There are two major hypotheses: ... natural spillover ... laboratory-associated mechanism. ... Neither hypothesis can be ruled in, nor ruled out. Both are plausible.

Statement relation comments

AI Verified The quote is directly about the exact lab-origin versus natural-spillover question and explicitly says there are two major hypotheses, with neither ruled in or out and both plausible. That gives a determinable abstention/uncertainty signal on the COMPLETE statement rather than support or opposition.

Vote answer comments

AI Verified He is explicitly undecided: the quote says the lab-related and natural-spillover hypotheses are both plausible and that "Neither set of hypotheses can be ruled in, nor ruled out." In the cited testimony, he also says he "will not offer a personal opinion" about which is more likely.
