Explanation:

To identify mixed constructions, we analyze each part of the passage. The phrase "the purpose of Snapchat was invented" is a mixed construction because "purpose" cannot be "invented"—the correct phrasing would be something like "Snapchat was invented for the purpose of..." or "the purpose of Snapchat is to...". The other sentences ("Snapchat is where users send friends a picture or video that is viewable for only a few seconds" and "The app was created in 2011 and has become a popular way for people to communicate" and "According to the makers of the app... 'with no texting and all the emotion'") are grammatically consistent in their constructions. Wait, no—actually, the error is in "the purpose of Snapchat was invented". Let's re - check: A mixed construction occurs when a sentence starts with one grammatical structure and then shifts to another incompatible one. In "the purpose of Snapchat was invented", the subject "purpose" and the verb "was invented" don't match (you invent a thing, not a purpose). So the mixed construction is "the purpose of Snapchat was invented".

Answer:

the purpose of Snapchat was invented
