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: Jack has to mow his dad 's lawn once a week . He decides this week he will do it on the weekend in the morning . Since he has baseball practice on Sunday , he wants to cut the grass on Saturday . It is a nice riding one , with a big red paint job . He checks to see if it has any gas , fills it with some gasoline from the container in the shed , and pulls it out of the shed carefully onto the grass . He starts with the back yard , because it is the biggest part of the lawn . He puts his cap on , starts the engine by pressing the start button , and the engine roars to life . The lawn mower rolls forward , and Jack tries to go in straight lines as he goes across the lawn , front and back yards . By the time he is finished , the lawn has nice straight lines where he mowed the grass , and the grass is short and neat . Question: Who jumped on the seat? Option1: Jack's dad Option2: Jack
