Read the first three paragraphs of the article. Select the sentence that BEST supports the conclusion that the Great Pacific Garbage Patch is rapidly becoming larger.

• Twice the size of Texas, the floating mass is up to 16 times larger than previously thought.

• According to scientists who performed an aerial survey, it is carrying about 79,000 metric tons of plastic.

• The study reveals that this plastic blight in the Pacific Ocean is still growing at what the researchers called an "exponential" pace.

• The concentration of floating plastic in the patch ranges from tens to hundreds of kilograms per square kilometer.

Which piece of evidence BEST explains why trash has accumulated in the ocean?

• Humans manufacturing and quickly discarding plastic products has caused the garbage patches to grow

• Recent studies show that biofouled plastic can attract fish and seabirds and end up in the food chain.

• Since they're fairly cheap and easy to replace, those nets can then float through the ocean.

• None of this, of course, counts all the plastics that may have sunk to the bottom of the ocean.
