A Gold is heavier than silver. We have English grammar twice a week. The water boils at the temperature of 100 C. They are asking you to come here. We are working in the lab thrice a week. Why aren't you answering? The Sun goes down at the West. How does this magazine called/What is the name of this magazine? When do you eat lunch? That concerns me. The temperature of this cave is always 10 C. It usually snows in winter. I will be teaching you English. I am telling you, you're not right. Tourists are always amazed by the amount of flowers in the cities of Holland.
B You're going to be late, if you won't take a taxi. I am not leaving, until you are coming back. While is going to be in her room, I am going to go down. I am going to get married when I will be 25. It is going to be midnight when we will reach Cambridge. I am going to wait while you are checking my documents. I am going to tell you something, but promise me that you will not tell mom about it. I am sure you're going to like him when you will meet. Unless you will say who you are, I won't let you in. If he will promise something, he would definitely keep it. When you're going to arrive, I will be already at home. Unless you won't hurry up, you're going to be late to the lecture.
C I can't tell you if he will come to the meeting, but if he will, he would be presenting his speech. I would like to know, when is your sister going to come to London. I'm not sure if I did it right. I would like to find out when he is going to arrive. Do you know when he is going to be at home? I'm not sure if she would come tomorrow. Nobody knows when he is going to see England next time. I think(?) I won't tell you when he is going to be back home. Nobody expects him to come. Nobody knows what he is going to talk about. It is interesting when he is going to talk to him about it?
