Task: Question Answering
Input (English): Passage: I was planning a trip to Hawaii so I needed to make a flight reservation . Once I determined what days I would be in Hawaii , I then began to choose when I should reserve my flight . I picked a day and a half before my first full day in Hawaii for my arrival trip , and then the day after my last full day for the return . I searched online for possible flights that I could take . I decided to select the flights that were more in-line with the timing of my trip rather than the cheapest ones . I selected the flights I wanted and then reserved two seats for me and my wife in business class . Once I got a confirmation of my purchase , I wrote myself a note so that I would n't forget the details of my flight . Question: Where did they enter their preferences? Option1: Hotel search engine Option2: Airline search engine
