1. My friend and I are writing a letter - Present Continuous

Answer 3

Sure, I can help you correct the sentence. There are two errors in the sentence you provided:

1. The subject pronoun should be "we" instead of "I" since there are two people involved.
2. The correct verb form is "are writing" instead of "is writing" to match the subject "we."

Corrected sentence: "My friend and I are writing a letter."
