After her death, Victor seems to feel remorse and guilt because he is aware of what he did, because of the monster he created two family members are dead. Bu, at one point, these feelings turned into anxiety, it might give the reader the idea that he is impossible to figure out. This attitude might foreshadow what happens in Geneva and his decision of keeping the monster alive. It might be interpreted that more obscure things are about to happen.
I believe you are referring to this text:
<span>In the eighteenth century Josiah Wedgwood had made some of the most expensive stoneware ceramics – in jasper and basalt – in Britain, but this tea set shows that by the 1840s, when Wedgwood produced it, the company was aiming at a much wider market. This is quite clearly mid-range pottery, simple earthenware of a sort that many quite modest British households were then able to afford. But the owners of this particular set must have had serious social aspirations, because all three pieces have been decorated with a drape of lacy hallmarked silver.
From the text, the descriptive detail that best aids the reader to visualize the central topic which is a specific early Victorian tea set is "</span><span>some of the most expensive stoneware</span>".
I agree with the sentence because every opportunity you have in life, every moment, you have a chance to pick what is right instead of wrong.
