Answer:
Let's analyze each sentence:
1. "Leading the field of nonverbal communication, psychologist Paul Ekman studies the significance behind the smallest movements of the face."
In this sentence:
- The -ing modifier is "Leading the field of nonverbal communication."
- It refers to "psychologist Paul Ekman."
- This sentence does not contain a confusing modifier.
2. "People show their discontent or dislike biting the lower or upper lip."
In this sentence:
- The -ing modifier is "biting the lower or upper lip."
- It refers to "People."
- This sentence contains a confusing modifier because it implies that people are showing their discontent or dislike by biting their own lips, which may not be the intended meaning.
3. "On the other hand, indicating love or comfort Ekman noted dilated eyes."
In this sentence:
- The -ing modifier is "indicating love or comfort."
- It refers to "Ekman."
- This sentence contains a confusing modifier because it suggests that Ekman is indicating love or comfort.
4. "Paying attention to facial movements, nonverbal communication can be louder than words."
In this sentence:
- The -ing modifier is "Paying attention to facial movements."
- It does not have a clear reference, which makes it a confusing modifier.
To correct the fourth sentence, you can use the following option:
**Paying attention to facial movements, Ekman found nonverbal communication can be louder than words.**
This revision clarifies that Ekman is paying attention to facial movements and makes the sentence more coherent.
