Final answer:
Kendra would find the most information about the Lost Battalion in a book on World War I, as it would provide detailed accounts and context surrounding the event. The correct option is A
Step-by-step explanation:
Kendra would find most of the information about the Lost Battalion in a book on World War I. The Lost Battalion refers to the 1st Battalion, 308th Infantry Regiment, which was part of the 77th Division during World War I. They were famously surrounded by German forces in the Argonne Forest in 1918. While a book specifically on the Argonne Forest might have some information, a comprehensive source would be found in a book covering World War I as a whole, which would provide context and detailed accounts of the event. Newspapers from 1914 would be too early to cover the Lost Battalion (as the United States entered the war in 1917), and a dictionary would only provide a definition of the word 'lost,' not historical context.
