Read the following poem and answer the question that follows :

In Those Days

In those days - they were long ago-
The snow was cold, the night was black.
I licked from my cracked lips
A snowflake, as I looked back

Through branches, the last uneasy snow.
Your shadow, there in the light, was still.
In a little the light went out.
I went on, stumbling_till at last the hill

Hid the house. And, yawning,
In bed in my room, alone,
I would look out: over the quilted
Rooftops, the clear stars shone.

How poor and miserable we were,
How seldom together!
And yet after so long one thinks:
In those days everything was better. 

What does the poet mean by the phrase "quilted roof tops"?

Roof top covered with snow

The correct answer is Option (2) - Roof top covered with snow
