Answer is Right!
Answer is Wrong!
The correct answer is C. soothing.
The movement of the train was so soothing that all the passengers slept very well. The rocking motion of the train is very relaxing and can help people to fall asleep. Additionally, the sound of the train’s wheels on the tracks can be very calming.
The other options are not as likely to make people sleepy. Option A, distracting, is the opposite of soothing. Option B, noisy, could potentially keep people awake. Option D, fast, could also keep people awake, as it could be exciting or stimulating.
In conclusion, the correct answer is C. soothing. The movement of the train was so soothing that all the passengers slept very well.
