Section 4

I

How has your research been going/since then?//

K

I’ve made improvements/to the photocatalyst/so that water can be purified/in 15 minutes.// However,/no matter how well my research goes,/it’s just a part of the solution/to the world’s water problem.//

I

What else/is needed to solve the problem?//

K

Scientists in the world/will have to work together.// They also need to cooperate with governments/and other organizations.// Alone,/a single drop of water/can’t do much.// But when many drops come together,/they can sustain life/on our planet.// Just as water drops come together/to form oceans,/I believe/that we all must come together/when we tackle this global problem.//
