Alcohols and PhenolsRead the following lines from Chapter 2 of Oliver Twist by Charles Dickens.
'Please, sir, I want some more.'
The master was a fat, healthy man; but he turned very pale. He gazed in stupefied
astonishment on the small rebel for some seconds, and then clung for support to the
copper. The assistants were paralysed with wonder; the boys with fear.
'What!' said the master at length, in a faint voice.
What do you understand about the situation from the dialogue?
Ecstatic
Shocking and Tense
Calm
