Question

1. you are looking up at the chimney from the fireplace. what do you say?

there is a heavy creosote deposit
the chimney walls are rough
we should be able to see daylight at the top
the damper has been left in the open position
the damper is missing

Explanation:

When looking up a chimney from the fireplace, a key check is if daylight is visible at the top (indicating the chimney is open/clear for ventilation). Creosote deposit is about buildup (not directly seen by just looking up), rough walls are a structural detail not the main check, and damper status (open/missing) is about the damper (a different component, not the main visual when looking up the chimney shaft). So the most relevant observation when looking up is checking for daylight at the top.

Answer:

C. We should be able to see daylight at the top
