Final answer:
The best answer to avoid redundancies in the given sentence is to use the phrase 'in which' instead of 'being the place in which'.
Step-by-step explanation:
The best answer to avoid redundancies in the given sentence is to use the phrase 'in which' instead of 'being the place in which'.
Using 'in which' eliminates the redundancy because it combines the ideas of location and appearance into one concise phrase. This makes the sentence more clear and concise.
With this change, the sentence would read: 'He then wrote an enthusiastic article for Strand Magazine, in which most of his Sherlock Holmes stories had first appeared, and later wrote a book on the subject titled The Book of the Fairies.'
To avoid redundancies in the given sentence, the best option is in which. This option eliminates the unnecessary repetition of the concept of place, thus streamlining the sentence. Therefore, the revised sentence should read: "He then wrote an enthusiastic article for Strand Magazine, in which most of his Sherlock Holmes stories had first appeared, and later wrote a book on the subject titled The Book of the Fairies." This eliminates the redundancy, providing a concise and clear statement.
