Input: Read this: UN forces retreated to Suwon in the west, Wonju in the center, and the territory north of Samcheok in the east, where the battlefront stabilized and held. The PVA had outrun its logistics capability and thus were unable to press on beyond Seoul as food, ammunition, and materiel were carried nightly, on foot and bicycle, from the border at the Yalu River to the three battle lines. In late January, upon finding that the PVA had abandoned their battle lines, General Ridgway ordered a reconnaissance-in-force, which became Operation Roundup (5 February 1951). A full-scale X Corps advance proceeded, which fully exploited the UN Command's air superiority, concluding with the UN reaching the Han River and recapturing Wonju.
Question: Why was the PVA unable to advance beyond Seoul?

Output: The PVA had outrun its logistics capability

Input: Read this: Jehovah's Witnesses have been accused of having policies and culture that help to conceal cases of sexual abuse within the organization. The religion has been criticized for its "two witness rule" for church discipline, based on its application of scriptures at Deuteronomy 19:15 and Matthew 18:15-17, which requires sexual abuse to be substantiated by secondary evidence if the accused person denies any wrongdoing. In cases where corroboration is lacking, the Watch Tower Society's instruction is that "the elders will leave the matter in Jehovah's hands". A former member of the church's headquarters staff, Barbara Anderson, says the policy effectively requires that there be another witness to an act of molestation, "which is an impossibility". Anderson says the policies "protect pedophiles rather than protect the children." Jehovah's Witnesses maintain that they have a strong policy to protect children, adding that the best way to protect children is by educating parents; they also state that they do not sponsor activities that separate children from parents.
Question: What religion is one of the best at protecting children from molestation?

Output:
unanswerable
