Students who know the answer can answer below, and the 10 participants who answered correctly will receive 5 reusable cloth masks each!
The correct answer will be announced on Thursday.
Activity Details:
- Each participant can only submit an answer once. If a participant submits multiple answers, the institution will use the first answer as the final answer.
- The organization has the final and binding decision on this event (such as participation qualification, award qualification, award list and award collection arrangement, etc.). In case of any disputes, the agency reserves the right of final decision and interpretation.
