My provision of the salt, which had never been renewed since the date of the first experiment, began to run low. I sent out for
a fresh supply and mixed the draught; the ebullition followed, and the first change of colour, not the second; I drank it and it was without efficiency. You will learn from Poole how I have had London ransacked; it was in vain; and I am now persuaded that my first supply was impure, and that it was that unknown impurity which lent efficacy to the draught. What is the complication in this excerpt?
A. Dr. Jekyll’s formula will work only with an impure salt he can no longer find.
B. Dr. Jekyll has forgotten the secret formula needed to make his transformation.
C. Mr. Poole finds Dr. Jekyll’s chemicals and is trying to use them himself.
D. Mr. Poole has discovered and disclosed the true identity of Mr. Hyde.
It's A. He explains in the excerpt how he thinks it was an impurity that made the draught work. Now that he doesn't have the original salt anymore, the draught isn't working.
Answer: A) Dr. Jekyll’s formula will work only with an impure salt he can no longer find.
Explanation: in literature, a complication is a problem or difficulty that makes a situation harder to deal with, it ofted leads to the development of the major conflict of the story. In the given excerpt from "The Strange Case of Dr. Jekyll and Mr. Hyde" by Robert Louis Stevenson, we can see that the complication is that Dr. Jekyll's formula will work only with an impure salt he can no longer find, so the correct answer is option A.
