Why do children … adults' conversations?

1. Analyze the question The sentence is "Why do children _ adults' conversations?" We need a phrasal verb that means to interrupt a conversation someone else is having.

2. Explain the concept Phrasal verbs with "break" change meaning depending on the preposition:

• break up: to end a relationship, or to separate or disperse (a crowd, a fight, a meeting)
• break down: to stop working (a machine or vehicle), to collapse emotionally, or to analyse something into parts
• break into: to enter by force, or to interrupt or join in abruptly (e.g. "He broke into our conversation")
• break off: to stop something suddenly, or to detach a piece (e.g. "She broke off the engagement")

3. Step-by-step solution

• The children are not ending the conversation, so "break up" and "break off" do not fit well. "Break off" would mean the children themselves stop their own talking, or end a conversation on purpose.
• "Break down adults' conversations" makes no sense in this context, because conversations do not "break down" in this way, and children are not analysing them.
• "Break into adults' conversations" means to interrupt or intrude on them, which is exactly what children often do. This fits perfectly.

4. Answer The correct option is C. break into.

5. Exam tip For phrasal verbs, ask yourself what the preposition adds: "into" suggests entering or intruding, which links to the idea of interrupting. Learning each phrasal verb with a short example sentence helps you remember it quickly in the exam hall. For instance: "It is rude to break into other people's conversations."
