Example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day.

New input case for you: Question: Did the close friend who inspired Kracaw to pursue psychology as her major enrolled in UC Berkeley the same year as she did? Passage:Kracaw graduated from high school in 1915. In the same year, her family left Colorado and moved to Orland, California, since the lower elevation there was expected to benefit her father's health. However, her father suffered setbacks in his business, and facing both blindness and tuberculosis, he committed suicide in 1917. Kracaw enrolled at the University of California, Berkeley, in 1915. She considered majoring in economics and English literature before deciding on psychology. She made a number of lifelong friends during her undergraduate years, including Jean Macfarlane, whose interest in psychology drove Kracaw to select that discipline for her major. She graduated cum laude in 1921, and began graduate study at UC Berkeley. Her Master's thesis studied ten families in San Francisco that had been clients of a juvenile court. She volunteered as a probation officer, and was required to meet and report on the families she was studying. She would later write that she struggled to be objective in writing about these families. Kracaw received her Master's degree in clinical psychology in 1920.
