Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair:

Instruction: 
```
The following is an excerpt from an article. Determine the sentiment of the statement made by the person referenced in the quote (Anger, Confusion, Hunger, Fear, Joy, Indecisiveness, Pain or Forgetfulness):

The Candace host also said on the micro-blogging platform: "Conservatives and all people with a moral conscience should never shop at Target again."
```
Response: 
```
The sentiment of the statement made by the person referenced in the quote is anger. The person quoted in this article (Candace Owens) is expressing anger at the store's (Target) unveiling of "tuck-friendly" swimsuits in advertising geared toward LGBTQ+ customers.
```

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Classification. Ensure that the responses are informative and accurate, suitable for an educational context.

Store the generated pairs in JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance:

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]}

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
