Final answer:
The term 'corroborates' in sentence 35 means that certain facts or evidence support and add credibility to the speaker's pre-existing suspicion or belief.
Step-by-step explanation:
In sentence 35, the term corroborates is used within a context to mean that certain facts or evidence support and strengthen a suspicion or belief that the speaker already had. The word 'corroborative' suggests that these facts are not only consistent with the speaker's previous conclusions but also reinforce the validity of those conclusions, adding weight and credibility to their suspicions.
To corroborate in this context is to provide additional support or proof that confirms or strengthens an initial idea, argument, or hypothesis.
