The file also contains metadata that describes the date and geographic location where the photo was taken. For which of the following goals would analyzing the metadata be more appropriate than analyzing the data?
i. Determining the likelihood that the photo is a picture of the sky
ii. Determining the likelihood that the photo was taken at a particular public event
iii. Determining the number of people that appear in the photo
iv. Determining the usability of the photo for projection onto a particular color background
