What are compared in the following lines? What are the two unlike objects have in common?

1. Eyelids like feather's edge
Tresses long and black as night,
Lips and cheeks like jasmine blossoms...

2. The lovely poems, like dancers in my mind.

3. I sit alone,
Thinking sharp thoughts as warm less as the glacial sun,
I sit alone like a frozen rock
Left and embedded deep in glacial rivers---lovely.

4. Like silent, hungry sharks that swim in the darkness of the sea,
the German submarines arrived in the middle of the night.

5. Silence dropped like a curtain around them.



I think that is no. 1 and 3
2 4 2
Every number, there has to be something that needs comparison.
