A Paco y Juan *les* falta el trabajo, speaking of other person in plural
Since the underlined word is not appearing, I can infer the word is eat.
For you to understand it better I am going to translate the sentence.
Susana and her family eat tomatoes.
So yes the answer would be eat!
Hope this helps

If you are answering a question you can start with Me gusta or no me gusta if the noun you are talking about is plural then you say gustan
