Example input: 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
Example output: once
Example 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.
Q: Passage: Today I decided to visit a natural history museum . The museum was close to my house and weather was nice outside , so I decided to walk to the museum . I took me about 20 minutes to the walk to the museum . This museum required you to pay a fee to enter it . I went up the counter where a museum employee was sitting and talked to them . They told me how much it cost to enter and I paid them . They put a stamp on my hand so if I wanted to leave and return I could do so by showing them the stamp , and told me I could now enter the museum to look around . I started by exploring the bottom floor first . After I saw everything on the first floor , I went upstairs to the second floor where I learned all about the cavemen and how they lived . Once I was done exploring the whole museum , I left and walked back home . Question: What was seen first? Option1: the first floor Option2: the second floor
A:
the first floor
