p. 333 Q 2. Which word in the paragraph below means "capable of bending easily without breaking."

(Spell it correctly in your answer for credit)

So why can't a dog speak? The big difference is the dog's anatomy, or the structure of its body. A dog's mouth is not as flexible as a human's. A dog can't move its mouth to make it smaller or roll its tongue in different positions. So after the air passes through the vocal cords, the dog can't change the sound very much.

Answer explanation

The word is flexible. The sentence after, "A dog can't move its mouth to make it smaller or roll its tongue in different positions," addresses the dog's inability to move its mouth into different positions.

p. 334 Q 3.

What information in "What Are Vocal Cords?" helps the reader understand why dogs can't speak, as stated in "Dogs and Birds: Making Noise"?

• A People can make higher sounds by tightening the vocal cords and lower sounds by relaxing the cords.

• B Even though we don't often think about how we say words and sentences, we don't learn to speak automatically.

• C People move their mouths to form words from the sounds made by the vocal cords.

• D The vocal cords of humans are not like the strings on a guitar because they have a V-shape.

Answer explanation

C is correct. It supports the idea that dogs can't speak because they can't move their mouths to form words, as people can.

A is about forming sounds, not forming words.

B does not relate to the reason why dogs can't form words.

D doesn't show a difference between humans and dogs. Like humans, dogs have vocal cords.
