Here is a question about this article: Investment in the city continued. The William Enston Home, a planned community for the city's aged and infirm, was built in 1889. An elaborate public building, the United States Post Office and Courthouse, was completed by the federal government in 1896 in the heart of the city. The Democrat-dominated state legislature passed a new constitution in 1895 that disfranchised blacks, effectively excluding them entirely from the political process, a second-class status that was maintained for more than six decades in a state that was majority black until about 1930.
What is the answer to this question: Blacks were the majority in South Carolina until what year?
****
So... 1930


Here is a question about this article: Instead, he formulated the spearhead model of evolution, a version of genetic pluralism. According to this model, living organisms themselves have goals, and act according to these goals, each guided by a central control. In its most sophisticated form, this is the brain of humans, but controls also exist in much less sophisticated ways for species of lower complexity, such as the amoeba. This control organ plays a special role in evolution—it is the "spearhead of evolution". The goals bring the purpose into the world. Mutations in the genes that determine the structure of the control may then cause drastic changes in behaviour, preferences and goals, without having an impact on the organism's phenotype. Popper postulates that such purely behavioural changes are less likely to be lethal for the organism compared to drastic changes of the phenotype.
What is the answer to this question: Organisms' goals shift along with which notable genetic process?
****
So... Mutations


Here is a question about this article: Nanjing is an important railway hub in eastern China. It serves as rail junction for the Beijing-Shanghai (Jinghu) (which is itself composed of the old Jinpu and Huning Railways), Nanjing–Tongling Railway (Ningtong), Nanjing–Qidong (Ningqi), and the Nanjing-Xian (Ningxi) which encompasses the Hefei–Nanjing Railway. Nanjing is connected to the national high-speed railway network by Beijing–Shanghai High-Speed Railway and Shanghai–Wuhan–Chengdu Passenger Dedicated Line, with several more high-speed rail lines under construction.
What is the answer to this question: What type of railway lines are now under construction?
****
So...
several more high-speed rail lines
