrian. • Its massive unreinforced concrete dome spans 43.3 meters in diameter. • Roman engineers incorporated lightweight volcanic pozzolana and pumice aggregates near the dome's summit to reduce gravitational shear stresses. • The central oculus (opening) measures 8.2 meters across and serves as the primary illumination source. • Modern structural engineers study the Pantheon to design low-carbon geopolymer cements. The student wants to emphasize how ancient Roman engineering choices directly contributed to the dome's structural stability. Which choice most effectively uses the relevant information from the notes to accomplish this goal?
