| Q | a | Which of the following best describes the following picture? |
| y | When the wind is against the wind, the blades will not move. | |
| e | When the wind blows from the left, the blades create drag. | |
| v | y | When the wind passes over the blade, it generates a lifting force. |

| Q | r | When lightning strikes a hollow turbine blade, it rapidly heats the air inside to over 30,000 ºC. The air expands explosively, and the blade shatters. To protect them, the blades can be fitted with a special defense, copper tips. So, it can attract lightning as well as dissipate heat as fast as possible.According to this paragraph, what does “it can attract lightning as well as dissipate heat as fast as possible.” mean? |
| o | The wind turbines can be recharged with lightning through copper tips. | |
| v | d | The wind turbine can be protected by copper tips by dispersing high temperatures. |
| d | Copper tips will know which blade of a wind turbine needs to be charged. | |
| a | Copper tips will collect the power of lightning to convert it to electricity. | |

| Q | e | According to the audio file about the battery of Formula E racing car, why does the narrator say, “the technology and the chemistry within them is a bit more bespoke”? |
| y | The battery is the same as a normal battery. | |
| e | The battery can pass the message to users. | |
| . | The battery is said to be long-lasting. | |
| v | r | The battery is specially designed. |

| Q | d | Here are some copper windings that carry the current, and these are wrapped around an iron core. Which of the following best describes the following picture? |
| v | d | The current in the copper windings generates a magnetic field. |
| a | The magnetic field is a racetrack for Formula E racing. | |
| y | The magnetic field can efficiently attract foreign objects on the track. | |
| e | The advice helps the rotating magnetic field automatically generated. | |
