Answer:
The indirect object in the sentence above is "Philip".
Step-by-step explanation:
The indirect object of a sentence is the recipient of the direct object. In this case, that recipient is "Philip" as he is the one to whom Cassandra told the time of the match.
Before you find the indirect object, you should identify the direct object. You can find the D.O by finding the verb and asking what? Once you have found the direct object, ask who or what received it? For instance, what did Cassandra tell Philip? The time of the match (D.O) and who did she tell it? Philip (I.O).
