Question

what is the indirect object some families prepare their ancestors food

Answer 1

an example is. She gave the beggar a gold coin.
(Step 1. Find the verb = gave)
(Step 2. Ask What? = a gold coin)
(Therefore, the direct object is a gold coin.)
(Step 3. Ask Who (or what) received it? = the beggar)
(Therefore, the indirect object is the beggar.)
Remember, once you have found the direct object, you have to ask who (or what) received it to find the indirect object.
