Q: 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
A: once
Rationale: As mentioned in the passage that I then flip one side of the omelette; it is clear that omelette is flipped one time only.
Q: Passage: Tomorrow was the day of my physics exam . I was feeling confident about it because I had been studying for the past week to prepare . I had tried every different type of studying ; using note cards , reviewing notes , and studying with friends . After a couple of hours of studying I go to sleep to make sure I get plenty of sleep . I wake up the next morning and eat a balanced breakfast to help with my memory a bit . I then head off to school where physics was my first class . He passes out the exam and once everyone has one he tells us to begin . As the exam goes on and I complete some questions easily I 'm left with 2 questions and half the exam time remaining . I do n't have much of an idea on how to do those questions . I start to get nervous and as time ticks down I have to take my best guess and do the parts of the questions that I know for partial credit . I leave the test feeling like I passed with a B. Question: What did they have to study for, for the next day? Option1: physics exam Option2: a biology exam
A:
physics exam
