                     COMPETENCY-BASED QUESTIONS

                     1.  While  working on a city  development  project, Ishaan uses  the  data  with an AI system  to
                        analyse data on traffic, pollution and population growth. This helps his team decide where to
                        build new roads, schools and parks and also identifies flood-prone areas to improve safety

                        measures. Which type of data is being used here to support urban planning and sustainable
                        city development?
                     2.  When Aarav feeds an AI program with hundreds of pictures of camels and giraffes, the system

                        studies their features to tell them apart. Later, when he watches videos online, the app starts
                        suggesting  new ones  similar to  what he has already  seen. Which concept  helps Artificial
                        Intelligence analyse large amounts of numerical data, learn from it and make predictions
                        based on patterns?

                                                                                              Statistical Data
