Answer :
To complete the sentence with the best relative pronoun, we need to connect the two clauses effectively. Let's analyze the sentence:
"In 1733, English theologian and chemist Joseph Priestley invented soda water, bubbles and carbonation he mistakenly thought could cure scurvy, a disease caused by a deficiency of vitamin C."
To make the sentence clear and concise, we can use the relative pronoun "which" to refer to the previous noun "carbonation." This creates a smoother transition between the two clauses. Here is the revised sentence:
"In 1733, English theologian and chemist Joseph Priestley invented soda water, bubbles and carbonation, which he mistakenly thought could cure scurvy, a disease caused by a deficiency of vitamin C."
By using "which," we specify that it was the carbonation that Priestley thought could cure scurvy. This helps clarify the relationship between the invention and his mistaken belief, making the sentence more coherent.
