The problem: Answer a question about this article:
The climatic changes of the late Jurassic and Cretaceous provided for further adaptive radiation. The Jurassic was the height of archosaur diversity, and the first birds and eutherian mammals also appeared. Angiosperms radiated sometime in the early Cretaceous, first in the tropics, but the even temperature gradient allowed them to spread toward the poles throughout the period. By the end of the Cretaceous, angiosperms dominated tree floras in many areas, although some evidence suggests that biomass was still dominated by cycad and ferns until after the CretaceousPaleogene extinction.
What event produced further adaptations during the Jurassic and Cretaceous periods?
****
The answer: climatic changes

Problem: Please answer a question about the following article about John von Neumann:
Von Neumann's habilitation was completed on December 13, 1927, and he started his lectures as a privatdozent at the University of Berlin in 1928. By the end of 1927, von Neumann had published twelve major papers in mathematics, and by the end of 1929, thirty-two papers, at a rate of nearly one major paper per month. His reputed powers of speedy, massive memorization and recall allowed him to recite volumes of information, and even entire directories, with ease. In 1929, he briefly became a privatdozent at the University of Hamburg, where the prospects of becoming a tenured professor were better, but in October of that year a better offer presented itself when he was invited to Princeton University in Princeton, New Jersey.
By the end of 1927 how many papers had Von Neuman written?
A: twelve major papers in mathematics

Here is a question about this article: During the late 1920s and early 1930s, Eisenhower's career in the post-war army stalled somewhat, as military priorities diminished; many of his friends resigned for high-paying business jobs. He was assigned to the American Battle Monuments Commission directed by General Pershing, and with the help of his brother Milton Eisenhower, then a journalist at the Agriculture Department, he produced a guide to American battlefields in Europe. He then was assigned to the Army War College and graduated in 1928. After a one-year assignment in France, Eisenhower served as executive officer to General George V. Mosely, Assistant Secretary of War, from 1929 to February 1933. Major Dwight D. Eisenhower graduated from the Army Industrial College (Washington, DC) in 1933 and later served on the faculty (it was later expanded to become the Industrial College of the Armed Services and is now known as the Dwight D. Eisenhower School for National Security and Resource Strategy).
What is the answer to this question: During the 1920s, for what federal department did Milton Eisenhower work?
****
