Identify the three mistakes and type the correct answers.
The producer director and film editor has all went to the Cannes Film Festival
1. The verb "has" should be changed to "have" to agree with the plural subject "producer, director, and film editor."
2. "Went" should be changed to "gone" for proper tense agreement.
3. "Cannes Film Festival" should be capitalized as it is a proper noun.
Corrected sentence: The producer, director, and film editor have all gone to the Cannes Film Festival.
