Preparing for the Party.
A mother and her daughter are cooking dishes for the party. I need your help badly, Mary. There is so much to do for tonight's party — a salad to be prepared, various pies and cakes to be baked, a goose to be roasted, and a lot of other things to be cooked. Please take the mincing machine and mince this bit of meat while I am scraping and slicing the carrots. Will you peel these potatoes and onions? I'll make some potato chips and you set up the rest of the potatoes to boil. When they are soft, mash them with butter and milk. You know that milk must be hot, don't you? So, we'll have mashed potatoes and vegetables with the meat. Please clear the peeling off the table. Now, wash and cut the potatoes and cucumbers, put them on the dish but don't dress with the mayonnaise, we'll do it later. I think that it's time to get out the goose from the oven. Oh, what a perfect smell! I've never yet had such a beautiful golden crust. It makes one's mouth water just to look at it.
Won't you please get me the baking pan? We'll bake a layer cake and a pie with jam filling. I'll beat the eggs for the dough. Look, the rice is boiling over, turn the gas down a little, will you? Now, be a good girl and whip the whites of these eggs. Here is some powdered sugar to mix with the whites when you are through... That's about all. I think. Thank you, dear, you've been a great help to me. Only put the fish jelly into the refrigerator. and then you may be free till evening. Now will you help me in laying the table? The guests will come in an hour. We’ll be twelve altogether, so lay twelve places. Take the dishes for refreshments from the sideboard and put them on the table. Now fetch the wine glasses — one for each cover. We shan't uncork the bottles. That's a man's job, of course, but get the corkscrew ready. Now, while I'm busy in the kitchen reheating some dishes, you open these tins. Here is the tin opener for you.

теперь объяснения.
В первом мы выбрали вариант а, т.к. Земля вращалась, вращается, и будет вращаться вокруг Земли.
Во втором вариант с, т.к. мы знаем точное время, поэтому это не present perfect и не present simple, следовательно остается лишь один вариант.
В третьем действует правило, что, если вначале стоит без отрицания глагол, то в "хвостике" мы вставляем с отрицанием и наоборот + местоимение какое там было.
Удачи в учебе!
