Let me give you an 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
The answer to this example can be: once
Here is why: As mentioned in the passage that I then flip one side of the omelette; it is clear that omelette is flipped one time only.

OK. solve this:
Passage: The ceiling light in my kitchen started to flicker.It was time to change the light bulb . A new package of bulbs was in the junk drawer . Since I only needed 1 bulb I pulled it out and put the package back . I placed the bulb on the back shelf along with a paper towel . Of course , I made sure the light switch was off so I would not be shocked . I climbed the ladder and carefully unscrewed the cover , setting it down on the back shelf . The new bulb screwed in easily . I wiped the cover with my towel and screwed it back , as well . I climbed down the ladder , put it away and disposed of the bulb and towel.When I flipped the switch the bulb came on without a flicker . Question: What did they unscrew and set down? Option1: new light bulb Option2: old light bulb
Answer:
old light bulb
