Question

Read the excerpt from a passage about wind turbines.

The blades rotate based on wind speed and direction, so the sound isn’t consistent. There are swooshes, thumps, and then silence. The changing rhythm of the noise captures people’s attention, and it is harder to ignore. People living in rural areas expect it to be quiet, so they may be more aware of the noise. For those who live near a wind farm, their sleep patterns may be disrupted by the noise. And for those who live closer to turbines the sleep interference is worse. The lower frequency of the noise from wind turbines tends to be more bothersome. It has been associated with fatigue, sleeplessness, and irritability.

Which line from the excerpt best supports the idea that the sound from wind turbines is more than just annoying?


A) "The changing rhythm of the noise captures people’s attention, and it is harder to ignore."

B) "It has been associated with fatigue, sleeplessness, and irritability."

C) " The blades rotate based on wind speed and direction, so the sound isn’t consistent."

D) "People living in rural areas expect it to be quiet, so they may be more aware of the noise."

Answer 1

B

Step-by-step explanation:

Showing that the turbines have been associated with sleeplessness and fatigue is demonstrating that they are more than just annoying, they actually interrupt people's sleep.

Answer 2

The correct answer is letter "B".

The line from the excerpt that best supports the idea that the sound from wind turbines is more than just annoying is:

"It has been associated with fatigue, sleeplessness, and irritability."

Step-by-step explanation:

Scientific studies have shown that wind turbines cause harm to humans and animals, especially when the facilities are too close to inhabited areas. Wind turbines produce very low frequency sounds below 20 Hz called infrasounds. The infrasound cannot be heard but they are captured and detected without our feeling, by our auditory system. The electrical power is detected by the low frequency zone of the ear, which is extremely sensitive.

Some symptoms suffered by people living near the wind turbine's location areas are: fatigue, sleeplessness, irritability, instability, imbalance, vertigo, nausea, dizziness, sensation of pressure in the ear or possible hearing loss induced by low frequency sound.
