For the first question regarding the type of pattern used in the artwork, the correct response would depend on the specific characteristics of the artwork in question. However, based on typical definitions:
- **Random**: elements are placed without a specific order.
- **Alternating**: elements are repeated in a systematic manner, but they change in each repetition.
- **Normal**: does not specifically refer to a pattern type, so it might not be the correct option in this context.
You should choose **alternating** if the artwork has a repeated pattern that changes with each occurrence.
For the second question about an object or element that is repeated in an artwork, the correct response is **motif**. A motif is indeed a recurring element that has significance within a work.
