The difference between "False" and "Cannot Say" decides most verbal reasoning scores. Here is the rule that makes it obvious.
Answer False only when the passage contradicts the statement. Answer Cannot Say when the passage simply does not give enough information to decide - even if you personally know the answer. You judge strictly on the text in front of you.
The trap is using outside knowledge. If the passage does not state or clearly imply it, you cannot call it True or False, however obvious it seems. Practising this rule until it is automatic is the fastest way to lift a verbal score.
