Q. The distant past when there was no paper or language or the written word, and hence no books or written documents, is called 'prehistory'. Our knowledge about art and culture of prehistoric times is deduced from:

1. Pure imagination
2. Materials available from excavation sites
3. Drawings on cave walls.

Which of the above is / are correct?
Answer: Only 2 and 3
Notes: Our knowledge about art and culture of prehistoric times is deduced largely from materials available from excavation sites and drawing on cave walls. Excavation at these places brought to light old tools, pottery, habitats, bones of ancient human beings and animals, and drawings on cave walls. By piecing together the information deduced from these objects and the cave drawings, scholars have constructed fairly accurate knowledge about what happened and how people lived in prehistoric times. Thus, c is the correct answer.
