Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde.

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.

Respuesta :

The answer is A. Dr. Jekyll's formula will only work with an impure salt, which he can no longer find.

It is the impurity of the salt which Jekyll believes lent efficiency to the draught.

Answer: a. Dr. Jekyll’s formula will work only with an impure salt he can no longer find.

In this excerpt, Dr. Jekyll discovers that he has very little salt left, and sends someone to get him some more. However, when he uses the new salt in his potion, it does not have the desired effect. The only logical conclusion is that the salt he had previously bought had some type of impurity that made it effective. However, he does not know what this element was or how he can find it again.
