| Some not technically true; Les Paul just attached a mic to a guitar but didn't really invent electric guitars... The radio was invented by Tesla according to the USA and Marconi according to the UK so both should be accepted (and in my opinion others were earlier too); there were 22 inventors of the light bulb before Edison so that's ambiguous; Bell didn't invent the telephone but patented it first; in terms of the aeroplane (19th century onwards) or airplane (1907 onwards), the Wright Brothers actually called it a "Flying Machine" and therefore all three should be accepted - but overall good choices and maybe accept other individuals or find a good internet source? |
