Which paragraph from the article BEST supports the conclusion that students modified their robots at the pool?
Group of answer choicesCommunication was constant and encouraging as teams guided their ROVs through tasks at the pool's deep end. The challenges required the ROVs to collect debris from within a concentrated area, collect debris floating across a large area, join two SeaPerches together using a pool noodle, and guide ROVs through vertical and horizontal hoops."Keeping cool under pressure and adjusting your ROV as you go" were crucial, noted Liana Gomez, 11. "We were learning to think through problems in a real-world situation.""I thought we'd come to the pool and everything would work perfectly," said Vivian Kocsis, 12. "It didn't." Some ROVs sank, some tilted to one side and some had control issues. ROVs with floors often needed adjustment so openings were at the right scooping level. Students patiently tackled these problems onsite."We had to drill holes in the pipes to allow air and water in so it wouldn't just float on top," said Jane Naegele, 11, of SS Jaws. The weight of pipes and netting determined flotation needed, while small propellers allowed control of vertical and horizontal movement.

Read the following sentence.
Students wanted to design their robots to remove trash from the ocean.
Which sentence from the article provides the BEST support for the statement above?
Group of answer choicesThe project began with students' concerns about environmental issues, said Alexandria Country Day science teacher Alison McDonald."We had to drill holes in the pipes to allow air and water in so it wouldn't just float on top," said Jane Naegele, 11, of SS Jaws.Teams used drills, pipe cutters, vises and wire cutters in designing "SeaPerch ROVs" — about the size of a 12-inch cube — to collect plastics.The ROV exercise wasn't a competition, but a self-test of each team's design and maneuvering ability.
