DineOutHelper is a mobile application that people can use to select a restaurant for a group meal. Each user creates a profile with a unique username and a list of food allergies or dietary restrictions. Each user can then build a contact list of other users of the app. A user who is organizing a meal with a group selects all the members of the group from the user's contact list. The application then recommends one or more nearby restaurants based on whether the restaurant can accommodate all of the group members' allergies and dietary restrictions. Suppose that Alejandra is using DineOutHelper to organize a meal with Brandon and Cynthia. Which of the following data is not provided by Alejandra but is necessary for DineOutHelper to recommend a restaurant for the group? I. Brandon's contact list II. Information about which restaurants Brandon and Cynthia have visited in the past III. Information about which food allergies and dietary restrictions can be accommodated at different restaurants near Alejandra A. II only B. III only C. II and III D. I, II, and III

B. III only

RunRoutr is a fitness tracking application for smartphones that creates suggested running routes so that users can run with each other. Upon downloading the application, each user creates a username, a personal profile, and a contact list of friends who also use the application. The application uses the smartphone's GPS unit to track a user's location, running speed, and distance traveled. Users can use the application to review information and statistics about their previous runs. At the beginning of a run, users indicate the distance they want to run from their current location, and the application suggests a running route. Once a user accepts a suggested route, the application shares the suggested route with other compatible users in the area so that they can run together. Users are considered compatible if they are on each other's contact lists or if they typically run at similar speeds. A basic RunRoutr account is free, but it displays advertisements that are targeted to individual users based on data collected by the application. For example, if a user's running route begins or ends near a particular store, the application may display an advertisement for that store. Users have the ability to pay a monthly fee for a premium account, which removes advertisements from the application. Which of the following data must be collected from a user's smartphone in order for RunRoutr to suggest a running route? A. Available running routes near the user's home B. The current time C. The starting location of the user's previous run D. The user's geographic position

D. The user's geographic position
