Using personal knowledge and background information to answer questions in the Listening section can be beneficial in some cases. However, it is important to exercise caution and use this approach strategically. Here's a detailed explanation of how you can utilize your own knowledge while answering Listening section questions:

1. Understanding the Context:
- Your background knowledge can help you understand the context of the listening passage. Familiarity with the topic can provide you with a general understanding of the subject matter.
- For example, if the listening passage is about climate change and you have prior knowledge about this topic, it can assist you in comprehending the content more easily.

2. Predicting Possible Answers:
- By using your own knowledge, you can make informed guesses about potential answers before they are mentioned in the audio.
- For instance, if the question is about a famous historical event, your background knowledge about history can help you anticipate the possible answer options.

3. Inferring Meaning:
- Sometimes, the listening passage may contain unfamiliar vocabulary or complex language. In such cases, your own knowledge can be used to infer the meaning of certain words or phrases.
- By drawing on your background information, you can make educated guesses about the intended meaning of certain terms, aiding your comprehension of the passage.

4. Filling in Gaps:
- Occasionally, the audio may contain missing information or incomplete sentences. Your own knowledge can be employed to fill in these gaps and derive a logical answer.
- If there is missing information in the passage, your background knowledge can help you make logical connections and arrive at a plausible answer.

5. Avoiding Overreliance:
- While personal knowledge can be helpful, it is vital to remember that the Listening section primarily assesses your ability to comprehend spoken English.
- It is important to rely primarily on the information provided in the audio rather than solely depending on your own knowledge. Pay close attention to the details in the passage and use your background information as a supplement.

In conclusion, using personal knowledge and background information can be advantageous in the Listening section of IELTS. It can aid in understanding the context, predicting possible answers, inferring meaning, and filling in gaps. However, it is crucial to strike a balance and not overrely on personal knowledge, as the main focus should be on comprehending the audio material accurately.
