Luke found a box of photos labeled 1970-1995. Each photo shows his entire extended family. No dates appear on the photos. Luke knows that his grandmother died in 1985 and his uncle was born in 1975. Luke’s sister was born in 1990. How can Luke use this information to sort the photos into four batches? How are Luke’s relatives similar to index fossils? PLEASE HELP
