This exercise focuses on different types of evidence. Remember, not all types of evidence are strong enough to help you prove something.

When you read an academic text, you are expected to ask yourself questions such as:

On what evidence has the writer based his claims?
Is this evidence strong enough to support the writer's claims?

The following types of evidence often appear in academic texts:

ambiguous evidence – can lead to more than one conclusion.
conclusive evidence – leads to only one possible conclusion.
insufficient evidence – not enough evidence to prove something.
consistent evidence – studies by different researchers reach similar conclusions.
