Practice one SAT question at a time

Questions come from the Bluebook question bank.

While researching a topic, a student has taken the following notes:

  • Gravitational waves are powerful ripples that originate in deep space and eventually pass through Earth.
  • The Laser Interferometer Gravitational Wave Observatory (LIGO) is a physics study that began in 2002.
  • LIGO’s goal is to detect and analyze gravitational waves.
  • LIGO uses a pair of massive gravitational wave detectors called interferometers that are thousands of miles apart.
  • In 2015, for the first time in history, LIGO researchers detected a gravitational wave passing through Earth.

The student wants to present LIGO’s aim and methodology. Which choice most effectively uses relevant information from the notes to accomplish this goal?
