Architects and sound engineers routinely use sound-absorbing materials on ceilings and walls. In addition, they have sometimes tried to create optimal acoustics by building the ceilings and walls of concert halls with rippled or (i) $\(\qquad\)$ surfaces, so that the sound is reflected and (ii) $\(\qquad\)$ at many angles.
| Blank (i) | Blank (ii) |
|---|---|
| A. invariably rigid | D. distorted |
| B. highly polished | E. diffused |
| C. slightly undulating | F. auditory |

The first blank has to be similar to a rippled ~ wavy surface (smth actually like this: ~~~~ 
) so slightly undulating matches the requirement.
The second blank needs a word that can explain the sound quality must remain intact with reflection. As sound waves reflect from the rippled surface, they are dispersed (spread out) at many angles.

The correct answers are C and E. For the first blank, the phrase with the closest meaning to rippled is what you're looking for. Eliminate choice A, "invariably rigid," which means the opposite of rippled, and choice B, "highly polished," which makes no sense in the sentence. For the second blank, choice E is correct because a rippled surface would diffuse the sound "at many angles" to create the desired effect. Distortion is the opposite of the desired effect, so choice D is incorrect. Choice F should also be eliminated because auditory means "related to the process of hearing," not "able to be heard" or audible.
