Here is a question about this article: Active solar techniques use photovoltaics, concentrated solar power, solar thermal collectors, pumps, and fans to convert sunlight into useful outputs. Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered supply side technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies.
What is the answer to this question: What does an active solar technique do?
****
So... increase the supply of energy

Here is a question about this article: Malaysia-based Yazhou Zhoukan conducted an interview with former researcher at the China Seismological Bureau Geng Qingguo (), in which Geng claimed that a confidential written report was sent to the State Seismological Bureau on April 30, 2008, warning about the possible occurrence of a significant earthquake in Ngawa Prefecture region of Sichuan around May 8, with a range of 10 days before or after the quake. Geng, while acknowledging that earthquake prediction was broadly considered problematic by the scientific community, believed that "the bigger the earthquake, the easier it is to predict." Geng had long attempted to establish a correlation between the occurrence of droughts and earthquakes; Premier Zhou Enlai reportedly took an interest in Geng's work. Geng's drought-earthquake correlation theory was first released in 1972, and said to have successfully predicted the 1975 Haicheng and 1976 Tangshan earthquakes. The same Yazhou Zhoukan article pointed out the inherent difficulties associated with predicting earthquakes. In response, an official with the Seismological Bureau stated that "earthquake prediction is widely acknowledged around the world to be difficult from a scientific standpoint." The official also denied that the Seismological Bureau had received reports predicting the earthquake.
What is the answer to this question: What did this report warn about?
****
So... significant earthquake in Ngawa Prefecture

Here is a question about this article: Heritage buildings constructed during the Qutb Shahi and Nizam eras showcase Indo-Islamic architecture influenced by Medieval, Mughal and European styles. After the 1908 flooding of the Musi River, the city was expanded and civic monuments constructed, particularly during the rule of Mir Osman Ali Khan (the VIIth Nizam), whose patronage of architecture led to him being referred to as the maker of modern Hyderabad. In 2012, the government of India declared Hyderabad the first "Best heritage city of India".
What is the answer to this question: What type of heritage architecture is mainly displayed in Hyderabad?
****
So...
Indo-Islamic architecture
