Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
It is only possible to identify the quote you need, reading each quote, however, as you want a quote where Lena convinces Sammy that he is contributing to the family, we must consider that the correct answer is the quote where Lenna presents the good things that Sammy did for the family and how it has helped the family in different situations. You should look for the quote that looks something like this, to answer that question.
