• A. “When a magnetic field gets severely folded like this, interesting things can happen.”

• B. “The crowded folds of the skirt reorganize themselves, sometimes explosively, into foamy magnetic bubbles.”

• C. “The actual bubbles appear to be self-contained and substantially disconnected from the broader solar magnetic field.”

• D. “When these microscopic cannonballs try to enter the solar system, they have to fight through the sun’s magnetic field to reach the inner planets.”

Which excerpt from the video best demonstrates the central idea? RST.9-10.2, RST.9-10.1

• A. “The two Voyager spacecraft have been travelling away from earth for more than thirty-three years, and they are finally in the outer edge of the solar system.” (0:14-0:20)

• B. “The sun’s magnetic field spins on opposite directions on the North and South Poles, creating a sheet where the two spins meet.” (0:46-0:52)

• C. “The smooth, streamlined look is gone, replaced with a bubbly, frothy outer layer.” (1:20-1:23)

• D. “When they arrive at the bubble region, they slowly move from bubble to bubble until they can reach smooth magnetic field lines, and follow them toward the sun.” (1:31-1:38)
