Answer:
Supporting the anecdotal evidence with empirical evidence by examining a range of school handbooks from various public schools.
Step-by-step explanation:
In this excerpt, it is unclear whether the analogy given can really apply to all public schools. The claim that the handbook of the school is like a code of law is too anecdotal. A way to improve this claim would be by supporting it with empirical evidence. In particular, examining a range of school handbooks from various public schools would strengthen the argument significantly.
