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:

  • Ducklings expend up to 62.8% less energy when swimming in a line behind their mother than when swimming alone.
  • The physics behind this energy savings hasn’t always been well understood.
  • Naval architect Zhiming Yuan used computer simulations to study the effect of the mother duck’s wake.
  • The study revealed that ducklings are pushed in a forward direction by the wake’s waves.
  • Yuan determined this push reduces the effect of wave drag on the ducklings by 158%.

The student wants to present the study and its methodology. Which choice most effectively uses relevant information from the notes to accomplish this goal?
