Answer:
She should consider a different topic to research.
Step-by-step explanation:
Since it's clear that Sarah will not find any educational resources on her topic which she needs for her research, maybe she should start looking into other topics. When writing a report, it's important to have evidence to back up your claims - if you cannot find them for your topic, it would be good to consider broadening the topic or changing it completely to something with more background academic research, like in Sarah's case.
