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. Businesses have the ability to target advertisements to different groups of people who use RunRoutr. Which of the following groups is LEAST likely to receive targeted advertisements?
Individuals who sign up for a premium account

The following algorithm is intended to determine the average height, in centimelers, of a group of people in a room. Each person has a card, a pencil, and an eraser. Step 2 of the algorithm is missing. Step 1: All people stand up. Step 2: (missing step) Step 3: Each standing person finds another standing person and they form a pair. If a person cannot find an unpaired standing person, that person remains standing and waits until the next opportunity to form pairs. Step 4: In each pair, one person hands their card to the other person and sits down Step 5: At this point, the standing person in each pair is holding two cards. The standing person in each pair replaces the top number on their card with the sum of the top numbers on the two cards and replaces the bottom number on their card with the sum of the bottom numbers on the two cards. The sitting partner's card is discarded. Step 6: Repeat steps 3-5 until there is only one person standing. Step 7: The last person standing divides the top number by the bottom number to determine the average height. Which of the following can be used as step 2 so that the algorithm works as intended?
Step 2: Each person writes their height, in centimeters, at the top of the card and writes the number 1 at the bottom of the card.
