Icebergs generally appear to be mostly white or blue, depending on how the ice reflects sunlight. Ice with air bubbles trapped in it looks white because much of the light reflects off the bubbles. Ice without air bubbles usually looks blue because the light travels deep into the ice and only a little of it is reflected. However, some icebergs in the sea around Antarctica appear to be green. One team of scientists hypothesized that this phenomenon is the result of yellow-tinted dissolved organic carbon in Antarctic waters mixing with blue ice to produce the color green. Which finding, if true, would most directly weaken the team's hypothesis?

Difficulty: Hard

White ice doesn't change color when mixed with dissolved organic carbon due to the air bubbles in the ice.

Dissolved organic carbon has a stronger yellow color in Antarctic waters than it does in other places.

Blue icebergs and green icebergs are rarely found near each other.

Blue icebergs and green icebergs contain similarly small traces of dissolved organic carbon.
