Answer:
The witches gather on the moor and cast a spell as Macbeth and Banquo arrive. The witches hail Macbeth first by his title Thane of Glamis, then as Thane of Cawdor and finally as king. They then prophesy that Banquo's children will become kings. Macbeth demands to know more but the witches vanish.
indirect object
An indirect object is the receiver of the direct object. The assembled children are the ones who are receiving the information the meteorologist is telling. The subject of the sentence is who or what the sentence is about. The meteorologist is the subject of this sentence. He is doing the action. A predicate nominative renames the subject. It follows a linking verb. There is no linking verb in the sentence so predicate nominative is not an option. An appositive is a noun phrase that renames or describes the noun next to it. For example Sarah, my sister, is late. My sister is an appositive; it renames Sarah as my sister.
