Teacher: Now, understand the problem? If you are still confused, see the following 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: once
Reason: 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 instance: Passage: After I had selected a DVD disk for my collection that contain the movie that I wanted to play , I removed the disc from the container , and flipped it over to the reflective side to see if there were any scratches or fingerprints that would interrupt the movie while it would be playing in the DVD player . I used a cotton ball that had been slightly soaked in rubbing alcohol to clean the reflective surface of the DVD , wiping side to side and up and down instead of in a circular pattern in order to avoid deepening any pre-existing scratches . Once I have removed all of the fingerprints and smudges , I used a dry paper tile to remove the excess alcohol and any strands that may have come off the cotton ball . I push the open button to release the cartridge that holds the DVD disc inside of the player . When the cartridge was ejected , I saw that there was a DVD that had already been inside the player , so I removed the DVD from the player , and placed it to the side . The DVD containing the movie that I wished to watch was in my hand , and I placed it into the same cartridge I had just removed the other DVD from . I then pushed the open button on the player again , and the cartridge automatically retracted back into the player with the DVD . As I heard the DVD player spinning the disc , I picked up the remote control to get ready to push play once the video had finished loading . Question: What did they push on the DVD player? Option1: the open button Option2: fast-forward
Student:
the open button
