The simple predicate is "did not know that"
Had to look for the options and here is my answer. Based on the given lines from the poem "A Meeting with Despair" written by Thomas Hardy, the line that shows that the poet still finds some hope despite the despair is this: "I glanced aloft and halted, pleasure-caught". Hope this helps.
"Everything that was said to me I seemed to have heard before, and I could no longer listen. I could no longer sit in little bars near Grand Central and listen to someone complaining of his wife’s inability to cope with the help while he missed another train to Connecticut."
