Question

claim
studying poetry helps students to become more effective writers.
evidence
my tutor told me that poetry teaches writers to be aware of all of the different meanings words can have.
strong
weak: doesnt support the claim
weak: not a fact
weak: not from a credible source

Explanation:

The evidence is based on what "my tutor" said. A tutor's opinion alone (without further data, research, or established literary - linguistic principles presented) is not a widely recognized or objective credible source in an academic context when making a claim about the general effect of studying poetry on writing effectiveness.

Answer:

Weak: Not from a Credible Source
