Final answer:
The student's sentences have been rewritten by replacing the underlined nouns with the suitable pronouns. 'Charlotte' becomes 'she', 'a picture' becomes 'it', 'Trudy' becomes 'her', 'Ed and Saira' become 'they', and 'Zac' becomes 'him'.
Step-by-step explanation:
The question is asking about replacing underlined noun phrases (Charlotte and a picture, Trudy, Ed and Saira, Zac) with suitable pronouns within the sentences given. In using pronouns, we replace nouns and noun phrases to avoid repetition and make statements more effective. Here are the revised sentences:
1. She made a picture for her, then gave it to her.
2. They lost him, so they went to look for him.
In the first sentence, 'Charlotte' is replaced with the pronoun 'she', 'a picture' is replaced with 'it', and 'Trudy' is replaced with 'her'. While in the second sentence, 'Ed and Saira' are replaced with 'they', and 'Zac' is replaced with 'him'.
