2. "rejected" - This is the past tense of the verb "reject," which means to refuse or dismiss something.

3. "the findings" - This refers to information or conclusions that have been discovered or arrived at through investigation or research.

So when we put it all together, "He'd rejected the findings" means that the male subject of the sentence refused or dismissed the information or conclusions that were discovered or presented to him.
