invent doubt mention website all of a sudden
It is often difficult to decide on the inventor of certain inventions. This is because sometimes a few people may _________ things which are nearly the same. It’s hard to tell who came up with the idea first. Some inventions can also lead to other inventions ________________. So some people __________ whether the inventor came up with the idea himself or herself. They think that the inventor used someone else’s idea to create his or her invention. That is why books or ___________ usually _______________ more than one inventor when giving information about inventions.
