Choose the best revision of the sentence that contains the error.

The tour guide who has become, a good friend is, great!

The tour guide who has become a good friend, is great!

The tour guide, who has become a good friend is great!

The tour guide, who has become a good friend, is great!

​

Answer 1

The tour guide, who has become a good friend, is great!

Step-by-step explanation:

The commas help separate the two ideas in one sentence correctly. A good way to check that this is correct is to remove the words separated by the commas - "who has become a good friend" - and check if the sentence still makes sense. In this case it would be "The tour guide is great!" which makes sense as a sentence. Thus, this version of the sentence is correct.
