A coat hanger swings from the reading lamp above the Signal Desk, a paper cup tied to each end.
"A balance," Rocket says. "For weighing evidence. Letters go in the Signal this week, and some are heavier than others."
Raven unfolds a letter about a bench by the skate ramp and reads the first line. "What do you notice about it?"
"It tells us what the writer wants. A bench."
"That is the claim," Raven says. "Now find the reasons, and then find what holds each reason up."
Nova hovers beside the hanger, her light making it sway. "A claim with nothing under it floats away," she says. "Evidence is what gives it weight."
Rocket writes CLAIM on a card and drops it in the cup. The hanger barely moves.
A claim is what the writer wants you to believe or do. A reason is why the claim is true. Evidence is a fact, example, count or quotation that backs up a reason.
To trace an argument, find the claim first. Then list each reason. Then, under each reason, find its evidence.
Raven thinks aloud: "The text says skaters have nowhere to wait. That is a reason. Then it says the writer counted twelve people standing. That count is the evidence for the reason."
A claim can be supported or unsupported. A supported claim has reasons and evidence behind it. An unsupported claim stands alone.
This letter ran in this week's Signal. Letters to The Signal are written by neighbors, and the crew prints them as they come.

Claim found, reasons listed, evidence weighed. Tomorrow some claims turn out to have nothing under them.
