This basically says, if you reference an evidence page in a question page, then the evidence informs the question, and the question is informed by the evidence.
Evidence supports claim
This basically says, if you indent an evidence page underneath a block that references the "SupportedBy" page, and indent that under a block that has a claim in it, then the evidence supports the claim, and the claim is supported by the evidence.
Evidence opposes claim
This is very similar to the "Evidence Supports Claim" relation pattern, with the exception that the "linking block" references an "OpposedBy" page instead of a "SupportedBy" page.
