I was trying this question of a Proficiency English Language Test (fill the blank), and for me both options are possible. But only one is marked as right. I cannot understand why one option would be right over the other. Can someone explain the difference? I looked at dictionaries but I haven't found the answer to my question. anyways, the possible options are either collection or archive.
This is the TEXT
Humans of New York, the photographic __________ of the amazing people roaming around the streets of the Big Apple, was started by Brandon Stanton in the summer of 2010. What began as a journey for a young photographer, exploded into a visual story, twisting its way through the tourist-filled streets, traffic-packed asphalt and winding subway tunnels of this manic city that millions of unique and beautiful individuals call home. Here are the 25 most romantic photos and stories throughout the history of HONY.
Thanks in advance.
