Distinguish between the usage of the present perfect continuous tense and the present perfect tense.

You will have a maximum of 1 minute to answer each question (however, you must both provide the correct answer and explain your answer). If you can answer and explain correctly, your team will get two points. However, if your team only provides the answer without explaining or exceeds the explanation time limit, the opportunity will be given to another team. In this case, the points will be split in half (1 point for each part/team). The game will be played cumulatively; if a team gets all the points, they advance; otherwise, the opportunity goes to the next team. Members who have already answered are not allowed to answer for another team. The team with the highest score wins. Good luck!
