Letter: Fast answers

Sir: Our Dad read the article on encyclopaedias and computer CD- Roms (13 January), and then set us the three questions that the two researchers were given. We achieved all the questions in less than three minutes. We think most children between six and 12 who have a PC at home could do as well or better. We think your researchers must have been either very young (under four) or very old (over 16).
