Given the statements about cross-examination ██
An absolute prohibition ██ ███████████ ████████ ██ █████ ██████ ██ ███ ██████████
The referenced claim in passage B says that the adversarial structure of cross-examination is a good way to deal with scientific evidence. Nothing about that contradicts author A’s claim that it’s okay for judges to sometimes do independent research. Author B would say sure, expert witnesses can be cross-examined and then trial judges can do independent research too, if they want.
The adversarial system ██ ████████████ ██████████ ██ ████████ ███████████ ██████████
Author B would take issue with this claim. He has a positive view of the adversarial system’s ability to deal with scientific evidence by subjecting expert witnesses to cross-examination.
Scientific admissibility decisions █████ ████████████ █████████ ████ ██████ ██████
This says that when a judge decides to allow or block certain scientific evidence, it has a downstream effect on what kinds of evidence are allowed in future trials. The referenced claim in passage B says that the adversarial structure of cross-examination is a good way to deal with scientific evidence. There’s nothing contradictory in these two ideas. Author B would say sure, judges can make decisions about what evidence to allow. And then expert witnesses can be cross-examined over the evidence that’s allowed.

This isn’t a claim made by author A.

The referenced claim in passage B says that the adversarial structure of cross-examination is a good way to deal with scientific evidence. Nothing about that contradicts author A’s claim that trials put guardrails on independent research. Author B would say sure, expert witnesses can be cross-examined through the course of a trial, and if trial judges want, they do some independent research within the bounds of the trial structure.
