Question

Correct the sentence 1 Arthur has 12 years old 2 This is robert and her sister sue

Answer 1

Arthur is 12 years old
Robert and his sister

Answer 2

1. The correct way to phrase the first sentence is: "Arthur is 12 years old." The verb "is" should be used to indicate age.

2. The second sentence needs some correction. It seems like there might be a gender pronoun error. If Sue is Robert's sister, then the corrected sentence could be: "This is Robert and his sister, Sue." Here, I've changed "her" to "his" to match the gender of Robert. If Sue is a female, then the sentence is correct as it is.
