Read the following passage. Decide if the statements from 17 to 20 are True or False, and choose the correct answers (A. B, C or D) for questions 21 and 22.

Where did your water come from before it arrived in your kitchen? Is your glass of water as new as this morning or as old as the dinosaurs? Is it even older than the dinosaurs? Water on Earth is always moving round and round, like a wheel turning. This is called “the water cycle," and it has no beginning or end. But to talk about it, we must choose a place to begin. We will start with the oceans, the largest bodies of water on Earth.

In this part of the cycle, the sun heats the Water In the oceans, and then the warm water evaporates into the air. The water In the air eventually comes together to form very large clouds. Wind then moves the clouds over the land. When clouds finally meet cold air, the water comes down in the form of rain or snow.

Some of this rainwater will stay on the land, but most of the water goes down into rivers and streams. Finally, it goes back to the oceans, where the cycle begins again.

The water cycle is billions of years old. So, think again about how old that water in your cup is. It’s much, much older than you thought.

Which word has the underlined part pronounced differently from that of the others?
