1) Do you mind if I change the channel to the football match?
This sentence is a polite way of asking someone if they have any objection to switching the television channel to the football match. The phrase "do you mind" is used to ask for permission or to check if something is acceptable. To get the answer, you would ask the person directly.

2) If there is an earthquake and I'm inside a building, I'll get (or I ge) under a table or desk.
This sentence describes a conditional action in the event of an earthquake. It states that if there is an earthquake and you are inside a building, you should get under a sturdy table or desk for safety. To answer this question, you would follow the instructions in case of an actual earthquake.

3) If I'm out of a building, I move away from rocks and trees.
Similar to the previous sentence, this one also describes a conditional action. It suggests that if you are outside a building during an earthquake, it is recommended to move away from potential hazards such as rocks and trees. To answer this question, you would follow the recommended safety measures.

4) How long has it been since you last saw him? I saw him two days ago.
This sentence is asking about the duration of time that has passed since the person last saw someone. The response, "I saw him two days ago," indicates that the last meeting occurred two days in the past. To answer this question, you would calculate the time difference between the present moment and the last encounter.

5) Go to the waiting room and wait for your flight to be announced.
This sentence provides instructions for someone who needs to wait for their flight in an airport. The person is advised to go to the waiting room and stay there until their flight is announced. To follow the instructions, you would go to the designated waiting area.
