General Science and Ability Past Paper 2021

Stars and planets open the General Science and Ability past paper 2021. Q.2 asks candidates to differentiate a star from a planet, explain why semiconductors earn the label “brains of modern electronics”, and describe the most accepted theory of the origin of the universe. Q.3 stays with biology: cells, tissues and organs, transpiration, and double circulation in the heart. Q.4 maps the strata of the atmosphere and the water cycle. Section-B turns practical: a restaurant bill with discount, service charges and GST, an averages puzzle, simple interest on Rs. 60,000, jumbled spellings, and missing numbers in series.
