One example: Passage: Omelettes make a great breakfast , and I enjoy making them because they are very easy to cook . First , I get the eggs out and begin cracking them on the side of the bowl and dumping them into the bowl . I normally use two eggs whites and one whole egg to cut the calories . I add some salt and pepper to the mix for flavor . I pour the mixture into the hot frying pan . I make sure that I add some vegetable oil to the pan before I add the eggs though because I do n't want them to stick . As this occurs , I add some cheese or vegetable to the center of the egg mixture . Really , almost any type of cheese or vegetable makes a good omelette . I then flip one side of the omelette over on to itself to seal in the contents in the middle . It is then ready to serve ! Question: How many times is the omelette flipped? Option1: three times Option2: once
Solution is here: once
Explanation: As mentioned in the passage that I then flip one side of the omelette; it is clear that omelette is flipped one time only.

Now, solve this: Passage: Before I vacuum the carpet , I first make sure that all of the kid 's toys are picked up , and will have them do that and put them away . That way I do n't have to pick them up as I get to them . I then get the vacuum out of the closet . I make sure the filter is on tightly , then I put the dirt tray back in . I plug in the vacuum , and turn it on . I start at the edge of the carpet and move the vacuum back and forth , overlapping small areas at a time . I move any furniture that I can not vacuum under . I then unplug the vacuum and wrap up the cord . I put the vacuum back in the closet . Question: When did they plug it in? Option1: After putting the dirt tray back in Option2: before picking up the toys
Solution:
After putting the dirt tray back in
