3 mark for review
which of the following data is not provided by alejandra but is necessary for dineouthelper to recommend
a restaurant for the group?
i. brandons 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 only
d i, ii, and iii

Explanation:

• I. Brandon's contact list: This is provided by Alejandra as she selects group members from her contact list (which would include Brandon's details as part of the group).
• II. Information about which restaurants Brandon and Cynthia have visited in the past: There is no indication in the problem description that Alejandra provides information about past - visited restaurants. The app recommends restaurants based on allergies/restrictions and proximity, not past visits.
• III. Information about which food allergies and dietary restrictions can be accommodated at different restaurants near Alejandra: Alejandra is using the app to organize a meal with Brandon and Cynthia. The app needs to know the group's (including Brandon and Cynthia's) allergies and dietary restrictions (which Alejandra would input as part of building the group profile) and the proximity of restaurants (since she is organizing the meal, her location - related restaurant proximity is relevant).

Answer:

C. II and III only
