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?
