Why does Eliezer’s father ask him,”Do you remember Mrs. Schachter in the train?”?

Because his father is having the realization that she was right and that they were all going to die in the fire. (Of course they didn't but...that's what they thought at the time)

Explanation:

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and saw all the stuff he was working on. the lightbulb, film and the transmitter. as he walks in an idea hits him on how the lightbulb would work. he would have to change a few wires around to get it to light up. when he did change the wires around it worked so he decided to write a telegraph to his friend to tell him about his success.   as he was packing up he grabbed the telegraph and walked to his home. he told his wife about the success and the next morning mailed the telegraph.
