Question

complete the sentences with the correct word or phrase.
at the science fair, hwan received recognition for his project because it was excellent. however, sophie helped him with it, so he gave her recognition for her contributions by telling her all about his success making sure to follow her advice adding her name to his poster

Explanation:

The context is about giving recognition for contributions. "Adding her name to his poster" is a direct way to publicly acknowledge her help. "Telling her all about his success" focuses on his own success, not her contribution recognition. "Making sure to follow her advice" is about taking advice, not giving recognition.

Answer:

adding her name to his poster
