Final answer:
The student should search in a zigzag or spiral pattern to pick up the trail of a wounded animal.
Step-by-step explanation:
If you are searching for a wounded animal and you lose the blood trail, you should search in a Zigzag or Spiral pattern and try to pick up the trail again. These patterns can help you cover a larger area while still maintaining a systematic search. For example, if you search in a zigzag pattern, you can move back and forth across the area, covering the entire space, while a spiral pattern involves moving in a gradually expanding circle from the initial point.
