10. LISTEN AGAIN TO PART OF THE PASSAGE. THEN ANSWER THE QUESTION. 
(Professor)
I don’t have a picture of a soap molecule here today, but what you need 
to know that the soap molecule has a long chain of carbon atoms, a 
much longer chain than the gasoline atom. In fact, soap can have 
anywhere between five and seven carbon atoms in a chain. Oh, wait. Did 
I say five to seven? Oh, excuse me. I meant to say fifteen to seventeen. 
Let me repeat this.
WHY DOES THE PROFESSOR SAY THIS:
 (Professor) 
Oh, excuse me.

Question 2
. Now listen to the passage. 
(Professor) 
So I just wanted to make a quick point about the introduction in the 
textbook chapter on dreams…uh, the one about Freud’s theories, which 
have not really stood up to the test of time. Now, to be fair to Freud, he 
had no knowledge of REM, um, Rapid Eye Movement or Dreaming 
Sleep, when we dream. But now that we can tell when people, and 
animals, are dreaming, there is real evidence that Freud’s theories on the 
origin of dreams can’t be true. 
 
The first and strongest evidence is the fact that mammals seem to 
dream, and babies have longer periods of dreaming sleep than adults.
Neither babies nor animals would be likely to have as many repressed 
desires as an adult human. 
Another incompatibility between the theory that repressed urges provoke 
dreams is the regularity of dreaming sleep. The sleep cycle is pretty 
repetitive, and it seems unlikely that animal emotions would be held in 
check all day long and come up in sleep in such a regular pattern.
Now answer the following question. You have 30 seconds to prepare an answer and 60 
seconds to give your spoken response.
