question:
Passage: I needed to write a school report on tigers , and I decided to visit the library to find a book to use in my research . When I entered the library , I saw hundreds of books on many different shelves and was not sure where to find books on tigers . I asked a librarian for help finding books on tigers . she asked me . I told her I wanted facts and real information so I can write a report . She walked over to a group of shelves labeled Nonfiction and told me that these books all had true facts and pictures , rather than being imaginary stories . Using these codes , all the books on tigers would be in the same place and would be very close to books about other animals . She looked up the Dewey Decimal System code for tigers and wrote it down for me . Walking through the shelves with my code , I saw that the numbers on the spines of the books start at zero and keep getting bigger and bigger . There I saw books about lions , cheetahs , and finally tigers . I found a book that looked like it would be helpful for my report and brought it back to the librarian . She asked me for my library card , and after I handed it to her , she scanned it with her computer . Now the book was checked out in my name so that the library would know who has the book . She handed me the book and told me that I needed to bring it back to the library in two weeks . If I did n't bring it back , I would have to pay a fine for every day I kept it , because other people might want to read the book too . Question: What was the search system? Option1: Dewey Decimal System Option2: Morse code
answer:
Dewey Decimal System
