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

• The University of Oslo in Oslo, Norway, is home to a Foucault pendulum.
• The pendulum consists of a weighted ball that swings at the end of a roughly 14-meter-long cable.
• Like all Foucault pendulums, it dangles from a fixed point that ensures the swing path of the pendulum doesn’t change.
• To an observer, the swing path of a Foucault pendulum appears to change over time because Earth rotates beneath it.
• Foucault pendulums are used as a simple way to provide evidence of Earth’s rotation.

The student wants to explain how a Foucault pendulum provides evidence of Earth’s rotation. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

The Foucault pendulum at the University of Oslo in Oslo, Norway, swings on an unchanging path, but Earth rotates beneath it.

B

A Foucault pendulum, which consists of a weighted ball at the end of a long cable, provides evidence of Earth’s rotation.

C

Though it swings on an unchanging path, a Foucault pendulum appears to change its swing path over time because Earth rotates beneath it.

D

In Oslo, Norway, a Foucault pendulum at the University of Oslo provides evidence of Earth’s rotation.
