Input: Read this: Chinese men entered the United States as laborers, primarily on the West Coast and in western territories. Following the Reconstruction era, as blacks set up independent farms, white planters imported Chinese laborers to satisfy their need for labor. In 1882, the Chinese Exclusion Act was passed, and Chinese workers who chose to stay in the U.S. were unable to have their wives join them. In the South, some Chinese married into the black and mulatto communities, as generally discrimination meant they did not take white spouses. They rapidly left working as laborers, and set up groceries in small towns throughout the South. They worked to get their children educated and socially mobile.
Question: What act allowed Chinese workers in the U.S. to have their wives join them?

Output: unanswerable


Input: Read this: Systematic botany is part of systematic biology, which is concerned with the range and diversity of organisms and their relationships, particularly as determined by their evolutionary history. It involves, or is related to, biological classification, scientific taxonomy and phylogenetics. Biological classification is the method by which botanists group organisms into categories such as genera or species. Biological classification is a form of scientific taxonomy. Modern taxonomy is rooted in the work of Carl Linnaeus, who grouped species according to shared physical characteristics. These groupings have since been revised to align better with the Darwinian principle of common descent – grouping organisms by ancestry rather than superficial characteristics. While scientists do not always agree on how to classify organisms, molecular phylogenetics, which uses DNA sequences as data, has driven many recent revisions along evolutionary lines and is likely to continue to do so. The dominant classification system is called Linnaean taxonomy. It includes ranks and binomial nomenclature. The nomenclature of botanical organisms is codified in the International Code of Nomenclature for algae, fungi, and plants (ICN) and administered by the International Botanical Congress.
Question: How did Darwin change the grouping pioneered by Linnaeus?

Output: by ancestry rather than superficial characteristics

Input: Read this: As war broke out, Maglione, Tardini and Montini were the main figures in the Vatican's State Department, as despatches originated from or addressed to them during the war years.[page needed] Montini was in charge of taking care of the "ordinary affairs" of the Secretariat of State, which took much of the mornings of every working day. In the afternoon he moved to the third floor into the Office of the Private Secretary of the Pontiff. Pius XII did not have a personal secretary. As did several popes before him, he delegated the secretarial functions to the State Secretariat. During the war years, thousands of letters from all parts of the world arrived at the desk of the pope, most of them asking for understanding, prayer and help. Montini was tasked to formulate the replies in the name of Pius XII, expressing his empathy, and understanding and providing help, where possible.
Question: During what time was Montini responsible for the communications of the Vatican?

Output:
war years
