A Claim is an argument without a reason.

A Counter Argument (CA) is an Argument that does not support the main conclusion.

Tips

Copy out reasons, arguments etc Word for Word

Try to avoid elipses (...)

As you read the text annotate reason, conclusions, evidence, examples etc.

Underline key points, names etc ... you may be asked to refere to these and it makes it easier to find them.

If you don't know, come back to it later.

If you still don't know, guess.
