Complete selected source

Complete original Paper Gate fiction: at the same story morning time, reporter Jun describes no visible water on the surface of the covered indoor sill, and reporter Les describes visible water on the open paving patch from the ordinary indoor viewpoint. They name different surfaces. Neither reports a rain gauge, amount, the cause of the water or what the other surface looked like at another time. The selected question is whether the reports of one same surface at that time agree. No same-surface pair is supplied yet. No actual learner or peer viewing occurs here.

1. What feature did each reporter describe?

2. Do they describe the same surface? Can we compare? Why?

3. What would you like to ask the reporters?

4. What might a same-surface note add? Why?

Use paper or usual communication. No printer or all-four completion needed. A comparison uses the genuine old contribution, never a model.
