A black hole anchors the General Science and Ability past paper 2023. Q.2 opens Section-A with ceramic and nano-ceramic materials, then asks how black holes form and how astronomers discover them. Q.3 asks why the bat and the whale count as mammals, explains urine formation, and returns to hepatitis. Q.4 separates fog from smog and maps the layers of the atmosphere, the layer where auroras form, and the orbit zone of satellites.
