[EX Q]: Passage: Today I decided to make vegetable soup for lunch , so I needed to chop a bunch of vegetables . I went to my fridge and pulled out carrots , celery , and onion . I washed all of my vegetables in my sink and dried them with a paper towel . I decided to start with my carrots first . I took out my wooden cutting board and a sharp knife . Then I chopped off the top and bottom of the carrot and threw those pieces away . I cut the carrot in half lengthwise and then chopped it into smaller , bite size pieces . Then it was time to cut the celery . I cut off the top and the bottom of the celery and threw those pieces away . Just as I did with the carrot , I first cut the celery in half length wise , then chopped it into smaller bite size pieces . I then peeled off all the dried brown skin on my onion and chopped off the top knot and the bottom knot and threw those away . I cut my onion in half , then in half again and half again , repeating the process until I had small sized pieces of onion . I added my onion to the soup pan and added some water and seasonings to make my soup . Question: When did they put the pieces in their soup pan? Option1: after preparing the pieces Option2: before chopping in the pieces

[EX Q]: Passage: There are a lot of different ways to get around town . One of my favorite ways to get anywhere I need to go is by using the underground . If I 'm leaving from home , I usually walk to the station that is nearest to my house . Some stations have people working in ticket booths . Riders give the cashier money and the cashier gives the rider a ticket . Other stations have automatic machines where riders can put in the money or use a credit card and a ticket is dispensed . When the doors open , some riders will disembark . Once the coast is clear , you can go through the doors to the train and find your seat . Beware , though ! You have to be quick ! If you move too slow , the train doors may close and you 'll have to wait for the next train to get to where you want to go ! Question: What do they need to ride the train? Option1: Some money Option2: a ticket
[EX A]:
a ticket
