While researching a topic, a student has taken the following notes:
· The Colosseum in Rome is an ancient amphitheater built in 70-80 CE.
· It was used for gladiatorial contests and public spectacles, such as animal hunts and mock sea battles.
· The Colosseum could hold up to 50,000 spectators.
· The Odeon of Herodes Atticus is a stone theater built in Athens in 161 CE.
· It was primarily used for music concerts and theatrical performances.
· The Odeon could accommodate around 5,000 spectators.
The student wants to highlight a key difference between the Colosseum and the Odeon of Herodes Atticus. Which choice most effectively uses relevant information from the notes to accomplish this goal?
