Final answer:
The sentence is a run-on because it joins two complete sentences without proper punctuation or conjunctions. It can be corrected with a period, semicolon, or a coordinating conjunction with a comma.
Step-by-step explanation:
The sentence in question appears to be a run-on sentence. Run-on sentences occur when two or more complete sentences are joined without proper punctuation or coordinating conjunctions. For example: Margaret Bourke-White was a famous photographer she worked for LIFE magazine during World War II.
This sentence could be corrected by adding a period, semicolon, or a coordinating conjunction and a comma. A correct version could be: Margaret Bourke-White was a famous photographer; she worked for LIFE magazine during World War II. This maintains the sentences as separate ideas but correctly punctuated.
