Simple question ~ simple answer....?

It means 'Henry's one wall'. This rhetorical technique, where a word is not repeated, is called 'zeugma'. E.g.

"Mary ate an apple, John a banana and Susan an orange." The word 'ate' is not repeated but is implied. It's much quicker than saying, "Mary ate an apple, John *ate* a banana and Susan *ate* an orange."

We don't necessarily have to repeat the word 'ate' because we already know what's happening.

Yes, one wall. The implication is that Henry's father did a LOT more work than Henry did.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
