22. C

The man says …it’s better to do the reading before the lectures…. The woman says Yeah, you ‘re right. I guess have some catching up to do. You can predict that she will read the textbook before the next lecture. (2.4)

23. D

The class will be creating their own mural. The instructor says I know you ’re all excited about our class project. But before we get started on the design of our mural, let s review some of the technical requirements for murals. (2.3)

24. A, C

In planning a mural, the position of the observer should be considered: We want people to take in our mural—all of it—from a moving position, since they ’ll be observing it as they walk through the lobby to the elevators. The architecture of the room should also be considered: A mural is an integral part of the building. If it’s painted in an existing building, like ours will be, it should be planned to fit into the architectural design…. (2.2)

25. D

The instructor means that a mural is an expression of the building’s character. The instructor points out that the term “mural” suggests a feeling, nature, or quality that is appropriate to the architecture, and that a mural is an integral part of the building. This description relates to the essential character of the building. (2.4)


Yes: Moisture seeps through the wall and dissolves salts in the wall material: When water leaks through a wall, it may dissolve the salts that are in the building materials,

No: The plaster dries more quickly than the paint: Not mentioned in the discussion.

No: An air space between the interior and exterior walls insulates the mural: …an air space of one-half to one inch between the outer and inner walls. That’s enough to protect our mural from moisture….

Yes: Dried salt deposits form a white film on the mural: When the moisture dries, the salts are deposited in the form of white, moldy-looking film on the surface of the plaster. (2.6)

27. A

The student says We could create an air space between the outer wall of the building and the plaster; The air space would have an insulating effect. What I mean is, it would slow down any temperature changes on the plaster. (2.2)

28. C

The instructor’s purpose is to explain how to create an insulating air space between the outer and inner walls. The instructor describes how to build another wall on top of strips of wood attached to the inside surface of the wall. The mural will be painted on this new wall. (2.3)

29. D

The professor mainly discusses how seeds germinate and grow. The professor says Our study of the life cycle of a plant usually starts with the germination of a seed; The germination of a seed is a critical stage in the plant’s life cycle. (2.1)

30. A

The professor says Heredity determines what the plant will look like, how it will grow, and what kind of seeds it will bear. Inside the seed is all the genetic information the plant needs to grow to maturity. (2.2)

31. B

The professor’s purpose is to give an example of an environmental cue. The professor explains that some seeds require a specific environmental cue for germination. Then he gives the example of a heavy rainfall, an environmental cue that causes desert plants to germinate. (2.3)

32. B, D

Water is an environmental factor that seeds require for germination: Water is a basic requirement, and no seed will germinate unless it absorbs water. Another factor is the proper temperature: Germination also requires a certain combination of temperature and light…; Each plant species has an ideal temperature at which the largest number of seeds will germinate. (2.2)

33. C

The professor says For a seed to sprout and grow, it needs a great deal of energy. Seeds get this energy by converting the energy of their stored fuel molecules…. (2.2)

34. C-B-D-A

The professor says (1) When the embryo takes in water, it often swells to several times its original size; (2) The first organ to emerge from the germinating seed is the embryonic root. The root pushes outward into the soil…; (3) The tip of the shoot has to break through the soil surface; (4) …it unfolds its solar collectors, its first leaves; …now it draws most of its growth energy directly from the sun. (2.6)

35. A

38. B, D

The professor suggests that the student focus on a few essential steps of organizational redesign: What you need to do is narrow this down to the three or four …or five steps that you believe are necessary for redesigning an organization. She also suggests that he support his points with examples from a real organization: It would also be good to illustrate your points with examples from a real organization…; You need to focus on three or four essential steps for organizational redesign and then illustrate them with a real-world example of what a real business could do, or has done, along these lines. (2.2)

39. B

The student’s purpose is to give an example that he might discuss in his paper. He says I actually thought of an example, but I don’t know if it’s right for this paper. Its a nursery business…; It’s a business I actually know. My uncle is the superintendent there. (2.3)
