Instructions ›

Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

I wanted to talk a little bit about how waves are formed and the truth is that most of the waves that we see, our coasts, they are formed very far away. There are stones in the middle of the ocean where the wind from the stones tracks the surface of the sea over a large extent of water, and that extent of water is called fetch. So we basically need three ingredients. We need wind, spin, wind duration and the fetch length, and the larger the ingredients, the larger the waves. Right. So we have this area in the middle of the ocean. We will have all of these ways of different sizes getting together that's quite similar to the first image that Killian had in his presentation. So in deep water, the waves travel at the speed that is given only by the size of the waves. So the larger waves travel faster. So think about. Long distance rate. Think about the Olympics and the 10,000 kilometres rather.

Option 3: "Wind, spin, wind duration, and fetch length"

Explanation: This option is correct as it includes all the ingredients mentioned in the text: wind, spin, wind duration, and fetch length. The text states that these are the three essential components needed to form waves, making this option comprehensive and accurate.

Option 1: "Wind, water temperature, and fetch length"

Explanation: This option is incorrect because the text does not mention 'water temperature' as one of the ingredients needed to form waves. The correct ingredients listed in the text are wind, spin, wind duration, and fetch length.

Option 2: "Wind, spin, and wind duration"

Explanation: While this option includes 'wind' and 'spin,' it omits 'fetch length,' which is explicitly mentioned in the text as a necessary ingredient for wave formation. Therefore, it does not fully capture the required components.

Option 4: "Wind, water density, and fetch length"

Explanation: This option is incorrect because it includes 'water density,' which is not mentioned in the text. The correct ingredients are wind, spin, wind duration, and fetch length, thus making this option incomplete.
