Frequently asked questions
What kind of questions appear in Inventions MCQs?
Inventions MCQs usually ask who invented a device, who discovered something, which country or company achieved a notable first, and who is known as the father of a field or institution. They are short recall questions that appear in general knowledge papers.
How should I revise inventions for general knowledge tests?
Keep a table with the invention, the inventor and, where useful, the country. Group entries by field, such as communication, transport and medicine, and revise them weekly. Practising MCQs helps because options often include inventors from the same field.
