Publisher's Synopsis
This pack contains two quiz books and an electronic Bip pen. Each of the two books test the reader's knowledge of the subject matter, with 100 questions. Press the magic pen on one of the multiple choice answers to see and hear if you are correct. If the pen "chirrups" and the green light goes off, then the reader is correct, if it beeps and you see a red light, then try again. In this two-book pack the reader can test their knowledge of great inventions - from paper to jeans, toasters to railways, dates, quantities, people, places, objects and machines, products, materials and techniques - and great discoveries - how the world and universe work, geographical explorations, archaeological discoveries and scientific breakthroughs.
